Re: [PHP] validating mysql bound date

[Larry Brown]

Thanks,

I ended up doing:

$incomingQuestDatePieces = explode("-", $incomingQuestDate );

if(checkdate($incomingQuestDatePieces[1],$incomingQuestDatePieces[2],
$incomingQuestDatePieces[0]))
{
return true;
}
else
{
return false;
}


I was just wondering since a lot of people have to verify correct format
of the date when working with mysql that there might be some built in
that is faster etc.  

Thanks though...

I normally provide dropdown fields for each (except the year which is a 
text-field) and put it together how I need it. Validate each part 
separately and you're off and racing.


If you accept any date you'll probably have to split it up first but the 
principles will be the same.



$date = '-00-00';
// if they didn't use exactly two dashes? invalid
if (substr_count($date, '-') !== 2) {
  die("Invalid date");
}

list($year, $month, $day) = explode('-', $date);
if (strlen($year) != 4) {
  die("Invalid year");
}


and so on.

PHP color.php
list($coords) = array_keys($_GET);
$coords = explode(',', $coords); // Easier way...?
$im = imagecreatefrompng('colormap.png');
$color = imagepixelat($im, $coords[0], $coords[1]);
I wouldn't do it like this, though. I'd use Javascript.

[PHP] validating mysql bound date

[Larry Brown]

Does anyone know if there is a builtin function for checking the
formatting of an incoming date to verify it is /MM/DD.  I know how
to convert between formats but want a quick way to check an incoming
variable to ensure it will be handled properly by mysqld.

Richard, Jed,

Thank you for replying.

The .htaccess file for phpMyAdmin says "php_flag magic_quotes_gpc Off", 
so I guess that means I'm okay there.



Other than that, it's specific to phpMyAdmin, so maybe ask those guys
what they did...


I joined their list through Sourceforge, but I haven't seen any mail

the issue is.

If you're having trouble importing a mysql dump using phpMyAdmin, it might be simpler not to use it, and use mysqldump instead. 


I suppose I'll have to if I can't get phpMyAdmin to behave. It's too

Re: [PHP] 2 Questions: Static variables and the nature of the online manual

[Svevo Romano]

Yes Richard,

In fact I know ActionScript and JavaScript and I'm trying to nail the
peculiarities of php. I totally agree. I am not used to use ' -> ' to call a
method if you know what I mean, but the rest is quite familiar, phew! :)
Aside from that, this was just one of the things I could not really
understand properly: I could understand the effects, not the reasons behind
the effects, if it makes any sense. I think the manula is lacking a couple
of lines.

One funny thing: in the Welling Thomson - PHP and MySQL Web Development
book, at some point this thing is mentioned. They promised they would
explain the concept in full detail in chapter 5 and, in chap 5, they kinda
forgot to do it.. hehe

All the best.

Re: RES: [PHP] 2 Questions: Static variables and the nature of the online manual

[Svevo Romano]

Cheers Thiago,

In fact this was going to be my next question. I think I will report a
documentation bug, just because, after all the discussion we had today, I
realize that this is quite a common behaviour in other languages, but for
somebody new to languages, being them programming or scripting ones, the
fact that the $a=0 line doesn't get executed on subsequent calls isn't so
obvious.

In other words, from the standpoint of someone that is relatively new to the
details (at least), the flow is: 'ok, I do appreciate that the engine keeps
memory of the value of that variable declared as static after the function
ends, but assigning a value to it at the very beginning of the function
seems like the next time the function is going to be called, it will assaign
that value again and again...and again'.

And I guess the manual wants to be as clear as possible, considering that
the examples are often 'foo 'and '$a' related :P In other words I think that
it is indeed targeted to beginners as wel, isn't it?

Thanks for all the valuable info btw. :)

No.

For starters, all the core developers are very committed to PHP being
Open Source.

Secondly, Zend has gone "on record" saying that the Zend Engine will
always be Open Source.  I know, cuz I said so when I worked there. :-)

Who owns any GPL for FOSS-licensed software?

The community.

The community.

There are MORE than enough users who would fork it in an instant if

I dunno about iMac or MacBook, but I saw a TON of Macs with dodgy
monitor settings all the time back in the day!

Sometimes on the desk of Graphic Artist who then got cranky when their
images were messed up on a well-tuned monitor...

So unless Apple has perfected the auto-tuning of a monitor or
something, I'd be surprised if it *was* correctly-tuned.

Re: [PHP] PHP performance

[Richard Lynch]

#1
Get the code, install it on a box in the closet, run valgrind --callgrind

This will give you a stack trace of what gets called the MOST in your
application.

Look for "tall" trees in the call graph, and fix those first.

#2
You can use 'ab' (apache benchmark) or similar to test it externally.

#3
You can also script things with Selenium IDE and then use Selenium
remote control to run them repeatedly, for the end-user experience.

Don't let server non-access stop you from doing #1 though...

RE: [PHP] GPS Locator

[Daevid Vincent]

While this has deteriorated way off topic from PHP, I will just mention that
I've purchased several GPS from these cats and had great luck:
http://www.buygpsnow.com

You *might* be able to write a custom PHP extension that you compile into
PHP that can access the USB/Serial port as well. (and if you did got this
route, which would be the most beneficial to the PHP community, I hope you
would FOSS the extension so other's could use it perhaps)
http://devzone.zend.com/node/view/id/1021

Secondly, maybe you could have a little daemon written that simply spits out
the coordinates (lat/long/altitude/etc.) to a socket or something, and then
via PHP's socket functions you could continually read that in.

Alternatively, perhaps JAVA will also let you access hardware layers if
you're on a non Microsoft platform (which is generally the case for PHP
users).
 
Lastly, you could certainly do some low level hardware I/O with Ruby and
then perhaps use Rails for the web portion.

Chalk this all under the "best tool for the job" category, in this case I
doubt PHP is.


Daevid.

Remember, when coding, php.net and google are friends.  
Everyone else hates you.  
It is not personal, it's just a fact.

Please include the list when replying. And please don't top-post, it

(I should told you that before, sorry!!) and then I started to look  
at php web site and I found:


sendmail_path string
Where the sendmail program can be found, usually /usr/sbin/sendmail  
or /usr/lib/sendmail. configure does an honest attempt of locating  
this one for you and set a default, but if it fails, you can set it  
here.


Systems not using sendmail should set this directive to the sendmail  
wrapper/replacement their mail system offers, if any. For example, »  
Qmail users can normally set it to /var/qmail/bin/sendmail or/var/ 
qmail/bin/qmail-inject.


qmail-inject does not require any option to process mail correctly.

This directive works also under Windows. If set, smtp, smtp_port and  
sendmail_from are ignored and the specified command is executed.


My mistake, the comments in the INI file really should be changed to  
reflect that.


Given that your problem is that you haven't uncommented that line as  
Shawn said. Remove the ; from the start of that line, restart your we  
server and if the manual isn't lying it should work.


Incidentally, it probably didn't like the Yahoo settings you used  
because that port is for SMTP over SSL which PHP doesn't support.

Re: [PHP] Fatal error: Call to a member function web_order_change() on a non-object

[Richard Lynch]

register_globals got turned off.

All your $_SESSION variables (in your case, $_SESSION['SESSION']) need
to be reference explicitly now.

Add this at the top:

$SESSION = $_SESSION['SESSION'];
right after session_start();

That's how it works in C.

And Ada.
And Pascal.
And even Lisp.

After you've learned a couple computer languages, the rest are mostly

Ok, except the Lisp/Scheme/Prolog stuff, where you have to think

Number 1, in php.ini you left this uncommented so it's using this:
SMTP =
smtp_port =

Number 2, here you didn't uncomment the ;sendmail_path:
; For Unix only.  You may supply arguments as well (default: "sendmail
-t -i").
;sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"

Also, notice the *For Unix only.* comment.  Dunno if it will work anyway
if you have sendmail.

You need to point the "For Win32 only" settings at a mail server on  
Windows. The error message pretty clearly states that it's trying to  
connect to the server specified in those settings.

It's not an assignment, it's an initialization, and, yes, the compiler
does "keep track" and doesn't do that after the first time.

*THIS* would be what you describe:
function Test(){
  static $a;
  $a = 0;
  echo $a;
  $a++;

The manual is contributions from volunteers who have been "blessed" by
the other volunteers (viz) to edit the manual.

The "Notes" is from anybody on the planet with a web browser that can
beat the CAPTCHA.

There is nothing you can buy that's more official (nor more complete)
than the on-line manual.

You can buy support from Zend, which is a separate company run by two
guys who happen to be core developers;  You can probably buy support
elsewhere as well.

PS
If you can find a language with a better manual, I'd like to see it...

figure out what's going on with the system for his boss, but that
script has cause php to segfault once already, and he is also trying

an ancient Compaq Proliant, so pretty much posts while waiting for the

Woof.

So anybody with half a clue could look in their cookies and change,
say, 'id' to '1' and masquerade as anybody they want in your system.

And with an 'id' of '1', they might even getting CMS 'admin' access or
something.

Probably not a Good Idea...

You could, perhaps, use a 2-way encryption algorithm and try to keep
your key as securely as possible, and do this much more safely.

Use robots.txt to keep out "real" search engines.

Anybody who REALLY wants to can run your JS with Webmonkey, the JS
engine of Firefox, released as a stand-alone command line tool.
(E.g., JS email obfuscation is useless against somebody with
webmonkey.  Try it and see!)

What you tried only requires ONE a-z character somewhere in the input.

Try this:

preg_match('^[a-z]+$', $fname);

This will:
^ "anchor" the string at the beginning
[a-z]+ a to z, with at least one letter
$ "anchor" the string at the end

Note, however, that some people have other characters in their first
name, such as apostrophe, space, and dash.

Oh, and the digit 3, for "bo3b" who was a programmer on the first
Apple Macintosh.  His parents were hippies, and that really is his
name...

You may want to obtain a LARGE list of "first names" and run them
through your validator as a test.

Keeping with your example, this works and doesn't allow an empty string
(to allow empty, replace the + with *):

eregi('^[a-z]+$', $fname)
-or-
ereg('^[A-Za-z]+$', $fname)

But ctype_alpha() is a better multi-locale solution.

[PHP] regular expressions question

[Adil Drissi]

Hi,

Is there any way to limit the user to a set of characters for example say i 
want my user to enter any character between a and z (case insensitive). And if 
the user enters just one letter not belonging to [a-z], this will not be 
accepted.

I tried  eregi('[a-z]', $fname) but this allows the user to enter abdg4512kdkdk 
for example.

Thank you

  Let's just get all purist and go back to the class="highlight" so we
  don't find ourselves a year later with a stylesheet that includes

  .red {
 color: green;
  }


Andrew makes a good point, Jason.  Despite the fact that it's just
a reference, it's easier to make a general reference to "highlight"
that can later be changed to weird colors like shale, aquamarine,
coffee, and taupe, than to have a style called "red" and have a future
designer look at the source and say, "damn, that Jason Pruim guy
doesn't know his .red from a #804000 in the ground.


Yes, but there are two points here.

One is if you want to be specific about a design element, then call 
it whatever you please. But, if on the other hand, you want a general 
old-world font-color, or font-bold, or font-whatever, then you can 
use css to do that for you very easily.


I am not saying use class="red" that might later be changed to green 
-- that would be very short sighted. But let's say you have a client 
that wants "BUY" to be red, I don't see any problems with using 
class="red" in your html tag.


Also, later if the client says "That red is bright enough" you can 
always change it to another shade without violating the "red" thing..


If the client say "I want that to be green", you can always refer to 
the design specs that said otherwise; do a global search and replace; 
and bill for your time.


All I'm saying here is to consider easy-to-under semantics in writing 
css rules.

That's much less likely than:

   {

   }

The point is to use css classes and ids to be semantic.

But you should use CSS:

echo '' ...


But if you're going to use CSS.. it would be better for managing it 
to do it as a style sheet:



.red {
color: red;
}


echo '';

Just my opinion :)



And a good one -- other than not putting them in the html, but rather 
in a style sheet.


I see no problem whatsoever in using css to do that and --

.bold
   {
   font-weight: bold;
   }

.floatRight
   {
   float: right;
   }

-- other such obvious style elements. At least those are pretty self 
explanatory.


If you want to get specific, then start naming your classes and id's 
to specific things, like:


#mainTitle
   {
   color: red;
   font-weight: bold;
   float: right;
   }

Do your best to keep all languages separate.

Hi Jochem,

This is probably true.  I was just referring to an old benchmark [1] I
had seen a few years ago.

Of course the biggest win will come from an opcode cache if that is a
possibility.

Just for the record I do use a db wrapper myself but I have weighed
the pros and cons of the situation and determined that it works for
me.  I have many low traffic sites so it makes sense to have a wrapper
that delays connections until they're used and such other little
tweaks.

I listen to peoples recoded talks from conferences and I've heard on
many occasions that on single apps they take out the db abstraction.
I wish I could cite references but it is out there if you want to dig
enough.


duh. ofcourse they do that. remove a layer of abstraction and win some speed.
it a game of dimishing returns, take the big target first - that's usually the
SQL queries, DB tuning. next step might be op-code caching, then data/output 
caching,
and if that's not enough (or you have enough iron in play to make the numbers 
add up)
you start to remove maintainability and/or abstraction from your code to win a 
few
cpu cycles.

php is web-glue, or for the purposes of my metaphor web-butter ... generally the
sandwich is mostly filled with something other than butter.

echo("$char_name

also is it just the 'Seen' flag you can't set or can you not set any
kind of
flag? (from my reading I gather there are a few others e.g.
'Flagged'

I'm not even sure what the 'Flagged' flag does...


I believe it will literally show a little red flag next to a mail in 
Thunderbird,
at least I have a 'flag this' button and it puts a red flag next to the item 
... I never
use it :-)



So I could set it, and then wouldn't know for sure how to check it in
another app.


Well, the "Answered" flag also does not appear to "work", at least as
far as I can see.

PHP IMAP still has 0 for 'answered' and so my webmail client doens't
show a pretty little "A" like it does when I answer email...


so it seems you can't do any kind of 'flagging' with the code you have.

question: what webmail app are you using? written in php by any chance?
worth checking how it sets the flags? maybe break open a copy of roundcube or
something like that and check their code for the tiny little detail you seem
to be missing?

DIO should let you do it, but that extension is pretty buggy last I used
it (OK like 5 years back with PHP4).

What I did was got high end barcode scanners to scan directly into a db
through a long running PHP script with it, so that should work just
fine.

That being said, though, something like a Winders COM object will
probably be a better bet (I have never used COM objects before as I
don't use Windows at all, ever) so correct me if I am wrong please!

Yes.

Use whatever you want. You can use the number characters or find the 
last *space* in a string that's just long enough to fit your limit.


Let's say your limit is 100 characters.

1. First truncate the string to 100 characters.

2. Then search the string for the last space.

3. Then truncate the string at that point and add "...".

It will be a good exercise for you.

Amazingly, I do get all of my stuff done.  Granted, I'm in front
of a computer seven days per week, and usually a minimum of 10-12
hours per day, but what else would I do?  Spend time with the
pre-wife?

Shyeah, right.

No, that would work fine in any case.  In fact, code should always
be thoroughly tested before going into production.

RES: [PHP] 2 Questions: Static variables and the nature of the online manual

[Thiago Pojda]

 

-Mensagem original-
De: Svevo Romano [mailto:[EMAIL PROTECTED] 

Hi there,

Many thanks for your answer. I've also gone through your 
example and it took me 10 minutes to understand how the 
operator precedence was working there.
Was expecting 1 on the first call :)

But this is not the point. You've nailed my question very 
preciseley in your first answer: 'the preceding line is only 
run on the first call to the function'.

My only question is (at it is related to the nature of the 
online manual):
how do you know it and I don't? This thing is the only logical 
explanation to the fact the $a doesn't get initialized again to 
0 in any subsequent call to the function, but it's not written 
anywhere in the manual page. And it seems the most important 
statement in my opinion, that justifies what I see as an 
exception to a normal flow.

Hope all this makes sense.
Thanks,
S

Yes, it should...

Fixed that, but no better.

Since FT_UID === ST_UID === 1, that's to be expected, however. :-(

I would hazard a guess that the 'static' keyword and functionality
comes from ANSI C. I just pulled "The C Programming Language" by
Kernighan and Ritchie from the book case and it is described there in
it.

Essential book, by the way, IMHO.

Yeah people are going to start thinking Richard Lynch and I

he goes under the radar, I hit 123 posts.

I know that this is not a PHP question (but it will work with a PHP app)
but I thought I would ask the smartest group of people I know if they
have any clue or would be familiar with a device I can use. I need to
purchase a small GPS receiver/antenna that will plug into a USB port.
Then I need to access the port (Ajax? Java?) while in my web application

Check the section "Using static variables" in the Variable Scope entry here:
http://us.php.net/manual/en/language.variables.scope.php

Actually, a good portion of us who maintain the manual maintain
the code, as well.  Everything about the language, from the core
engine to web scripting support, is handled entirely by the community.
 That's the beauty of open source.

Ok Jochem,

It makes a lot of sense. Now I know what I can expect from the manual and

We (the PHP community) maintain the manual through registered CVS
accounts.  As Jochem said, php.net is the official manual - there is
no official manual to buy, and no way for a company to document
everything about the language.  This is because, believe it or not,
the language changes multiple times per day, with added functionality
all the time.  The best a company could do is document everything on a
specific version but by the time that task is complete, the
version documented would be obsolete.

The comments are just posts by whomever feels like typing and
submitting.  It's generally a "tips and tricks" sort of thing, and is
an excellent source, but an unofficial source.

Re: [PHP] 2 Questions: Static variables and the nature of the online manual

[Svevo Romano]

Hi there,

Many thanks for your answer. I've also gone through your example and it took
me 10 minutes to understand how the operator precedence was working there.
Was expecting 1 on the first call :)

But this is not the point. You've nailed my question very preciseley in your
first answer: 'the preceding line is only run on the first call to the
function'.

My only question is (at it is related to the nature of the online manual):
how do you know it and I don't? This thing is the only logical explanation
to the fact the $a doesn't get initialized again to 0 in any subsequent call
to the function, but it's not written anywhere in the manual page. And it
seems the most important statement in my opinion, that justifies what I see
as an exception to a normal flow.

Hope all this makes sense.
Thanks,
S

I'm not sure if this is what you are asking for, but occasionally I 
have an include file that just brings functions and sometimes I want 
to know if that file has any errors in it.


As such, I simply add echo('a'); at the beginning of the file. If I 
run the script that includes that include and see an 'a' printed at 
the top of the page, then I know that the include has no syntax 
errors. Then it's simple to comment out that line.

Re: [PHP] maintaining [user] state without a session ...

[Bojan Tesanovic]

Hi,
It depends what do you need to track,
if you need to track small amount of variables you can do it by cookie
I often use it eg here is the state for one user
$state = array{
'logedin'=>true,
'n'=>'Peter',
'id'=>'5',
//anything else you need
}

//at end of you script before outputing any content
//set cookie only for browser session and set path to '/'  so it is  
available through whole site

setcookie('user_data',serialize($state),null,'/');


At the begining of a script

$state = isset($_GET['user_data']) ? $_GET['user_data'] : null;

if( ! $state ) {
 //user doesnt support cookies or this is a search engine set  
default $params

$state = array{
'logedin'=>false,
'n'=>null,
'id'=>null,
//anything else you need
}
}



Also you can use some way to detect if the user is not Search engine  
to display message like
"To properly use this site you need to enable cookies in your browser  
bla bla "


This can be done via JS alert message which will not be triggered by  
SE but only by real user

He might not have loaded the class definition also.  That'd lead to
the nasty __PHP_Incomplete_Class.  Or maybe it is something to do with
class names in php4 weren't case sensitive whereas in php5 they are.
I've used the unserialize_callback_func feature before to auto load
classes.

Oh I just read that Jim said this earlier, but I'm going to post it
anyways after typing it up. ;)

Hi Jochem,

This is probably true.  I was just referring to an old benchmark [1] I
had seen a few years ago.

Of course the biggest win will come from an opcode cache if that is a
possibility.

Just for the record I do use a db wrapper myself but I have weighed
the pros and cons of the situation and determined that it works for
me.  I have many low traffic sites so it makes sense to have a wrapper
that delays connections until they're used and such other little
tweaks.

I listen to peoples recoded talks from conferences and I've heard on
many occasions that on single apps they take out the db abstraction.
I wish I could cite references but it is out there if you want to dig
enough.

The first question has to do with the static variables. I understand how

The example:



the preceding line is only run on the first call to the function.

Of course works (I¹ve tested it on my server), but it is still obscure to
me, according to general programming principles, since I¹m still assigning
zero (0) to $a on each call to the Test function. How does this exactly work
when the static word is found? Is there and index that keeps track of each
call to the function ignoring any assignment in subsequent calls to the
function? Why doens¹t this work when you assign an expression result to the
variable?


do something like

function Test()
{
static $a;

if (!isset($a))
$a = 0;
if ($a % 2)
$a = $a * 2;

echo $a++;
}



The second question has to do with the online manual. I¹ve found several
things on that manual specified in comments and not in the actual manual
part of it. What is the nature of the manual? Contributions from voluteers?
Is there any official manual I can buy that documents everything about the

$static $a = 0;
Here you're essentially saying "new static variable $a with a default 
value of 0" - the fact defined staticly means that next time you call 
the funtion, $a has a value so therefore doesn't need the default.

 If you remove it, then you remove functionality - so before you go

Hi Chris,

These 'benefits' you talk about really only matter if you switch your 
databases.  If this app is written against Oracle and they never plan 
to change it, then it isn't a bad idea to cut out that fat and just 
deal with the native interface.  Even writing wrapper functions that 
are very basic that abstract mysql_query or mssql_query end up adding 
a lot of overhead over lots of requests.  Look at some of the PDO 
benchmarks.  It is slower than the native functions too because it is 
just a wrapper.


Even further if you are writing an app where you care about 
performance you should be writing your SQL to the point where it 
really isn't portable using all the little vendor specific 
features so 

that you get the most out of it.

From my personal profiling most of my application time is spent in 
data access.  So the less layers you have there the faster it runs.


the adodb php layers are insignificant compared to the cost of 
the db connection and the round trip to retrieve data from the 
db. the significant application time you speak of is undoubtly 
spent at the database performing and retrieving the data as 
opposed to measurable overhead caused by a [number of] wrapper 
function[s].


high probability that SQL related tweaks (indexing, query 
restructuring, db tuning) will win you much, much more than 
removing any db abstraction layer



But that is just my 2cents on it.  :)




First of all, thanks for helping me out :)

The vb.net stuff does a lot of business and database stuff, it's
really tied up with the app. Actually I've no idea how it works internally,
all I know is that we send data strings via socket and it returns the
results the same way. It's kind of a black box. :/

I'm going for:
Tune SQL and move a lot of heavy queries directly to
procedures/functions in BD
Tune apache

We had a talk with a sysadmin and tried installing xdebug in the
server, but it's a RHEL4AS w/o php-devel packages (phpize) and we can't find
a RPM for that anyone? :)

[PHP] 2 Questions: Static variables and the nature of the online manual

[Svevo Romano]

Hello,

I got this e-mail address from the ŒAdd note¹ page within the php.net
website. I was going to post something that was a question and I realised I
was in the wrong place :)

I have 2 basic questions and I¹m sorry if they may seem too basic. I¹m a bit
new to php.

The first question has to do with the static variables. I understand how
this works from the examples, but there is something that I cannot seem to
find clearly stated anywhere on that page.

The example:



Of course works (I¹ve tested it on my server), but it is still obscure to
me, according to general programming principles, since I¹m still assigning
zero (0) to $a on each call to the Test function. How does this exactly work
when the static word is found? Is there and index that keeps track of each
call to the function ignoring any assignment in subsequent calls to the
function? Why doens¹t this work when you assign an expression result to the
variable?

The second question has to do with the online manual. I¹ve found several
things on that manual specified in comments and not in the actual manual
part of it. What is the nature of the manual? Contributions from voluteers?
Is there any official manual I can buy that documents everything about the
language from the source? Or any official company that maintains the
language and that possibly offers support as well?

Many thanks in advance for your time.

the adodb php layers are insignificant compared to the cost of 
the db connection and the round trip to retrieve data from the 
db. the significant application time you speak of is undoubtly 
spent at the database performing and retrieving the data as 
opposed to measurable overhead caused by a [number of] wrapper 
function[s].

high probability that SQL related tweaks (indexing, query 
restructuring, db tuning) will win you much, much more than 
removing any db abstraction layer

First of all, thanks for helping me out :)

The vb.net stuff does a lot of business and database stuff, it's
really tied up with the app. Actually I've no idea how it works internally,
all I know is that we send data strings via socket and it returns the
results the same way. It's kind of a black box. :/

I'm going for:
Tune SQL and move a lot of heavy queries directly to
procedures/functions in BD
Tune apache

 If you remove it, then you remove functionality - so before you go and
 rip it out, check whether it's the bottleneck using xdebug.

 I use an abstraction layer all the time and the benefits far outweigh
 the 'costs'.

Hi Chris,

These 'benefits' you talk about really only matter if you switch your
databases.  If this app is written against Oracle and they never plan
to change it, then it isn't a bad idea to cut out that fat and just
deal with the native interface.  Even writing wrapper functions that
are very basic that abstract mysql_query or mssql_query end up adding
a lot of overhead over lots of requests.  Look at some of the PDO
benchmarks.  It is slower than the native functions too because it is
just a wrapper.

Even further if you are writing an app where you care about
performance you should be writing your SQL to the point where it
really isn't portable using all the little vendor specific features so
that you get the most out of it.

From my personal profiling most of my application time is spent in
data access.  So the less layers you have there the faster it runs.

Re: [PHP] imap_setflags_full Seen

[Jochem Maas]

Richard Lynch schreef:

I am trying to use this:

imap_setflag_full($imap, $uid, "Seen", FT_UID) or die("Unable to
mark message as \\Seen");


3 things:

1. shouldn't it be ST_UID iso FT_UID?
2. the imap bos is opened readonly?
3. er ... I l-i-e-d :-)



to mark a message as "read"

It does not seem to have any effect on the return values in
imap_fetch_overview.

Nor does it appear as "read" when I view it with my email client.

The "unseen" count on the mailbox also does not decrease, which I
would expect if it was "working"

Is there some kind of trick I'm missing?

Is there some OTHER flag/function I'm supposed to be using to mark a
message as "Read"?  I sure can't find it in tfm so far...

The $imap stream is valid, and I can fetch the headers and body just
fine.

The $uid is from imap_uid and, again, is used to fetch the header and
body just fine.

I've tried imap_close($imap, CL_EXPUNGE) in the hopes that it would
"write" the changes, but no such luck.

PHP 4.4.7 Hardened
Gentoo 2.6.18 hardened R6 SMP
phpinfo says IMAP c-client Version 2004 w/ SSL support enabled
Gentoo says courier-imap 4.0.6-r2 is installed, so probably using that.

The versions are out of my control, due to a security and stability
focus of this install.

Re: [PHP] Fatal error: Call to a member function web_order_change() on a non-object

[Jochem Maas]

Ben Edwards schreef:

Our server has just been upgraded to PHP 5.2.5 and suddenly I am
getting the following error:

Fatal error:  Call to a member function web_order_change() on a
non-object in /var/www/vhosts/cultureshop.org/httpdocs/cart.php on
line 32

The code is:

$SESSION["cart"]->web_order_change( true );

The command 'global $SESSION;' is the first line of the script.




$SESSION is the session variable created with

session_start();
session_register("SESSION");


don't use session_register(), use the $_SESSION superglobal instead
(notice the underscore) ... you can read in the manual about this.

additionally you need to load in the class before you start the
session.

so the code would look something like:

require 'Cart.class.php';
session_start();

if (!isset($_SESSION['cart']))
$_SESSION['cart'] = new Cart;

function foo()
{
// no need to use global on $_SESSION
$_SESSION["cart"]->web_order_change( true );
}



if ( !isset($SESSION["cart"]) ) {
  $SESSION["cart"] = new Cart;
}

I am guessing this is a change in OO handling, any idea what is going
on and how to fix it?


the crux of the problem lies in the use of outdated session semantics, I'm
guess you've just been upgrade from 4.x, is that correct?

Ben
