... then I'm pretty sure that is generated by your browser and not by the 
server.

When using the image functions I always have them save to file initially, then 
when I know that my code is 100% correct and the saved images are viewable 
*then* I output them directly.

In that case you're doing something different to everyone else, find out what 
that difference is.

Are there any places that might have instructions on compiling PECL

My php is configured to write error messages to the http error_log and

In this case the error is displayed and not logged.

[PHP] Problems displaying images with PHP-GD

[Ian Johnson]

Hello 

I am trying to use GD to create and manipulate images but the
statement: 

header ("Content-type: image/jpg"); 

generates the error message: 

The image "http://localhost/gdtst2.php"; cannot be displayed, because
it contains errors. 

There is no error message in the ../httpd/error_log file. 
I am using PHP 5.0.3 with GD 2.0.28.  The report from phpinfo()
indicates gd present and enabled. Other nongraphics content-types do not
gererate errors. 

Code used was "First Program" from tutorial at
http://www.phpfreaks.com/tutorials/105/1.php.  Similar code from php
manual generates the same error. 

I suspect the solution is simple but I'm just not seeing it! 

Help

"contains errors" here means "It's not a valid JPEG"

So comment out the header() and see if you see any error messages then.

After it looks like it's a JPEG (starts with yoya) put the header() line
back in.

This script only outputs the top level. i.e.

- folder1

|
- folder3

it should be

- /
|
- folder1
|   |
|   - subdir1

- folder2
|   |
|   - subdir2

- file3.ext


I really don't know what I am doing here ;)
It looks like something is creating a new class instead of working with
$tree, after the foreach loop $branch has the intended value.  After
$branch =& tree; the added subdirs exist but the files array beneath the
subdirs is empty.  I'm in way over my head here so if someone could bail
me out I would be eternally greatful!

Okay, let's go into :

This sounds exactly like how Cgiapp works, a class I ported from perl,
and available at:

http://freshmeat.net/projects/cgiapp/

Cgiapp is basically a do-nothing class that makes creating application
classes that work similar to how you describe very simple to code. Such
applications are then trivially re-usable, extensible, and customizable
(through instance scripts). And it provides all this in a mere
few-hundred lines of code.

I bring it up because you asked (a) if your setup is a good setup
(probably), and (b) how people in an OO world would achieve this
(Cgiapp).

You might check out the code and the docs to see if you can glean some
ideas for your projects.



(Man, I hate doing that... buy I *am* proud of that bit o' code, even if
it isn't completely original.)

We've been using it on a production server now for three weeks, and have
had no issues as of yet -- no segfaults, no memory leaks. It just
performs.

We're using GD to a small extent, and quite a lot of PEAR.

We've been using it in development since July 2004, and I've seen very
few issues. The only issue I have seen has been with overriding error
handling -- a few bugs we had created some cascading errors that ended
up segfaulting our systems, but those were probably errors of ours, not
of PHP's. (That's why they're _development_ servers, right?)

I'd say, go for it.

I believe you will have to establish stuff like this in the
constructor.  jsut create a function the same name as the class and it
will be run on object instantiation.  I had to do the a couple of years
ago for an array.

Check out the manual it used to explain this.

[PHP] Re: mail problem at interland

[Manuel Lemos]

Hello,
on 01/28/2005 12:09 AM David Edwards said the following:
I have a fairly simple script written that uses the mail() function on a 
client site hosted at Interland. I have used a similar script quite a few 
times before with no problem. However although the script generates no 
errors, no emails appear at their intended destination. Interland support 
has not been that helpful and they did suggest I try the '-f' option in the 
header. That did not work either. Has anyone seen this before, I am running 
out of ideas. The mail portion of the script is below:

$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-type: text/plain; charset=iso-8859-1\n";
$headers .= "X-Priority: 1\n";
$headers .= "X-MSMail-Priority: High\n";
$headers .= "X-Mailer: php\n";
$headers .= "From: $emailfrom\n";
$mailsent = mail($emailto, $subject, $msg, $headers,"-f" . $emailfrom);
The headers seem to be fine, except maybe for those priority headers 
that are useless and may be the cause of some spam filters understand it 
as a pattern of spam.

Other than that, you are not telling what exactly you are putting in the

Thanks Tom and Richard. 

No offense taken. The design isn't mine, I am "plugging in" to another 
system that expects a regex.

It is pretty easy to do with two regexps, one to check the length and 
another to see if there is a double &.  Would that work?  I don't know 
off hand how to do it with a single regexp.

If the design requires that every possible condition be checked with a 
single regexp then I would say, no offense intended, that the design is 
faulty.  Regexps are good tools but are not universal for all possible

Okay, how about that regex callback thingie thing thing, and you can use a
function that pretty much does: (strlen($1) < 42 && !strstr($1, '&&'))

That's not a valid JPEG.

It might be a valid JPEG encoded with base64, but browsers aren't gonna
display that correctly.

Or, maybe you should have been using base64_DEcode() to get the JPEG out
of the email, more likely...

That's a broken image icon.  When you finally get it right, it should
start with, errr, yoya or something like that for a valid JPEG.  Only the
o will have an umlat over it, I think.  I know it when I see it :-)

After that, you put the header back in, and it all works, unless it's
Internet Explorer which will ignore the changed header() -- because it
already cached it as non-image data -- so just quit and re-start to see it
as an image.

private $abc = 'test';

Now, if you NEED to use some kind of constant, you could write a PHP
script to create your class definition, and then you'd have what you
want...

That can't be too hard, since I once had a guy I was working for who
thought he had laid out a couple months' work for me, only I was done in 3
days, since it was all building classes to mirror MySQL table/fields in a
very brain-dead straight-forward fashion, and I wrote code like this, and
I don't even really grok PHP classes all that well.

Not that I think that made for a particularly good Design, but that's what
he wanted, so who am I to say?  But I sure wasn't gonna sit there typing
like a monkey when I could just script the same thing.

Or I guess you could hack something up with eval() if you really worked at
it...  That would be pretty nasty code, though, I think.

It would be nice if PHP allowed constants there, but it doesn't, so there
it is.

Thanks, Tom. I agree, but not an option at this time - other parts of the

This is an example of something that is easier to do (and probably

You mean only numerics? You can use ctype_digit():

http://php.net/manual/function.ctype-digit.php

I write more about the character type functions here:

http://shiflett.org/archive/84

There is also is_numeric(), if you want to allow any valid representation
of a numeric:

http://php.net/manual/function.is-numeric.php

Be careful with functions like is_int():

http://php.net/manual/function.is-int.php

They check the actual data type. If you're filtering data from the client
(POST, GET, or cookies), then it's going to be a string, even if it looks
like a number.

However, you can use an approach like the following to make sure something
is an integer:

   $testbody = base64_encode($testbody);
// header('Content-Type: image/jpeg');

Re: [PHP] Vars with flash

[Miles Thompson]

It ain't a dumb question, and is most easily answered by sending you to pp 
576 of Colin Mook's "ActionScript for Flash - The Definitive Guide". If 
you're doing a lot of Flash work this book is practically a "must have".

Are you using LoadVars class(Flash MX) or the LoadVariables  (Flash 4) 
method? I'll assume the former, as that's where your problem is addressed. 
Without doing a lot of typing, here's the relative bit, regarding 
formatting of variables transferred by load() or SendandLoad():
.
.
.
Any character that is not a space, a number (1-9), or an unaccented Latin 1 
letter (a-z or A-Z) is replaced as follows:
 - If system.useCodepage is false, the default, the character is replaced 
by one or more hexadecimal escape sequences of the form %xx, representing 
the UTF-8 sequence for the character. ...
.
.
.
And it goes on for another 3/4 page. Try Googling for "Flash 
System.useCodePage UTF-8" There are a number of combinations of conditions 
which the book addresses.

You can evaluate this yourself in Flash with
 trace(escape("é"));
which should display  %C3%A9 - two characters to PHP.  Feed that to PHP 
without some kind of transforming function and guess what you come up with!

Flash is encoding your string, PHP receives it, and  then translates it to 
what it knows/is working in. We were sending very simple date values, so 
the LoadVars class worked, but were receiving unpredictable text. For that 
we used the XML() class.

Have a look at http://ca3.php.net/manual/en/function.utf8-decode.php and 
other PHP functions associated with unicode. You will have a bit of futzing 
to do here.

Hope this steers you in the right direction - Miles

Hello everybody!
This might be a dumb question but i'm having a bit of trouble here:

I'm leaning towards Option 2*. What do you think? What other options do
I have?
I'd go with option 2 also.  Option one wouldn't really be less load, as 
it would be more for cron to parse, and pretty much execute the same 
amount of times.  Option 1 also brings into question security and 
access.  To add entries to the users crontab, your script would have to 
have permission to do so (suexec?), and giving it that much access could 
be dangerous.

I believe the default is to email to the username (on the local machine)
any output from that user's cron file.

But, if you're not READING the email on that machine as that username, it
don't do much good.

Or, if that machine doesn't have sendmail running to actually SEND the
email...

I have that on one machine, and keep forgetting to fix it, and then every
once in awhile have to go un-clog /var/mail/mqueue or whatever it is.

So I need a cron job to run sendmail every once in a while, I guess...

> I plan to add MAILTO to all my future cronjobs, it can help greatly when
> debugging.

I actually leave it on, so that if something BREAKS in my cron jobs, I
hear about it.

Got a whole email mailbox set up with filtering just to sort the cron jobs
into it.  Every day I delete the cron jobs that are "in progress" or where
I use the output to give me a status message of what's going on in the
long-term projects that are being fueled by cron.

Deleting an email is easy.  Knowing that a cron job suddenly stopped
working is very difficult, unless you got that email about it. :-)

Ideally, you write your cron scripts to produce *NO* output unless
something is wrong.  And useful debugging output when something does go
wrong.

Another Tip:
When things aren't working, use crontab -l to see the crontab, and then
copy paste the command and see what happens.

Oooh, and be sure you did 'cd' to be in your home directory before you do
that, just to be sure you have full pathnames everywhere.

WILD GUESS

It sounds like the phones are simply ignoring any image larger than X bytes.

Seems to me, then, that your best option is to set up your dynamic
resizing to down-sample, shrink, or color-reduce your image until it hits
X or lower for that phone -- maybe even all phones.

In other words, if your current script only gets an image down to 2X
bytes, have it call another script to be even more aggressive in shrinking
that image down -- Or iterate down through a series of changes until you
get the size down.

'Twould be nice if imagepeg() and friends had an imagejpegestimatedsize()
but you'll just have to play with imagejpeg and ob_start to capture the
size and find out if it's small enough.

Do phone users ever really want to download an image larger than X? 
Probably not.  So don't ask them to.

Actually, you might even want to create a special user with limited
access/ability (or just use 'nobody') and have THAT user handle all the
scheduler notifications et al.

Unless you *NEED* to have the scheduler doing things on that user can do
with the OS, it would be better to limit it to doing only what it NEEDS to
do.

Plus, you then just need one script to handle everybody, and need not
worry about changes to environment settings altering script behaviour, nor
permissions abuse, nor...

And, of course, it's probably going to be more efficient to run just one
script every five minutes that takes care of all scheduling tasks.

this works due to the superglobal $_SESSION; in order to use the $_SESSION
var (accessable everywhere without the use of global keyword) you must
first call session_start(), which in turn must be called before any output
is sent to the browser.
a quote from the following URL: (read it)
http://nl2.php.net/session
"
As of PHP 4.1.0, $_SESSION is available as a global variable just like $_POST, $_GET, $_REQUEST and so on. Unlike 
$HTTP_SESSION_VARS, $_SESSION is always global. Therefore, you do not need to use the global  keyword for $_SESSION. 
Please note that this documentation has been changed to use $_SESSION everywhere. You can substitute $HTTP_SESSION_VARS 
for $_SESSION, if you prefer the former. Also note that you must start your session using session_start() before use of 
$_SESSION becomes available.

What I found even more cool, at least for me, was that one could create
the ID3 data independent of the actual MP3 and then smush them together
on-the-fly.

So, like, I have this database on-line of who played which night at a
music venue, and then I have their MP3s encoded, but not tagged.

When you ask to hear a file, I snag the artist/title stuff and make the
ID3 tag, then push that out right before the MP3 stream.

Why?  Because I've got NO IDEA what the song titles are when I make the
MP3 (the night of the show) and the artists log in and input song titles
later.

So I'd have to re-encode the MP3 from .wav every time an artist gets
around to logging in and giving me the Title.  But the .wav isn't even
available at that point -- It's off-line on CDR only by then.

Oh yeah.  You can also throw in a small thumbnail of the artist before the
stream, which is pretty cool.

http://uncommonground.com/
has a radio station with files composed this way.  None of the MP3 files
have any ID3 info in them, really.  PHP/getID3 just lets me make it LOOK
like they have it.

NOTE: WinAmp doesn't support ID3 in streaming MP3s, only local.  G.

mail() will take care of that.

You might want to use \r\n instead of just \n, as that's what it's

Un*x-like boxes to use just \n...

You might want to add Reply-to: as well as From with the same setting to

What I would do at this point, if I were you, would be to take a step back
and look at the Design Goals that OO excels at achieving:

Code re-use, through inheritence of common behaviour
Modularization, through class segregation/API
Maintainability, through having objects that mirror real-world expectations
.
.
.

and see where and how you succeeded and where you need room for improvement.

My *personal* take would be that you've done an awful lot of coding, and
while you've got some of the benefits above, you're not really leveraging
the power of OOP all that much, and I'm wondering if you wouldn't be
better off with a structured procedural approach -- particularly since
your OOP code has led you down a path where you've got this big 'switch'
you don't care for at the heart of your code...

Just my skewed take on things.

YMMV

It's not that you can't use any variables at all -- It's that "$this"
doesn't make any sense in that context.

"$this" refers to the particular instance of the object you have created
with "new XYZ"

$xyz = new XYZ();
$xyz->bar();
When bar refers to "$this" it means the same as the "$xyz" instance.

If you are calling a static method XYZ::foo() then, really, there *IS* no
object inside of foo() to be called "$this" -- You didn't create an
instance of XYZ, so there is no instance to be named "$this" -- There is
only the class definition and the method.

It's an object that's not there -- more like the idea of an object without
having an actual concrete object to hang on to.

Hope that helps make sense of it all.

Hell, hope that's actually correct! :-^

Just Google for "PHP shopping cart" and you should find a ton of source
code, or a hundred carts you could just start using instead of
re-inventing the wheel.

Depending on configuration and settings, either:
http://php.net/file_exists
http://php.net/curl

Be aware that due to connectivity or dog-slow servers, you will get false
negatives fairly often.

You may want to record the existence with several checks spread out over a
few days before deciding that a URL truly doesn't exist.

With a slow server at the other end, that still won't be completely
reliable...

Also note that just because a URL exists, does not guarantee that it's any
good -- Domain name squatters and their link farms abound.

So you may also want to compare the actual output of the file with
expected results to see if it's valid or not.

This can get really complex really fast, as you might imagine.

Or you can use fopen() - http://us3.php.net/manual/en/function.fopen.php -

So basicaly they are saying that as the connection is hot closed at

more open connections concurently.  I guess its something that needs
checking with the ISP of the site in question.

I wouldn't say it has no bugs.. especially when you look at the other
5.0.x releases:

http://www.php.net/ChangeLog-5.php

Sure PHP 5 is getting better all the time, but "bug free" I seriously
doubt.  That said, I'm using it for new development and it does appear
to work fine.

you to 'hit' another server as if your script is a regular browser,
you can then check the returned headers to see if the page was found.

for instance my err.logfile (on my main dev server) is at 
/var/log/apache/error_log
admittedly all these paths (and cmdline crap in general) may seem daunting
at first - a few months hardlabor in a linux shell will have you

Honest.
That said, you should have only needed to change php.ini in a rather
obvious way -- but you need to re-start Apache after changing it, which
was probably what you missed.

redhat is shite, if you need professional support/indemnity/etc I would

Novell/SuSE. if you can go for a minimal setup like debian or gentoo (2 distros 
that
I like) which take the 'less is more' approach and gives you control - rather 
than
some redhat webserver 1500 miles away which thinks it knows better than you 
whether
you want to upgrade to the latest version of xyz.

Yes PHP5 is stable enough to use IMHO, just don't rely on updates to 
std packages always
working (like the redhat packages - which _ahem_ suck).

As before the systems guy will be doing it from source fk rpm's.
I pity the man - I have a friend who is _really_ ace at the sort of
thing and he used the word 'nightmare' (php5/apache2/firebird1.5 on a redhat
v3 enterprise server).
yum yum not. ()

(I have been writing a PHP5 framework since around 11-2003 and I 
haven't been able to
get it to segfault since around May last year.)

Yeh right interested what your view is on "framework"
framework == 'bunch of code that I can reuse to form the basis of a site'
basically its a data-object setup specific to Firebird DB - basically
you design a DB (day or 2), write the objects (day or 2 again), boom
instant CMS - and then I spend countless hours doing the custom magic for a 
given client.
There is a lot of work done on relating data entities and
on the generic/generated CMS interface. (3 types of relation: Reference, Vector,
Association - each is implements as a Field object - fields objects make up the
structure of data-object). Its pretty cool, but the stuff that really makes it 
stand
out (IMHO) is the generic management/editing screens...e.g.
1. highlight rows (ala phpmyAdmin but better) and then edit all the highlighted 
rows
(no use of checkboxes) with a single click
2. drag'n'drop columns (to change the order) with the ability to store the 
changes
(the system is capable of storing custom view settings for each user)
Actually I have wanted to make the code open source - but its really a
quite a complex beast to setup i.e. I can't just give someone a file and say
run it, theres your demo. which means I need to write an install file, a help
file and make a test DBstructure for people to play with as soon as I have
time I will get my ass into gear, then you (and the rest of the world) will
be able to see if its any good.


...so it runs on Apache2 quite nicely - there is the fact that you 
must use the prefork apache2
worker module, other than that there are no overwhelming problems (I 
assume that there
are bugs that could crop up - but this is just going on the assumption 
that bugless software
is only made on other planets :-) - at any rate I have pushed PHP5 
quite far on Apache2
and nothing is breaking - e.g. many cyclic-object-references, which 
was something that sometimes
caused segfaults in the 'early' days)

I think we could start a flame here, but I have been told the problem 
isnt with php c code directly but the c libraries it hooks into that 
instead thread safe ?
correct as far as I understand it. to paraphrase Rasmus (answering a post
on threading) 'your in uncharted territory, good luck'

Well umm, its a standard setup really, i install all the libraries

Not my decsision what would you suggest ? We need pretty standard stuff 
for it to be supported. I dont work for a web company, i'm in an IT 
department of a government Tv station or i wouldnt need to go through 
all this hassle to get it.


Yes PHP5 is stable enough to use IMHO, just don't rely on updates to 
std packages always
working (like the redhat packages - which _ahem_ suck).
As before the systems guy will be doing it from source fk rpm's.

(I have been writing a PHP5 framework since around 11-2003 and I 
haven't been able to
get it to segfault since around May last year.)
Yeh right interested what your view is on "framework"
...so it runs on Apache2 quite nicely - there is the fact that you 
must use the prefork apache2
worker module, other than that there are no overwhelming problems (I 
assume that there
are bugs that could crop up - but this is just going on the assumption 
that bugless software
is only made on other planets :-) - at any rate I have pushed PHP5 
quite far on Apache2
and nothing is breaking - e.g. many cyclic-object-references, which 
was something that sometimes
caused segfaults in the 'early' days)

I think we could start a flame here, but I have been told the problem 
isnt with php c code directly but the c libraries it hooks into that 
instead thread safe ?

how odd, i have assumed having a class static you could still throw around
classes cannot be defined as static - defining them as abstract has the

of being able to only use a given class statically (unless you subclass it and 
the subclass
is not abstract).
variables inside it, or its only meant to stay in the one static method so
yes you can use variables - but not member variables because $this is not 
defined in functions
that are declared static - bare in mind you can call a method statically even 
though its not
marked as static (just be sure you don't reference $this).
sidenote: the php4 trick of overwriting $this does not work in PHP5.
executing it like
Class::staticMethod();
and
Class::otherStaticMethod() ?
I don't really understand what your asking.

Heh is that for PHP5 or Apache2 ? I think PHP5 is stable enough for 
what i need it to do, no bugs hangs or crashes., Convincing others that 
it isnt bleeding edge anymore is a different story.

Dear friends,

we are looking for a RSS feeder implemented in php.

Is there anything good out there (something you have tried + tested).

Please, do not answer "do a google search", because I ALREADY know how to do
a google search. What we are interested is some feedback on real products
you have tested.

[PHP] Best way to execute actions within a class

[daniel]

I have been building a lightweight PHP4 based, hopefully PHP5 OO structure
where each page or php file contains its own class which is then executed
using the constructor like so

new SomeProject_SomeSubProject();


within the subclasses contructor I then call a method called start which is
in a base class called Page which is extended from the main project class
called SomeProject.

Within start it calls a method to check action page get uri's ie
?action=view , what i used to within procedural code is use switch
statements but seem taxing. Within this now will check if its a get or post
method and execute a method in the class with the same name ie public
function action_view() or if its a post method i have chosen to call it
post_action_view(). Now is this a good setup I would like some feedback on
how people in an OO world would achieve this.

Now that i have started executing constructors within the main page files, I
have come to think of better ways passing around a url possibly like
something like this

someurl/index/someproject_somesubproject/view

or

someurl/someproject_somesubproject/view

or

someurl/index/aliasofclass/view

or

someurl/aliasofclass/view

and for adding keys to the end for db stuff something like

someurl/index/aliasofclass/view?ID=1

or

someurl/index/aliasofclass/view/ID/1

i think then all u need is the main index.php file which works out which
class to load and execute ? And possibly peristist the objects loads too via
shm maybe ?

And if you need other files it could be like

someurl/otherfile/aliasofclass/view/ID/1

I'm sure this is all mod_rewrite stuff, is this taxing to do ?

Let me know always open to suggestions especially ways to do caching better.

1. you are calling the method on a object
