To me the salient point is, does java has as extensive a library or set of

Was PHP OOP-capable at the time? Perhaps the edu-bubble was simply looking down 
its nose at PHP. There being lots of courses proves nothing in and of itself. 
20 years ago, there were lots of PC mags you could buy, which caused some folks 
to say "look how much better the PC is supported than other platforms". Truth 
was, at the time, such support was needed given the mess of 640k limits, DOS, 
IRQs and the like, most of which issues have ceased to be relevant.

Anyway, why should one need a course to learn PHP, assuming you already know 
other languages. It's simple enough.

Which several rows? The row that will be updated is that (or those) that match

This one tells apache to recognise .php, .htm, and .html as suffixes of files 
that need to be sent to PHP. You probably don't want to remove that [1].

Dunno what this one does.

[1] But, having said that, realise that *all* files with those suffixes will be 
sent to PHP by apache, whether they contain any PHP code or not. Is that what 
you want? If I have an html file that contains some PHP code, I tend to use 
.phtml as suffix and so my AddType looks like:

 AddType application/x-httpd-php .php .phtml

You need to have your mysql_query *inside* the for loop. Then, what are you 
doing with the results of the mysql_query? Nothing?

Also, why do you need the for loop anyway? What is it supposed to do?

Because it's undefined. So is $pos. From what you've written above, both are 
local to includeXML. But neither is passed in as a parameter, nor is global. 
You can't initialise it within the function, it seems to me.

If $xml is supposed to be appended to and grown as you recurse up and down, 
then you have two choices:

1) Make them global
2) Pass both as extra parameters to includeXML

In both cases, each needs to be initialised before the first call to the 
recursive function

Solution (1)


$xml = '';
$pos = 0;// Presumably.
includeXML ($file, $locale, $url, 1);

...

function includeXML ($file, $locale, $url, $level = 1) {

global  $xml, $pos;

// stuff
while(($line = fgets($fp)) !== false) {
if($pos === false) {
$xml .= $line;
} else {
includeXML ('repository/' . $included, $locale, (int)$level
+ $pos - 1);
}
}
}

Solution (2)


$xml = '';
$pos = 0;// Presumably.
includeXML ($xml, $pos, $file, $locale, $url, 1);

...

function includeXML (&$xml, $pos, $file, $locale, $url, $level = 1) {// 
Note the & on the first parameter
// stuff
while(($line = fgets($fp)) !== false) {
if($pos === false) {
$xml .= $line;
} else {
includeXML ($xml, $pos, 'repository/' . $included, $locale, 
(int)$level
+ $pos - 1);
}
}
}


BTW it seems to me that you'll have the same problem with $included unless 
there's other code in includeXML that you've omitted.

You mean the script that processes the submitted page? No. Submitting causes 
your page to get replaced by the form's action, CRTP_Query.php in this case. 
Hmm, although it looks like you want a frame to receive the new page rather 
than replace the page. You'd probably need JavaScript to do that.

ISTM it's better for the user if, rather than reloading a whole page, you can 
get some bits of data from the server and use them to just alter the parts of 
the page that need updating.

Nothing to stop your OpenWindow() function doing a submit as in:

Submit


function OpenWindow (formPtr)
 {

 formPtr.submit ();

 }


Personally I never submit forms. I use ajax to communicate with PHP scripts and

I have a function that will take a comma separated string consisting of emails 
in these formats:

 "Soap, Joe" 
 Joe Soap  
 (Joe Soap) joe.s...@example.com

and turn them into a list where all the above examples are converted to:

 "joe@soap"@example.com

which I understand is also valid.

You are welcome to it if you wish.

That is explicitly documented here:



String access and modification by character

Characters within strings may be accessed and modified by specifying the 
zero-based offset of the desired character after the string using square array 
brackets, as in $str[42]. Think of a string as an array of characters for this 
purpose. The functions substr() and substr_replace() can be used when you want 
to extract or replace more than 1 character.

Just so. Perhaps those who are not grasping the point could re-read their copy 
of "The Elements of Programming Style" by Kernighan and Plauger where this sort 
of issue is covered.

See, it's all about expectations. When I worked at SLAC, there was a wise guy 
there who had removed the catalytic converter from his Scirocco and who though 
it clever to race up 280 from San Jose to SLAC at 100mph, sometimes 
slipstreaming behind another idiot doing the same. If I look in my rear-view 
mirror, I expect those I can see to be doing 70mph tops (that's what a lot of 
people did 30 years ago on 280), not 100, and to make judgements accordingly. 
Equally, I have certain expectations when I see a switch statement; it trying 
hard to look like if-elseif-etc is not one of them.

It may be an alternative, but it breaks the principle of least surprise. If I'm 
looking through someone's code, and I see a switch, I expect to see it used as 
Jim described. If the writer needs a different type of logic to make a 
decision, that is what the cascaded if-elseif-elseif construct is for, when the 
tests don't fall into a simple set-of-values choice.

The job of a programmer is not to be "clever" with a view to impress those who 
follow, but to achieve the desired outcome while at the same time making life 
easy for those who follow.

As has been pointed out you need switch(true).

That's a strange way of writing a switch, IMO. You should be using the if

Personally if I have a loop looking at filenames in a directory, I'll start it 
with:

while (something)
 {

 if  ($filename=='.' || $filename=='..')  continue;

 // rest of loop

 }


That way, the unwanted cases don't clutter up the logic for the cases I

Mmmm. There's the problem. Pascal doesn't *have* a return statement. In Pascal, 
implicitly, you return when execution reaches the end of a function. In fact 
the same is true of PHP and JavaScript, but in those languages you can return 
early just by saying return.

IMO, this is a major limitation of Pascal. I use returns wherever I feel like 
it - if I detect there's nothing more for the function to do, I return. Purists 
object to this; they say you should enter a function at one place and leave at 
one place. Well, that's a point of view. But more often that not it just leads 
to convoluted code in order to achieve that. The one time I *had* to use Pascal 
as that was the only option, I simply put a 999: label at the end of the 
function and did goto 999 wherever I wanted to do a return. Simples!

Here, the phrase "PHP manual" means:

  http://www.php.net/manual/en/

which I consider to be an excellent written resource for the language. In fact, 
I own no PHP books at all (whereas I do for JavaScript/HTML/CSS/SQLite) so that

is written in a straightforward way, not trying to be clever (unlike some

I assume that where you have "function filename" above, you really mean 
"function completeImageFilename".

Why do you think that the return you have coded above should give more than one 
filename when you've written "return $filename"? That's one filename. You then 
echo that out with your echo statement (because it's the return value of the 
function), and that's what you see. If you change the return to an echo, then 
instead of returning after once round your while loop, the while loop goes 
round and round dealing with each filename you have in $matches, and echoes out 
each one. When the while loop has completed, the function returns, but returns 
nothing at all. So your original echo then does nothing at all. And so you see 
the observed behaviour.

And so Dutch governments only last short periods of time, and it takes a long 
time to create a coalition. This is why Proportional Representation is such a 
bad idea. Better to have strong government with a clear mandate, and if you 
don't like it, vote it out next time.

By the way what does any of this have to do with PHP? Nothing, I think.

You could use ajax to request the information needed to load the second drop 
down. Once the user chooses their bank, then your JavaScript makes an ajax 
request to a PHP script that returns the clients list. You use this to populate 
the second drop down.

You don't need the nested echoes. Just concatenate instead:

echo '
   
   Subject of email:
   
   Body of email:
   "' . $text . '"   
   
   ';

In short you're doing this :

TW provided a popup list of your functions. It still helps to have them in 
alpha order though, for ease of navigation in the popup list.

[snip arguments]

I write functions to do specific things. E.g. I have a function (actually in 
JavaScript) called switchTab() which switches from one user view to another. 
It's just over 200 lines long and is mostly a giant case statement - and it's 
already loaded with function calls. I suppose I could break it up into five 
separate functions, more or less one for each case value, but then I'd have 
lots of unimportant local variables to pass around as argument values, and, 
what's worse, lots of unimportant functions cluttering the place up.

As was posted previously, you need to encode the query string. If you have:

   http://westeng/forum/store.php?id=Wiser Communication, LLC -& - Sprague Ave

that is going to be split in two unless you encode the "Wiser Communication, 
LLC -& - Sprague Ave" portion. I would do that with JavaScript on the html page.

This is not a PHP question.

[PHP] Parse errors

[Tim Streater]

After recently omitting a semicolon from the end of a statement, and having the 
result be a JavaScript error in an odd place, I'm trying to pin down just what 
PHP does with such errors. I made a small test script to run at CLI, which does 
some echoes and then, after that, I miss out a semicolon. On the command line, 
all I get is the parse error message with line number.

The script where I'd left the semicolon out of my production code is reached 
via AJAX, and sends some results back. It consists of a number of functions, 
then the main code appears, starting with two requires. The first such included 
file has some functions, puts out a header and does an echo, and calls 
set_error_handler. It's in the second included file that the semicolon is 
missed off (inside yet another function).

I would have expected that the results sent back would just consist of the 
Parse error: message, but for some reason the echo done in the first included 
file shows up as well (this is important as it frames the parse error message 
for me).

Is this the expected behaviour? The doc for set_error_handler says you can't 
use it to recover from E_PARSE and the like, and the function I supply to it 
doesn't appear to be called. I was just surprised that the initial echo 
statement's output made it back to the JavaScript side.

(I obviously don't expect to have parse errors show up in production, but 
having them nicely visible and logged during testing is useful)

On my first attempt to execute this, I'm getting:

  Missing argument 4 for my_func(), called in /path/to/source/file1.php at line 
556 and defined
  in /path/to/source/file2.php at line 3

Is this because $arg6 is passed by reference? There is some reference to this 
in the docs and the user notes but it's a little unclear. Or is there another 
reason?

Thanks,

Mmmm. Well, at this point I feel underwhelmed - but its entirely possible that 
I'm missing something profound [1]. After looking at some of the reviews of the 
book you mention on Amazon, I might be inclined to get a simpler intro.

[1] In June 1982 (or was it '83?) I visited PARC with a small group from SLAC. 
We saw the Star or whatever it was, with bit-mapped display and mouse pointer. 
Whoosh !! (Well, to be fair, we'd gone along to look into XNS).

While it is true that try/catch adds another level just like an extra 
if-then-else, there are times when it's unavoidable. During initialisation of 
my app, I have to check which of the files in a directory may be SQLite 
databases that belong to the app. So I have to check:

a) whether this file is an SQLite database
b) whether it has the two tables I expect to find there

Last time I checked the SQLite API in question, it looked as though try/catch 
was my only option.

I guess what I meant was, that I'd never have written it that way in the first 
place, so as an example it felt contrived. Amateurs or people with no training 
(in particular physicists at CERN 40 years ago) should be kept well clear of 
the goto. I'd probably write your function like this:

function val_nested ($name = null, $value = null, $is_mutable = false)
 {

 static $values   = array();
 static $mutables = array();

 if  ($name===null)  return $values;

 if  ($value===null)  return isset($values[$name]) ? $values[$name] : null;

 if  (isset($values[$name]))
  {

      if (!$val_is_mutable = in_array($name, $mutables))// Set existing 
value
   {
   $msg = 'The value "' . $name . '" is immutable and has already 
been set to ' . $values[$name] . '.';
   throw new Exception ($msg);
   }

  return $values[$name] = $value;

  }

 if ($is_mutable)  $mutables[] = $name; // Set new value
 $values[$name] = $value;

 return $value;

 }


I always add blank lines for clarity. Remove those and the above is 30% shorter 
than yours - as far as I could tell, none of the else clauses was required.

My approach is:

1) deal with the trivial and error cases first

2) deal with the real work next

Your val_nested() function looks like a straw-man to me. I've not used a goto 
since I stopped writing in FORTRAN in 1978, and not missed it [1]. Neither do I 
ever have deeply nested if-then-else - these are a good source of bugs. I 
suppose the rest of your article might have been dealing with simplifying 
val_nested() but TBH I wasn't interested enough to find out.

[1] Not quite true - a Pascal compiler I once had to use in 1983 lacked a 
return statement, so I had to fake it by putting a 999: label at the end of the 
function and goto-ing to that.

Well, that's going to be part of it, but it's never going to work if you open 
it via Explorer. If you do that, apache won't be involved whether it's running 
or not. This will only work if you have IE (or other browser) open and put 
http://localhost/your-webpage.html into the browser's address bar. Further, 
both the webpage and PHP file need to be in your document-root. Look in your 
apache config file for that).

You say:

   I opened the html file using IE 6.0

I don't like the sound of that. Do you mean you double-clicked the file and it 
opened in IE or do you mean you put Q:\... into the IE address bar or what?

What you should be doing is putting http://localhost/your-file.html in the IE 
address bar.

What is your document-root? Is the Q:\thingy part of it?

As I hinted in my previous mail, client and server side of my app are always on 
the user's machine. When the user starts the app, I create an apache config 
file on the fly and run an instance of apache just for the user. So I'm not 
messing with the standard OS X Web Sharing. For the same reason, I don't want 
to start modifying or creating a php.ini file.

Hmm, just looked more carefully at the docs. I see I'm going to have to add a 
prefs setting so the user can tell my app what timezone they are in. I find it 
odd that the OS can't provide this information.

Hmmm, looks like I haven't got one on my Mini. Which doesn't appear to matter

What I do seem to have is /etc/php.ini.default which I suppose you could rename

that the client and server aspects of my app (which will both run on the user's

  date_default_timezone_set (@date_default_timezone_get ());

Thanks, I expected that to be the case, but it's not been crucial up to now. 
Rather than having a script that runs for a while and quits, I'm hoping to run

Hmmm, I think perhaps I've not made myself clear - sorry about that. At present 
I'm using AJAX and apache; I'd like to *stop* doing that (and not use another 
web server, either). In my case, client and server are the same machine - the 
user's machine. There is a browser window and JavaScript within it which makes 
the AJAX requests. I just happen to use apache to have a variety of PHP scripts 
run to provide results back to the browser window.

At present these scripts generally are short-lived, but with some notable 
exceptions. Hence my exploration of whether I could use websockets instead.

That's what I'm doing - gathering information about bits of PHP that I've not 
used (or not used very much) before to see how my new setup could be structured.

I have a clear idea about *that*. I want to figure out if it's possible to use 
web sockets with a small server written in PHP to replace my current structure 
of ajax + apache + processes (which I suppose it forks). I see these benefits:

1) possible benefit - presumably when an ajax request arrives, a new process is 
started and so PHP has to be loaded and initialised each time. But perhaps this 
is in some way optimised so the PHP process is left running and apache then 
just tells it to read/execute a new script.

2) Definite benefit - when a browser makes an ajax request to run a script, it 
gets no information back until the script completes. Then it gets all of it. I 
have a couple of unsatisfactory workarounds for that in my existing structure. 
Websockets appears to offer a way for the browser to receive timely information.

I don't know what this means.

I do want to use it but would like to be able to replace it with a newer 
version. If there is no way to do this then that is a data point.

And here's another question. Can a child forked by pcntl_fork() use a socket 
that the parent obtained? Reading the socket stuff in the PHP doc, there are a 
number of user-supplied notes hinting this might be problematic.

[PHP] include

[Tim Streater]

At the moment I'm using an instance of apache to run PHP scripts, as and when 
required via AJAX. Having got some understanding of web sockets, I'm minded to 
look at having a small server to execute these functions as required. The 
scripts, some 50 or so, are only about 300kbytes of source code, which seems 
small enough that it could all be loaded with include, as in:



This appears to work although I couldn't see it documented.

I'd also like to be able to replace a module without restarting the server. I 
couldn't see a way to drop an included file, do I therefore take it that there 
is none? Failing that, is there a good way to dynamically replace parts of a 
PHP program, possibly using runkit?

[PHP] socket_recv

[Tim Streater]

I'm playing around with web sockets and have found a couple of simple servers 
written in PHP. They both appear to perform the initial handshake with a client 
but then just give up because socket_recv reports that there is no data. I'm 
confused by this as, the handshake being complete, I wouldn't expect there to 
be any data if the client hasn't sent any. Is there a way to wait with timeout 
on data showing up at a socket?

Here's what I would otherwise get:

Warning: date(): It is not safe to rely on the system's timezone settings. You 
are *required* to use the date.timezone setting or the 
date_default_timezone_set() function. In case you used any of those methods and 
you are still getting this warning, you most likely misspelled the timezone 
identifier. We selected 'UTC' for 'GMT/0.0/no DST' instead in /Users/tim/

[PHP] {} forms

[Tim Streater]

I'm looking at the source of a web sockets server and I see these various forms:

  "ws://{$host}{$path}"
  "HTTP/1.1 ${status}\r\n"

Are these simply equivalent to:

  "ws://" . $host . $path
  "HTTP/1.1 " . $status . "\r\n";

and if so, is there any particular benefit to using that form? Or if not, what 
do they mean?

(I've read up about variable variables).

Thanks,

Perhaps they just need to completely de-install the Acrobat plugin. When a PDF 
is in a Safari widow, there is a fade-in/fade-out
 type of array of things you can click on at the bottom of the window (not good 
UI, IMO, but there it is). You can choose to open in Preview, Save, or 
increase/decrease zoom. If you do nothing then the array fades out, but 
reappears if you mouse down there. As I say, I've not had, or needed, Acrobat 
Reader on a Mac for some 10 years. Trouble is, all these sites telling you to 
download this PDF and "needs Acrobat Reader" which is complete cock.

I have to say that I still really have no clue what you are talking about. Why 
would anyone with OS X want Acrobat Reader, when there is a perfectly good [1] 
application (note: application, not "feature") available that does the task 
just as well. And when the PDF shows up in Safari you can choose to view it 
there or open in Preview. I only do the latter if I intend to save the PDF, 
which is not always the case.

[1] Preview also allows me to adjust images when I can't be bothered to fire up 
Elements.

Well I'd rather it displays in the browser initially, which it does but not 
always (sometimes goes straight to disk). But if it shows in the browser window 
then there are buttons to save or open in Preview. I've not needed Acrobat on a 
Mac for years.

I think you posted an HTML-formatted email with images to this list. That is a

formatted as text-only. As it stands your mail made no sense at all.

No, as Dan has said. But if you have a file called wiggy, containing the 
following:

   #!/usr/bin/php
   

then you can run it at the command line by typing its name at the prompt - but 
wiggy will need to have execute permission set.

You can do a test yourself by hand. Go to www.ripe.net (one of the registries 
that allocates IP addresses). Click where it says: Ripe database. In the Search 
field type your IP address. Under Sources click on All. Under Types click on 
inetnum. Under Flags click on B (shows full details). Then click on Search, and 
scroll down to look at the results. You need to look at the inetnum object that 
contains the IP address of interest, then see Country.

Be aware that what this tells you is where an IP block is registered. Nothing 
to stop the entity using it from using those addresses anywhere on the planet, 
if it has its own network.

Sounds like you should also use a text editor rather that Word or similar for

I suppose my reaction is more like hmmm, interesting. I use globals here and

Well, there is an sqlite3 executable that one can run to do CLI things to a 
database. OS X comes with that and I was also able to download the source of 
that program, and the SQLite C amalgamation, and rebuild it myself. It is 
certainly possible, with that program, to execute a sequence of semi-colon 
separated statements. It *doesn't* work with PHP's PDO interface to sqlite, as 
I found in a test program I put together; I haven't properly tested that with 
the sqlite3 interface. I've tried asking on the sqlite general mailing list and 
(to me at least), the answers are at best unclear. There is a function, part of 
the C interface to sqlite, that talks about a sequence of statements, but I 
guess ultimately it depends on how the writer of the PHP sqlite3 interface 
implemented it.

That's the SQLite interface, though, rather than the SQLite3 one. The latter

I would like to use the SQLite3 (not PDO) interface to SQLite, and I would like

looks like a big mess of single and double quotes to me. Why don't you go

and fiddle until that works.
