RE: [PHP] variable variables

[scott [gts]]

there's one example of var-of-vars along with arrays below my rant


var-of-var is almost always an evil thing.  there are some
rare instances where they're necessary, but i assure you
that your script would be MUCH cleaner and easier to modify
in the future if you used a simple array.

compare: $value = $form[$temp . $i];
to: eval('$valueofsize = $'. $temp . $i .';');


$form['size1'] = "hey";
$form['size2'] = "there";

$size1 = "hey";
$size2 = "there";
$loopcounter = 2;

while ($i++ < $loopcounter) {
$temp = "size";
eval('$valueofsize = $'. $temp . $i .';');
print $valueofsize;
print $form[$temp . $i];
}

i'm not worried about speed of execution or actual

some typing and make my code a little clearer)

i think that using: $r = function() or return 0; is more
readable and easier on the wrists than the other two ways
and i'm looking for an equally terse way of accomplishing
the same thing with PHP

[PHP] How would you code: $r = func() or return 0?

[scott [gts]]

 
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I thought i'd ask for your comments on how you'd code this
common perl code with PHP:

$value = some_function() or return 0;

i usually code my functions to return 0 or "" on error, but
have to use the following code to handle it... neither seem
like a good solution to me.

this way decreses the readability of the code:
if (!$value = some_function)
return 0;

and this way adds an unnecessary if() statement:
$value = some_function()
if (!$value) {
return 0;
}

RE: [PHP] is_numeric for php3

[scott [gts]]

my understanding is that numeric is a broad term for 
number values (any value with only numbers and a 
decimal point) like 1, 5.6, 332, 0.5532, for example.

integers are a sub-set of numerics, so any integer is
a numeric value, but any numeric value is not
necessarily an integer.

$num=123 is an integer *and* numeric value.

$num='123' might not be an integer, but it is
a numeric.

now the problem of how to devise a proper test for
numeric values (without using regexps) is what i'd
like to see.

RE: [PHP] is_numeric for php3

[scott [gts]]

well.  sure, is_numeric() will work, but the point of the
exercise is to try and determine if a number is numeric
without actually calling is_numeric() or regexps.

personally, i think that regexps are swiss-army knives,
they can do almost anything -- i use them all the time,
although it took me a few months to fully understand them
and get over regexp-heebie-jeebies of my own.

RE: [PHP] Link Checker

[scott [gts]]

although it's a bit klunky (and not entirely correct) to do
things this way, but a simple fopen(); will tell you if
the URL is retrievable or not.

(although i dont think that fopen() handles redirects or any
of those esoteric HTTP features)

but if you want to make sure that a link is there, with
no SSL, redirects, or any other stuff, fopen() should
be more than sufficient.

RE: [PHP] is_numeric for php3

[scott [gts]]

i think he's asking for a numeric test, not an integer test.

your example looks like it should fail "3.50" (for example),
even though "3.50" is a perfectly valid numeric value.

personally, i think you should just use regexps. ;-)

i tried to write a little is_num() type function, but i kept
getting caught on split();  it seems that split() converts
everything to string, no matter what.  so if you try to split
on the decimal point of 45.67 ... you get two strings, "45" and "67"
not 45 and 67, so subsequent is_integer() calls fail 
(since is_integer() checks the *type* of the variable,
not the *value* -- very important to keep in mind)

here's what i came up with... perhaps it will be of some
help to you (even though it doesnt work)


function is_num($number) {

  // $x contains number, $y contains any decimal value
  list ($x, $y) = split("\.", $number);

  // if there's no decimal value
  if ( empty($y) ) {
return is_int($x);
  }
  else {
return ( is_int($x) && is_int($y) );
  }

}

RE: [PHP] The future of PHP

[scott [gts]]

:-)

for the type of sites that i develop (non-mission-critical,
non-financial), i find PHP's simplicity and elegance more than
offsets a lack of things like strong typing and a harshly
BDSM compiler (and whatever else Java/JSP has that PHP
doesn't)

for most websites out there, Java is probably overkill, and
using it would complicate the task at hand... but as with
everything in life, JSP/XML has it's place, and PHP has it's.

AFAIK, apache (at least) will honor this syntax and give
the arguments to the "index" file for the directory --
look in httpd.conf to find out what files are "index" files.

perhaps the problem with your script is that "index.php"
is not being loaded properly by apache (or does not exist)
etc. etc... (or perhaps you're not fread()ing enough of
the return data back into your script).

there could be a million things going on... but, as a first
step, take chris's suggestion and fully specify the filename
like so http://www.server.com/index.php?var=xyz

RE: [PHP] Having trouble with PHP exec function calling CGI program

[scott [gts]]

 
-BEGIN PGP SIGNED MESSAGE-

it could be that the webserver chroot()'s to some "secure" path,
and thus your script cannot find `date`.

perhaps all you have to do is to copy the binaries
that you need into the "safe" directory (if you can
first find out where the server is chroot()ing to)

if you think that your server is doing this, 
read up on "sandboxing", it might help you get a better
picture of what's going on.

look in httpd.conf to get the user name,
then chown the directory to that user

ex.

chown apache:apache ./dir/
chmod 755 ./dir/

and make sure that you change permissions to all
files that you write into the directory to be
read-write only (not executable),
chown 644 filename

and that you put newly uploaded files into a
directory *outside* the document root of your
webserver (so some random person cannot just
upload any random file to your server and have
immediate access to it)

RE: [PHP] regexps

[scott [gts]]

here are two regexps that might do what you want

"\w" matches alphanum (1-9a-zA-z)

IMO, the best way to check for non-alphanum chars is
to check for "\W" (upper case is negation of alphanum,
which will match only non-alphanum).



if (preg_match('/^\w+$/', $data)) {
print "entirely alphanum
}
if (preg_match('/\W+/', $data)) {
print "Contains non-alphanum!!";
}

RE: [PHP] Oh and one more thing

[scott [gts]]

it's a little bit complicated, but here goes.

1) format your harddrive
2) take out your motherboard and spraypaint it
bright orange.
3) dance around the desk three times holding the
motherboard above your head chanting
"mail mail, give me mail"
"date date, give me date"
"ga booga woooga shooga"
4) install linux 
5) install apache
6) install PHP

RE: [PHP] Q: Hiding Folder Directories from public while still...

[scott [gts]]

if you're using apache, there's a *much* easier/secure way
of doing this.

setup an .htaccess file to restrict access to certain
username/passwords.

check out both:
man htaccess
man htpasswd

RE: [PHP] How to Compare dates?

[scott [gts]]

it also appears that you're checking for the same thing
over and over and over

'0' is the same as "0"
and 00 is the same as 0
and "00" is the same as '00'

try checking for either 0 or "-00-00"

RE: [PHP] Installing PHP probs

[scott [gts]]

you dont have to have a server running.

just use the CGI binary.

...and if you're using windows - why not just use apache...
it's free, easier to install/configure than PWS (yech!)
and it has *MUCH* better documentation and support
than microsoft can ever offer.  :-)

RE: [PHP] Re: How can I make a Loading... screen?

[scott [gts]]

make the same window say "Loading"?

not unless you used DHTML to create an IFRAME
or DIV or some similar HMTL element (i havent
kept up on DHTML, so i dont know exactly what
you'd need to use).

set it to be the entire size of the browser
width and height = 100%, then, at the bottom
of the page, put in a javascript statement
to hide it.

i did something very similar to this once,
and i don't reccomend it.  it's a bad kludge...

but it does work, so definately check it out
if really want to have the "Loading" message
in the same browser window as the document
that's being loaded

my suggestion is to start with IFRAME, DIV, and FRAME
HTML elements and experiment.

RE: [PHP] How can I make a Loading... screen?

[scott [gts]]

use javascript.

put this at the top of your big document:
var waitwin = window.open( ... );

and this at the end:
waitwin.close();


you might have to double-check the syntax,
as i dont really use javascript too often,
but that should work fine.

RE: [PHP] Installing PHP probs

[scott [gts]]

it's a piece of cake for windows... two steps:

1)
download the .EXE and double-click on it
or
download the .ZIP and unzip it somewhere
  (usually C:\php)

2) configure & restart your webserver

if you download the .EXE it'll configure
any non-apache server for you.  if you use
apache, you'll have to configure a few
things manually.

read the README and INSTALL files and documents
and things... all the info you really need is
in the documentation...

RE: [PHP] Testing if Scripting has been disabled

[scott [gts]]

not at all.  the only kind of "scripting" that the
client controlls is client-side scripting.  browsers
do not have any control over server-side scripting.

PHP, Perl, C++, etc. are server-side.
Javascript is client-side.

if you disable scripting in MSIE, absolutely
nothing related with PHP will be affected, but
javascript will not work...

that's why i asked for a better definition of
your question - becuase "Scripting" can mean
so many different things.

PS: just remember that client and server are
completely separate.

RE: [PHP] SQL syntax error in PHP script. dunno what's wrong

[scott [gts]]

no offense to you sam, but please dont ever simply place
single quotes around values.  you have to escape the values
*themselves*.

what if someone submitted the form field title as:
$title = "'; DELETE FROM seminar; "

if you didn't escape the single quotes in there, it
would get interpreted as a valid DELETE statement
and your seminar table would get wiped.

however, if you escaped $title, you'd end up setting
title to "\'; DELETE FROM SEMINAR; " 
(rather than have the contents of $title interpreted
as SQL commands)

a lot of people send the reply to the list and

RE: [PHP] SQL syntax error in PHP script. dunno what's wrong

[scott [gts]]

*always always always* quote everything in SQL statements.
you run the risk of letting people insert arbitrary 
SQL statements into your script if you dont quote values.

if you're using MySQL, try mysql_escape_string
http://php.net/manual/en/function.mysql-escape-string.php

or you could roll your own with relative ease:

function db_quote($value) {
return "'". preg_replace("/'/", "''", $value) ."'"
}

RE: [PHP] Re: issues with __sleep() and __wakeup()

[scott [gts]]

i added a (hopefully helpfull) addition to the
online notes regarding magic-functions:
http://www.php.net/manual/en/language.oop.magic-functions.php

Here's what i posted, if anyone's interested:

Here is a sample class and some test statements to 
demonstrate how __sleep() is used. 

If you do not return anything from __sleep(), your 
object will *not* be serialized. You must return 
something from __sleep() to tell serialize what 
to serialize. 

svar['Hello'] = "World"; 
} 

function __sleep() { 
  $this->svar['Hello'] = "Yawn"; 
  // return list of instance-variables to be serialized 
  return array('error', 'svar'); 
} 

function __wakeup() { 
  $this->svar['test'] = "I'm here!"; 
} 

}// end class 
?>

name the buttons different things





then, even thought the form is posted to one place,
you can determine which button the user pressed by

RE: [PHP] writing while reading

[scott [gts]]

try only locking the file on a write, *not* on a read.
you are going to have many times more reads than writes,
even on the busiest day 

what you need to have is a blocking-lock your writes
and not bother with locks for reading.

the way you have it setup now, there's no locking
for writes, so you could definately have two instances
of PHP trying to write to the same file simultaneously
and corrupt your data.

besides, if you lock only for writing, and not for
reading, you can read the file while it's being written -
but you can never write twice.

so it seems that there's no way to specify *all* my

[PHP] references

[scott [gts]]

i've been reading over the docs on references, and i
can't see anyway to pass around functions as references.
i know how to do this easily with perl, but i cannot
seem to find the correct syntax for creating a reference
to a function in PHP.

what i'd like to do is something like this:

// X is now a reference to test() 
// but i dont want test() to be executed now
$x =& test();

// Now, i want to execute test() with 
// something like this and see "Hello World"
&$x();

function test() {
print "Hello World";
}

any and all help is appreciated.
thanks a lot.

[PHP] issues with __sleep() and __wakeup()

[scott [gts]]

I am having a problem with __sleep();
there mere existance of it is causing my object
to not get serialized at all.  __wakeup() works fine.

i am using PHP v4.0.6 / apache / win2k.

If i keep __sleep() in the object, it will not serialize,
but if i remove it, it serialized fine.  Does anyone
know why this happens?

Here's my object:

class Scott {
  var $svar = array();  // free-form hash for whatever data
  function Scott( )
  {
return $this;
  }
  function __sleep() 
  {
  }
  function __wakeup() 
  {
$this->svar['sleep'] = "I am waking up";
  }
}// end class


and now a test script

require_once('class.Scott.php');

$scott = new Scott();
$scott->svar['blah'] = "bacon";

print "object = ". $scott ."\n";
print "blah = ". $scott->svar['blah'] ."\n";
print "\n";

// serialize
$ser = serialize($scott);
print "serialized = ". $ser ."\n";

// trash the object
unset($scott);
print "unset object = ". $scott ."\n\n";

// unserialize
$scott = unserialize($ser);
print "object = ". $scott ."\n";
print "blah = ". $scott->svar['blah'] ."\n";
print "sleep = ". $scott->svar['sleep'] ."\n";

An actual "Question and Answer" FAQ is probably not
necessary, since there are so many other good

seems to be necessary is to provide newbies with
a current list of some really good PHP-related sites.

(like http://php.net/function -- i use it everyday,

RE: [PHP] Re: HELP!! What wrong with this code...

[scott [gts]]

or, if you're going to be dealing with a lot of data
that has lots of quotes in it, you could take the safe

lots of times, it's easier than escaping every single "

RE: [PHP] Question on Commercial Offerings

[scott [gts]]

and not to mention that almost any form of script protection
or source-code encryption can be broken with minimal effort...
you'd probably be wasting valuble time trying to protect your
scripts that you could better spend improving and maintaining
the code.

IMO: it's better to spend your time working on the script
itself rather than hiding the source code... you'll come out
with a better product in the long run - even if the occasional
person can duplicate your source for devious purposes. :)

RE: [PHP] Failure Configuring 4.0.6 on SuSE 7.1

[scott [gts]]

it seems that your 'lex' is in a non-standard place,
and cannot be found in your PATH.

make sure you have 'lex' on your machine, find out where,
then open up the Makefile and change it's path to lex
to the correct one.

RE: [PHP] fopen not opening url

[scott [gts]]

i wish i could help you out, but i tried your code (below)
and it worked perfectly... i'm running PHP Version 4.0.4pl1
on a Windows 2000 box.  perhaps it isn't the fopen() that's
failins.

$x =
fopen("http://p.moreover.com/cgi-local/page?c=Music%20business%20news&o=xml","r";)
or die("Cannot open!");
print fread($x , 4096);

[PHP] A good PHP auto-reply system

[scott [gts]]

Can anyone reccomend a good PHP (or perl) Web-based
email auto-reply thingy.

I work at a company that hosts websites and provides
POP email accounts, and i'd like to allow our clients
to come to our website, log into a "clients" section
and have more control over their service...

I'd like to allow them to specify email accounts as
"away" and provide a little "i'm on vacation" type
message, and a date range associated with that message.

anyone know of any *free* or cheap it's a SOSB
(small office, small budget) software that will
allow users to create an auto-away message?

If i dont find a nice one, i'll probably end up writing
my own... but i'd prefer to save myself the work of
reinventing the wheel if i could possibly find a good
free one and work on hacking the code for my own needs.

RE: [PHP] Making php execute php

[scott [gts]]

It's failing becuase $abc is not valid PHP code, but is HTML.
to get eval to work correctly, only pass it valid PHP code.

This will print "Hello World";

$abc = '
print "$Message";
';

$Message="Hello World" ;

eval ($abc) ;


If you want to output HTML, enclose it within
a print "" statement, or something similar.

RE: [PHP] Need help with formatting time

[scott [gts]]

This will convert minutes to hours, then convert
to 12-hour am|pm based time.   all hours have 60
minutes.  it's simple mathematics to convert.

$m = 780;
$h = 0;

// convert to hours:minutes
while ($m >= 60) {
  $h++;
  $m -= 60;
}
print "$h:$m \n";

// convert to 12-hour am|pm 
if (!$h) {
  $suff = "am";
  $h = 12;
}
elseif ($h == 12) {

RE: [PHP] submitting free-form text to a database

[scott [gts]]

for the quotes thing.  you must have single quotes around the
values that will go to the database, and you must escape single
quotes inside the value with either "''" or "\'" (at least in 
MySQL, both work)

and as for the database... IMO, you should download MySQL now and
save yourself a ton of trouble porting/updating code later on.

MySQL is free, fast, good, stable, etc.  Everything i hear about
Microsoft databases leads me to believe that they're buggy, slow,
and incompatible with most other databases.  

if you write the entire thing for MS-access, you'll probably have
to re-write half the database access code when you decide to
switch to MySQL... so better to do it sooner than later and save
yourself the work down the road.  :-)

RE: [PHP] RE: string search

hehe... that's what regular expressions are for.
they're extrememly powerful... but that doesnt mean that
you should only use them for extremely complicated situations.
they work great everywhere... 

if you dont like "overdoing it", you might as well loop
thru the string character by character, C-style.  :-)

To do what you want, throw a loop statement around the preg_replace

even numbers are even becuase they're divisible by 2
w/o a remainder... use this property to your advantage:

if ( $num % 2 ) {
print "$num is odd";
}
else {
print "$num is even";

RE: [PHP] RE: string search

[scott [gts]]

read the docs for ereg... i hardly use it, so i dont know
for certain if it will match. (althouth the use of "^" at
beginning *and* end suggests that it wont do what you expect)

preg will match "aol.com" with this regexp:

preg_match('/aol.com/', $string )

RE: [PHP] echo vs printf

[scott [gts]]

from the manual:
[print is a language construct [EMAIL PROTECTED]]
The print() function returns a boolean indicating the status of the call. If the
write was successful, print() returns 1. If not, it returns 0. This can be used to
detect when the client has closed the connection, and appropriate measures taken. The
builtin echo does not provide this same service.


can anyone else think of any other difference between
print and echo ?

i use print, becuase that's what i'm used to...
but i'd be curious to find out if there really
is any significant differences between the way
echo and print both work.

RE: [PHP] sessions . . . .

[scott [gts]]

any number of things could happen to the $directory variable...
it could be out of scope, gotten overwritten or unset by another
function, or it might just never have been saved to the database...

but the real problem with that code is that there are no 
error checks on the file functions.  that is a bad thing.

you should *always* check file operations for errors.
$fp = fopen( ... ) or die("Cannot open");

you are basically describing the "use strict;" pragma of perl.

if you declare "use strict;" at the beginning of a perl script,
you must then declare all variables before using them (among
other things that "use strict" prohibits, but variable declaration
is by far the most noticeable effect of "use strict")

my $num = 5;#good

$num = 5;   #error

but the great thing is, is that you can turn "strict" mode off
for specific code blocks if you find a need to get a little
loose with the rules.

no strict;
$x = 5; #no error


i wish PHP had an equivilent to perl's "use strict"... 
it would certainly save us all a lot of time, and probably
make us clean our code up a little bit :)

> I do not believe that this would sacrifice very much freedom in the

if PHP make variable declaration an optional thing by use of
something similar to perl's "use strict" pragma, then it wouldnt
sacrifise anything... becuase only people who wanted it would
use it.

if PHP were to mandate variable declaration for all scripts all
the time, then it would certainly sacrifise a lot... 

>
> Does anyone else have any thoughts on this?>

yes.  i love the idea... just as long as it's an optional feature
that can be turned on and off as the programmer needs.

i guess you've got a more recent version of PHP than i do...

For me, it prints out "This is printed" but not

after reading thru the PHP site some more, i found a little
note mentioning a problem with the way negative integers are
handled in v4.0.6...

what version are you using?
what do you see when you run this code?

if (5 < -2147483647) {
print "This is printed.";
}

if (5 < -214748364) {
print "This is not.";

RE: [PHP] session problem using headers

[scott [gts]]

you're passing the PHPSESSID incorrectly, it seems

you must do something like this:
  
or
  header("Location: nextpage.php?$SID");

what you're doing now will go to page "input.php?=SID"
instead of "input.php?938sa9fa98f7daf987a9s" (or similar)

be *extremely* careful.  eval() is like spawning another PHP

people could type in unlink(); and such commands and really

[scott [gts]]

no offense, but that's a bad kludge for the problem.

however, if you really want to do that, you could try
checking $SERVER_NAME and $HTTP_REFERER and other
enviornment variables like that... 

what would be easier (and better practise) to do is to 
verify that the incoming username is valid...

RE: [PHP] Re: How to maintain a variable between PHP pages (sessions?).

[scott [gts]]

sessions or cookies is the way you probably want to go.

you could pass the variable around to each and every
form, but that is a pain in the ass, and extremely
prone to errors.

on the first page, where you check the user's ability to 
use attachments, you could simply set a cookie

setcookie('cookie_can_use_attachments', ... );

and on subsequent pages, check to see if the variable
$cookie_can_use_attachments is set

or, if you plan to carry arounc more information from
page to page than just the user's ability to use attachments,
sessions will make your life much easier 

best of luck.

what do the tags look like?

the first is a short tag
the second is an asp style tag

RE: [PHP] The need for strong typing...

[scott [gts]]

you could easily write yourself a typing function to take
care of all that (as someone suggested previously) using the
same familiar syntax as you want to use in the function
definition.

function pay($fromaccount, $toaccount, $amount, $memo) {

  $good = checkInput($fromaccount, "int", $toaccount, "int", $memo, "varchar(1000)" )
or die("Invalid input!");

  // code...

RE: [PHP] Strong typing?

[scott [gts]]

and as far as i know, perl's 'strict mode' has absolutely
nothing to do with typing of variables...

use strict; will force you to define all variables
with "my $var;" or "local $var;" before you assign values
to them or try and use them... but it doesnt do anything
about enforcing typing... 

in perl 6, i think that plans are under way to add
extensions that will let people strongly-type
variables if they want (but it still wont be mandatory)

example: my integer $number = 5;

would stronlgy-type that variable as an integer, and
you wouldnt be able to assign any other type of value
to it without an error.  but i dont know how far the
developers will go towards realizing strongly-typed
extensions to perl... 

as rasmus said... it's incredibly hard to have it both
ways.  the freedom of perl and PHP largely comes from
*not* having to always worry about variable typing,
memory allocation/cleanup and all those other nitpicky
low-level things that BDSM ... errr C programmers
seem to love  :-)

RE: [PHP] Thumbnail Generation from DB Stored Images.

[scott [gts]]

Here is my code to turn a directory full of *files*
into thumbnail images.  im sure you can adapt it to
your own needs...  the code is a bit long-winded, but
it was my first attempt at writing thumbnail code,
so forgive me ;)



// example call to the function
make_thumbs('./pictures/cavern/', './pictures/cavern/thumbs', 200, 60 );

/*
Simple function to make thumbnail images for an
entire directory of .JPG images. (no GIF support
because the owners of the GIF patent are buttheads)

It will create square thumbnail images (height=width),
with the original image resized properly within the
thumbnail dimensions to preserve the height to width ratio

This code is free for use as long as you keep my
email and URL in here:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
http://furt.com/code/make_thumbs/

Syntax of function call
  make_thumbs(
$dir= where the original image files are located
$tdir   = where you want the thumbnails to be saved
$max= $max=width=height of the new thumbnail images
all thumbnails are square.
$quality = quality of thumbnail JPG worst(1..100)best
$border  = how many pixels of border to put around the image
);

*/
function make_thumbs($dir, $tdir, $max, $quality=75, $border=3) {
  // this is so the script won't time out
  set_time_limit(0);

  $files = opendir($dir) or die("Cannot opendir $dir");
  while ($file = readdir($files)) {

if ( preg_match("/[a-zA-Z0-9]\.(jpg|jpeg|JPG|JPEG)$/", $file) ) {
//if (!file_exists($tdir .'/'. $file .'_t.jpg')) {

// Information about the original image
$img_name = $dir .'/'. $file;
$img  = imagecreatefromjpeg($img_name) or die("Cannot read 
$img_name");
$img_x= $img_y = 0;
$img_w= imagesx($img);
$img_h= imagesy($img);

// Create a new empty container for the thumbnail image
$out = imagecreate($max, $max);

// Set background colour of the thumbnail container
$bg = ImageColorAllocate($out, 200,200,200);

// If image is more wide than tall
if ($img_w > $img_h) {
$mod   = ($img_w - $max) / $img_w;

$out_w = $max;
$out_h = $img_h * (1 - $mod);

$out_x = 0;
$out_y = ($max - $out_h) / 2;

$out_x += $border;
$out_w -= $border*2;
}

// If image is more tall than wide
else {
$mod   = ($img_h - $max) / $img_h;

$out_h = $max;
$out_w = $img_w * (1 - $mod);

$out_y = 0;
$out_x = ($max - $out_w) / 2;

$out_y += $border;
$out_h -= $border*2;
}

// for debugging purposes... so i can see what's going on
//print "out_x=$out_x, out_y=$out_y, img_x=$img_x, img_y=$img_y\n";
//print "out_w=$out_w, out_h=$out_h, img_w=$img_w, img_h=$img_h\n";

//Put some text into the image
//$fg = ImageColorAllocate($out, 0,0,0);
//imagestring ($out, '2', 3, $max-15, "Text", $fg);

// Copy and resize the original image into the new thumbnail container
imagecopyresized (
$out, $img,
$out_x, $out_y, $img_x, $img_y,
$out_w, $out_h, $img_w, $img_h);

// Save the image to disk (in the thumbnail directory)
imagejpeg($out, $tdir .'/'. $file .'_t.jpg', $quality);

RE: [PHP] installation

[scott [gts]]

the RPM is a binary.  if mysql support is not in the RPM,
there's no way to add it

if you want to install PHP the simplest way, get the
sources and compile it yourself as a stanalone binary
(NOT using --with-apache or --with-apxs)

then you can tweak it however you want, and compile
in support for whatever you need... 

Here's the quick way of doing it:

1) download mysql, unzip it.
2) download PHP ,unzip it
./compile --with-mysql=/path/to/mysql   and other options
make
make test
make install

3) edit apache httpd.conf
4) restart apache

done.   :)
