Get a string position with exec

[Rubble]

I have been going around in cicles and not getting any where. I need the LIB_VERSION_NUMBER in a variable ( I also need it padding to 8 numbers - in this case 06030401 but if the number was 6,3,4,11 it would need to be 06030411 but thats another problem ! )

If I use :

<?php 
echo "<pre>";
$test = system("convert -list configure "); 
echo "</pre>";
?>

I get the details below displayed ( I do not want it displayed ) it will also not be saved as a variable.

Path: C:\Program Files\ImageMagick-6.3.4-Q16\config\configure.xml

If I use :

echo "<pre>";
$test = exec("convert -list configure "); 
echo "</pre>";
echo $test; 

The value is input into the variable but the contents of the variable are just :

Not the whole thing.

I can not seem to get this to work; can somebody give me a pointer ?

can somebody give me a pointer ?

Sure.

exec

can somebody give me a pointer ?

Lol - you don't know how right you are.

Server() has a second, optional, parameter. This is a pointer (get it?) variable which will then store the return value.

e.g.

<?
Server("convert -list configure ", $output);
echo "<pre>".$output."</pre>";

preg_match('/^LIB_VERSION_NUMBER ([0-9,]+)$/m', shell_exec("convert -list configure "), $ver);
$ver = $ver[1]; 

$ver will contain only those numbers and the commas

I thought I had already tried something similar arkinstall; this found the information I wanted:

exec("convert -list configure ", $output);
echo $output[8]; 

Your method worked well longneck; better if I didn't know the location of my information in the array. It should always be in the same position but I will use your method in case it does change !!!

Thanks for the help.

Finished code:

// Select the version number from the configeration file
preg_match('/^LIB_VERSION_NUMBER ([0-9,]+)$/m', shell_exec("convert -list configure "), $ver);

$ver = $ver[1];

$number = explode( ",", $ver );

// Format the version from 6,3,4,1 format to 06030401
$version = "";

for($i=0;$i<4;$i++)
{
$version .= str_pad( $number[$i], 2, '0', STR_PAD_LEFT );
} 

// Depending on the version number either use font or type to display the available fonts
if ( $version > "06030507" ){
$font_list = "font";
}

else {
$font_list = "type";
}

echo "<pre>"; 
system("convert -list $font_list"); 
echo "</pre>";
