I'm trying to fetch the version number of PHP from a text stream. This is just a test for a structure I plan to use to fetch other data. The fact that I am fetching the PHP version out of a text file isn't the end goal but the way I'm trying to do it is. I'm using regex. My code snippet below only displays "PHP Version:" and not "PHP Version: 5.2.6".

My preg_match() function is not working correctly to pull the '5.2.6' value into my $out3 array. I would like to use this structure to also fetch non-digit strings as well so that's why I used .* in the capture section. But even that is not working!

PHP Code:

$view = "PHP version      5.2.6"; 
preg_match('/PHP version(.*)/smiU', $view, $out3); 
echo $out3[1].'<br>'; 
$phpVer = trim($out3[1]); 
echo 'PHP Version: '.$phpVer; 


and to also work with

PHP Code:

$view = "OS      Linux.CURRENT(Linux)"; 
preg_match('/OS(.*)/smiU', $view, $out3); 
echo $out3[1].'<br>'; 
$phpVer = trim($out3[1]); 
echo 'OS: '.$phpVer; 


Why do you use the U modifier?
Do you have any particular reason for it? Because I think it will work if you remove it.

The U (Unicode) was a left over I was trying. I removed it and it didn't make any difference. I'll keep working on this. Thanks...

In PHP, U is not the Unicode modifier. http://php.net/manual/en/reference.p....modifiers.php

My suggestion for a new pattern:

PHP Code:

'/PHP version(\s*)(.*)/i' 


Then, hopefully, $out3[2]='5.2.6'
