Regex-get integer between tags

[rupam_jaiswal]

Hi,

Please excuse if similar issue has been posted earlier.

My data is like

 

I am going [ABCDEF]123[/ABCDEF] to movie.

I want a regex to get the value between [ABCDEF] and [/ABCDEF] only if its integer.

eg if its [ABCDEF]junk characters[/ABCDEF] then I dont want...but if its [ABCDEF]123[/ABCDEF]

then I require 123

 

Regards

<?php
$str = 'I am going [ABCDEF]123[/ABCDEF] to movie.';
preg_match_all('~\[ABCDEF\]([0-9]+)\[/ABCDEF\]~', $str, $matches);
echo '<pre>' . print_r($matches[1], true) . '</pre>';
?>
