    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

    Here you go:

    The regex: #^\[ABCDEF\]([0-9]*)\[/ABCDEF\]$#

    <?php

$data = <<<DATA
[ABCDEF]123[/ABCDEF]
DATA;

if(preg_match("#^\[ABCDEF\]([0-9]*)\[/ABCDEF\]$#", $data, $matches)) {

print($matches[1]);

} else {

print("No matches found");

}

?>
    PHP:
    [ABCDEF]123[/ABCDEF] = is valid

    [ABCDEF]junk characters[/ABCDEF] = not valid

    If you have a multitude of these patterns in your data, remove the ^ and $ from the pattern above and use the preg_match_all() function
