finding numbers in a string

hi all,
is there a simple way for extracting numbers from a string. i have a session array in which the data is like this "AB000121 --> nameof the client"
wherein i just want to extract "000121" where 0000121 could be any number from 0 to sky is the limit [just the numbers]... how can i do it?? :rolleyes:

Thanks in advance

Just use preg_replace()
<?php
$string = 'AB000121';
$newstring = preg_replace('/[a-zA-Z]/xms','',$string);
echo $newstring;
?>

Aerospace: Can you explain the use of xms in your preg_replace?

D.

You can look up these things yourself you know?
Trailing xms are three regex options
– x : Extended formatting (whitespace in regex is ignored)
– m : For line boundaries (and eliminates a cause of some subtle
bugs)
– s : ensures everything is matched by the "." symbol

Hi Aerospace,
the code works the way i want.
Just use preg_replace()
<?php
$string = 'AB000121';
$newstring = preg_replace('/[a-zA-Z]/xms','',$string);
echo $newstring;
?>

Thanks a lot :thumbsup:
