I need to take something out of a variable and I dont know how.
I have

XXXX
How would I go about taking the project_ out of it?

if the first part of the variable is always the same (ex: 'project_'), you can do a substr() call to get the remainder.
ex:
Code: Select all
<?php
$id = 'project_XXXX';
$id_sub=substr($id,8); // $id_sub='XXXX'
?>
On the other hand, if the first part of the $id can be variable ('project_', 'dept_', etc) but contain a common character separating the parts ('_'), use split(), explode(), or preg_split()
Code: Select all
<?php
$id1 = 'project_XXXX';
$id2 = 'dept_YYYY';
$id1_parts=explode("_",$id1);
$id1_sub=$id1_parts[1]; // $id1_sub='XXXX'
$id2_parts=explode("_",$id2);
$id2_sub=$id2_parts[1]; // $id2_sub='YYYY'
?>
