Removing part of text

[matfish]

Hi,

Im pulling a string (/maindir/subdir/index.php) from a database but need to remove the /maindir bit and leave with the rest, the code Iv got is just leaving me with index.php - any ideas? In another part of the site, I need to add /maindir to the beggining - also any ideas?

Many thanks

if you're wanting to remove the "/maindir" from the front of a string, just do this:
[code]
<?php
$String = "/maindir/subdir/index.php";
$String = preg_replace('|^/maindir|', '', $String);
echo $String;
?>
[/code]

if you're wanting to add it, just concatonate your string:
[code]
<?php
$String = "/subdir/index.php";
echo "/maindir" . $String;
?>
[/code]

hope this helps
