remove character from string

[garethhall]

Hello,

If I had a string say

<?php

$exts = ".jpg,.gif,.psd,";

?>

 

How would I go about removing the last "," from the string? So I want it to read ".jpg,.gif,.psd"??

 

[PHPFreaksMaster]

something like this

$exts = ".jpg,.gif,.psd,";
echo substr($exts,0,strlen($exts)-1);

or if you need to remove only if "," on the end

 

<?php

$string = ".jpg,";

substr($string, -1) == "," ? $string = substr($string, 0, -1) : $string = $string;

echo $string;

?>
