[jazzman121]

say i have a varable

$info

what i want to do is find any word begining with http:// and change it to a link by adding the code <a herf u know wat i mean

how do i do that?
i think i could use preg_replace but how do i use that funtion ?

[jazzman121]

its ok thanks anyways i found it out ... this code is good coz if some (smart html dude ) puts in the <a herf code it wont mess up the link by adding another <a herf


$txt = preg_replace( "/(?<!<a href=\")((http|ftp)+(s)?:\/\/[^<>\s]+)/i", "<a href=\"\\0\">\\0</a>", $txt );
