sorry for being such  a noob.. but how do i echo a users input and allow hyperlinking?? Right now if a person puts http://example.com somewhere in their message you can't click on it...thanks for any help

Just found this at the preg_replace() man.

function clickable($url){
        $in=array(
        '`((?:https?|ftp)://\S+[[:alnum:]]/?)`si',
        '`((?<!//)(www\.\S+[[:alnum:]]/?))`si'
        );
        $out=array(
        '<a href="$1"  rel=nofollow>$1</a> ',
        '<a href="http://$1" rel=\'nofollow\'>$1</a>'
        );
        return preg_replace($in,$out,$url);
    }

May be what you are looking for.

Ok, just gotta post this, this has got to be the easiest least frustrating way to do this..
<?php  function makeClickableLinks($text) {    $text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)',     '<a href="\\1">\\1</a>', $text);   $text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)',     '\\1<a href="http://\\2">\\2</a>', $text);   $text = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})',     '<a href="mailto:\\1">\\1</a>', $text);    return $text;  }

much easier than i expected!

sorry .... here it is
<?php  function makeClickableLinks($text) {    $text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)',     '<a href="\\1">\\1</a>', $text);   $text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)',     '\\1<a href="http://\\2">\\2</a>', $text);   $text = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})',     '<a href="mailto:\\1">\\1</a>', $text);    return $text;  }?>

to use - echo makeClickableLinks($text);

messy but you can figure it out

The problem with that function is eregi() is depreciated in PHP6. It is advised to use preg() functions instead, as they are not being depreciated.

Technically eregi is already deprecated (as of PHP 5.3) and will be removed as of PHP 6.0, but premisos' point still holds true. That being said it wouldn't take much to convert it to use preg_replace().
