PHP Function: Make non linked links clickable

Recently I came across a problem making a twitter plugin. I needed to make links which had no “a” tag into links. You can do this progamaticly and here is the solution:

If you are going to use this script please download from here: links.php.txt

function makeClickableLinks($text) {

$text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_+.~#?&//=]+)',

    '1', $text);

  $text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_+.~#?&//=]+)',

    '12', $text);

  $text = eregi_replace('([_.0-9a-z-]+@([0-9a-z][0-9a-z-]+.)+[a-z]{2,3})',

    '1', $text);

return $text;

}

// Usage

// Email address example

$text = "you@example.com";

echo makeClickableLinks($text);

echo "

";

// URL example

$text = "http://www.example.com";

echo makeClickableLinks($text);

echo "

";

// FTP URL example

$text = "ftp://ftp.example.com";

echo makeClickableLinks($text);
