PHP Function: Make non linked links clickable

December 16, 2008

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

Code (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;
 
}
 
// 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);
