PHP make_clickable
So you have string that contains URL’s and you want to make them “clickable”. This is simple and it works:
function make_clickable($text)
{
return preg_replace('@(?<![.*">])\b(?:(?:https?|ftp|file)://|[a-z]\.)[-A-Z0-9+&#/%=~_|$?!:,.]*[A-Z0-9+&#/%=~_|$]@i', '<a href="\0">\0</a>', $text);
}
Supports normal, ftp, file and email URL’s as well as subdomains. Also it doesn’t mess with HTML a tags that already exist in the string.
