Wie "urlencode" in diese Function einsetzen ?

[Reimer]

Morgen,

ihr findet hier eine Function um aus einem Text alle URLs in Links umzuwandeln ( aus dem phpBB ). Ich möchte die aber die URL mit Hilfe von urlencode codieren. Leider sind bisher alle meine Bemühung gescheitert

Vielleicht könnt ihr mir helfen

function make_clickable($text) 
{ 

   // pad it with a space so we can match things at the start of the 1st line. 
   $ret = " " . $text; 

   // matches an "xxxx://yyyy" URL at the start of a line, or after a space. 
   // xxxx can only be alpha characters. 
   // yyyy is anything up to the first space, newline, or comma. 
        
   $ret = preg_replace("#([\n ])([a-z]+?)://([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]+)#i", "\\1<a href=\"\\2://\\3\" target=\"_blank\">\\2://\\3</a>", $ret); 
    
   // matches a "www.xxxx.yyyy[/zzzz]" kinda lazy URL thing 
   // Must contain at least 2 dots. xxxx contains either alphanum, or "-" 
   // yyyy contains either alphanum, "-", or "." 
   // zzzz is optional.. will contain everything up to the first space, newline, or comma. 
   // This is slightly restrictive - it's not going to match stuff like "forums.foo.com" 
   // This is to keep it from getting annoying and matching stuff that's not meant to be a link. 
   $ret = preg_replace("#([\n ])www\.([a-z0-9\-]+)\.([a-z0-9\-.\~]+)((?:/[a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+]*)?)#i", "\\1<a href=\"http://www.\\2.\\3\\4\" target=\"_blank\">[url]www.\\2.\\3\\4[/url]</a>", $ret); 
    
   // matches an email@domain type address at the start of a line, or after a space. 
   // Note: Only the followed chars are valid; alphanums, "-", "_" and or ".". 
   $ret = preg_replace("#([\n ])([a-z0-9\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)?[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret); 

   // Remove our padding.. 
   $ret = substr($ret, 1); 

   return($ret); 
}

http://www.php-resource.de/manual.php?p=function.preg-replace
/e modifier makes preg_replace() treat the replacement parameter as
PHP code after the appropriate references substitution is done. Tip: make
sure that replacement constitutes a valid PHP code string, otherwise PHP
will complain about a parse error at the line containing preg_replace().

am Beispiel des ersten replace:
preg_replace("#...#ie", "'\1<a href=\"\2://\3\" target=\"_blank\">'.url_encode('\2://\3'). '</a>'", $ret);

Ich würd allerdings htmlentities benutzen.
