Zdar,
nemate niekto nejaky dobry regulerny vyraz pre sklikatelnenie adresy v texte?? Mne sa podarilo zostavit len taky, ktory bere do uvahy ten odkaz len vtedy, ak je prednim a zanim medzera.. Ale chcem tak, aby za nim mohlo byt zariadkovane, alebo aby mohol byt na samostatnom riadku..

teraz mam nieco taketo:

Kód:

$input = preg_replace("# http(s)?://([^, ]+) #"," <a href=\"http://$2\" target=\"_blank\">$2</a>", $input);
   $input = preg_replace("# www.([^, ]+) #"," <a href=\"http://$1\" target=\"_blank\">$1</a>", $input);

Ale nie je to to prave orechove

Miesto medzery daj \s, to znamena medzeru, tabulator aj novy riadok.

a ako konkretne mam toto pouzit?

Kód:

(http|https|ftp)\://([a-zA-Z0-9\.\-]+(\:[a-zA-Z0-9\.&%\$\-]+)*@)?((25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])|([a-zA-Z0-9\-]+\.)*[a-zA-Z0-9\-]+\.[a-zA-Z]{2,4})(\:[0-9]+)?(/[^/][a-zA-Z0-9\.\,\?\'\\/\+&%\$#\=~_\-@]*)* 

Tieto regulerne vyrazy su moja nocna mora

preg_replace("sem to dam","a tu?",$p)

Skús takto:

Kód:

$pattern = "/(http|https|ftp)\://([a-zA-Z0-9\.\-]+(\:[a-zA-Z0-9\.&%\$\-]+)*@)?((25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])|([a-zA-Z0-9\-]+\.)*[a-zA-Z0-9\-]+\.[a-zA-Z]{2,4})(\:[0-9]+)?(/[^/][a-zA-Z0-9\.\,\?\'\\/\+&%\$#\=~_\-@]*)*)";
$replace = "<a href='$0'>$0</a>";
$text = "bla bla bla odkaz bla bla bla";
$replaced = preg_replace($pattern, $replace, $text); 

Len neviem, či je ten regexp úplne najvhodnejší...

EDIT: resp. toto

Kód:

$input = preg_replace("#\shttp(s)?://([^,\s]+)\s#"," <a href=\"http://$2\" target=\"_blank\">$2</a> ", $input);
$input = preg_replace("#\swww.([^,\s]+)\s#"," <a href=\"http://$1\" target=\"_blank\">$1</a> ", $input);

To druhe je fajn, to prve mi vratilo nic - (samozrejme, premenne som spravne prepisal)

Da sa este taka vec spravit, aby mi to nemazalo zariadkovanie?

ked dam:

Kód:

bla bla www.nieco.sk

nieco

tak mi to zmaze zariadkovanie..

EDIT:
tak som sa este viac povrtal v phpBB zdrojakoch a nasiel som:

Kód:

function make_clickable($text)
{
   $text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $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, comma, double quote or <
   $ret = preg_replace("#(^|[\n ])([\w]+?://[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $ret);

   // matches a "www|ftp.xxxx.yyyy[/zzzz]" kinda lazy URL thing
   // Must contain at least 2 dots. xxxx contains either alphanum, or "-"
   // zzzz is optional.. will contain everything up to the first space, newline, 
   // comma, double quote or <.
   $ret = preg_replace("#(^|[\n ])((www|ftp)\.[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"http://\\2\" target=\"_blank\">\\2</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);
}

Funguje ! Dakujem moc za rady
