Preg_Replace

[ajicles]

I have a problem, I want to use PHP to search through a variable and take the text and make it into <a href> click-able link. But the only thing is there is a lot of other things inside of the same variable.

 

I could use this but, it just only works with one thing in the variable:

 

<?php

function clickable_link($text)
{

$text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $text);

$ret = ' ' . $text;

$ret = preg_replace("#(^|[\n ])([\w]+?://[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $ret);

$ret = preg_replace("#(^|[\n ])((www|ftp)\.[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"http://\\2\" target=\"_blank\">\\2</a>", $ret);

$ret = preg_replace("#(^|[\n ])([a-z0-9&\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)*[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret);

$ret = substr($ret, 1);
return $ret;
}
$text="www.google.com";

echo clickable_link($text); 
?>

You want to expressions to be greedy.

Huh? With  $text="www.google.com is fun. ftp.goobar.com is not.  http://link.me for short links!"; all three are wrapped in anchor tags as expected.

I could do this but I would have to make custom tags like <link> </link> and echo back the url. But with a chunk of text I would have to search for the beginning of http and follow that to the end of the url. Something like:

preg_match('%http://(.+?) %s', $data, $matches);

 

and the space after the url ends the link which would be proper? I'll try this and get back to you.

I tried using:

 

<?php
$data = "

preg_match('%http://(.+?)
%s', $data, $matches);

echo $matches[1];
?>

 

Still trying to figure this out. I use from http:// to a line break but I was wondering if I could use a for statement to get all the of the urls..
