[SOLVED] Find and Parse URL

[jaymc]

I need to turn this

 

$mystring "This can be any txt at all but may contain a url like www.site.com of which needs parsing"

 

into

 

This can be any txt at all but may contain a url like <a href="http://www.site.com target=BlanK>www.site.com</a> of which needs parsing

 

I found the below php code in this section, but it only detects a urls presence within the string, doesnt actually do anything with it

 

if (preg_match('~
	(?:[a-z0-9+.-]+://)?  # A optional resource (http, ftp, etc)
	(?:\w+\.)+            # the host.domain
	\w{2,6}               # the TLD
	\S*                   # an optional path/to/file
	~ix', $mystring)) {
echo "no links, you turkey";
} else {
echo "nice comment";
}

 

If someone can help me with this I will be really happy! Driving me nuts!

 

If you want to go the extra mile, I need it in javascript aswell, but its more important php method works before anything else

[ToonMariner]

$str = preg_replace('/((ftp|(http(s)?)://)?www\.(.*)+\.(.*)+ /','<a href="$1">$1</a>',$str);

 

try that...

[jaymc]

Almost there..

 

Your code gives this

 

Warning: preg_replace() [function.preg-replace]: Unknown modifier

 

Hope you can rectify, I am useless at regex

[jaymc]

Any ideas guys?

[ToonMariner]

$str = preg_replace('/(((ftp|http|https):\/\/)?www\.(.*)+\.(.*)+) /','<a href="$1">$1</a>',$str);

 

 

try that

[jaymc]

Doesnt output anything, if I take the link out, it prints the text fine

 

Obviously a glitch in code

 

Here, best to use live example and modify until working

 

$str = "dss s sd s www.site.com but may not work";
$str = preg_replace('/(((ftp|http|https):\/\/)?www\.(.*)+\.(.*)+) /','<a href="$1">$1</a>',$str);
echo $str;

 

Hope someone can help

Any ideas?

This does the trick I believe:

 

<?php

$str = "dss s sd s www.site.com but may not work";

$str = preg_replace('/\b(?:[a-z0-9+.-]+:\/\/)?((?:www\.)(?:\w+\.)+\w{2,6}\S*)\b/','<a href="$1">$1</a>',$str);

echo $str;

?>

[jcd]

Er, looks like I put a stray www in there. Change to:

 

$str = preg_replace('/\b((?:[a-z0-9+.-]+:\/\/)?(?:\w+\.)+\w{2,6}\S*)/','<a href="$1">$1</a>',$str);

Great! That works perfect

 

Can anyone do that in javascript now?

 

Be amazing if could

Works fine with the above expression. Insert without the / at the start and end.
