if text exists dont show it

[mysterbx]

Hello, is it possible to not show the text if it already exists in the petern?

 

Example:

 

$text= "Here is your download link:
http://example.com/download1.exe
http://example.com/download2.exe
Or you can use this one (the same)
http://example.com/download1.exe
http://example.com/download2.exe";

 

Output(response from a simple script)

http://example.com/download1.exe
http://example.com/download2.exe
http://example.com/download1.exe
http://example.com/download2.exe

 

Response from the script I am looking for:

http://example.com/download1.exe
http://example.com/download2.exe

 

No same links shouldnt appear in the output or "echo"...

 

it should be possible?

oh, btw im usig this

preg_match_all("#(^|[\n ])([\w]+?://[^ \"\n\r\t<]*)#ise", $htmlbody, $links);
foreach($links[2] as $link) echo "$link

 

to search for http links in the text...

If you put

 

$links[2] = array_unique($links[2]);

 

before your loop that should remove any duplicate values.

yet again... it works! 

 

10x again...
