[RESOLVED] extract url only

[hanpedro]

I want to extract url only from text data.
The $link_img has this data.
So I tried this code,

	$link_img = $list[$i]['wr_content'];
 	if (preg_match('#^http:\/\/(.*)\.(gif|png|jpg)$#i', $link_img, $tmp)) { 
	echo "<img src='<?=$link_img?>' align='absmiddle' width='91px' height='91px'>";
	}

But "echo" shows this data.

 "http://testserver1.com:8080/test%20messages%20and%20so%20on<br /><br /><div style="text-align: center"><img width="396" height="342" src="http://testserver2.com/photos/5186145181.jpg" alt="" style="border: medium none" /></div><br />test messages and so on <br /><br />"

Please let me know how to extract "http://testserver2.com/photos/5186145181.jpg" only.

Thanks in advance.

Note that this:

echo "<img src='<?=$link_img?>' align='absmiddle' width='91px' height='91px'>";

Makes no sense, you are in a php echo statement there is no reason to attempt to open PHP into another echo <?=. Also you are attempting put in the variable of the original text instead of using the match that was found.

echo "<img src='".$tmp[0]."' aligned='absmiddle' width='91px' height='91px'>";
