regular expression extract links / php / analytics question

Hi,
I'll be sending out a newsletter and i want to track clicks through GA. my idea is that i will grab all the links from the NL body and send them to a redirect script (with the GA campaign,source variables appended)
the reason that i will use this redirect script is becuase some of the links in the NL will be external sites.

is then a way with regular expressions to grab all the links and link text from a text block like :

<a href="link" title="linktitle"> linktext </a>
<a href="link" title="linktitle" class="xxxx"> linktext </a>
<a href="link" title="linktitle" target="_blank"> linktext </a>
<a href="link" title="linktitle"><img src="pathtoimage"/></a>



so as i can go something like


foreach($matchedlinks as $singlelink){
echo $singlelink->link;
echo $singlelink->linktitle;

}


Many thanks

 

preg_match_all('/<a title=".*?" href=(.*?)>/', $content, $matches);


I believe $matches[0] = the content of title=""
and $matches[1] = the url from href=""

had this lying around in one of my old scripts

 

cheers mate

can you tell me why the below is not working ?

$regexp = "/<a\stitle=(\"??)([^\" >]*?)\\1[^>]*\shref=(\"??)(http[^\" >]*?)\\1[^>]*>(.*)<\/a>/siU";

 

I'm sorry but I am not very good with developing regular expression maybe this will help you figure it out though:

<?php

$html = '
<a href="link 1" title="linktitle"> linktext </a>
<a href="link 2" title="linktitle" class="xxxx"> linktext </a>
<a href="link 3" title="linktitle" target="_blank"> linktext </a>
<a href="link 4" title="linktitle"><img src="pathtoimage"/></a>
';


if (preg_match_all('~<a\s+(?:.*?)href="([^"]+)"(?:[^>]*)>(.*?)</a>~si', $html, $links))
{
	$links = array_combine($links[1], $links[2]);
	
	foreach ($links AS $url => $title)
	{
		echo $title, ': ', $url, "<br />\n";
	}
}
else
	echo 'No links found';
	
?>

PHP:

... duplicate links will only show once.
