Regex search function

[Wolphie]

Ok, so i'm trying to search google for specific keywords. However, clearly it's not working like i'd like it to, I'm not too sure what i've done wrong.

But, I want to return an anchor's href, and the name.

 

I.e.

 

<a href="[i want this]http://www.phpfreaks.com[/i want this]">[i want this]PHPFreaks[/i want this]</a>

 

This is what i have:

 

<?php
function search($str) {
	$reg = '~(<h2 class=r><a href="(.*?[^"])" class=l>(.*?)</a>.*?</h2>)~si';
	$val = 'http://www.google.com/search?hl=en&q=' . $str . '&btnG=Google+Search';
                $val = str_replace(' ', '+', $val);

	if(preg_match_all($reg, file_get_contents($val), $links))
		return array('anchor' => $links[3], 'href' => $links[2]);
}
?>

 

I want to be able to loop through them e.g.

 

<?php
$search = search($str);
foreach($search['href'] as $href) {
  echo '<a href="' . $href . '">' . $search['anchor'] . '</a>';
}
?>

 

Is this possible, and is there a better way? If so, could somebody provide an example please?
