I'm not getting any errors. It just isn't working.

code:
<?

$html = file_get_contents("http://www.yellowpages.com/fort-lauderdale-fl/acupunture");

preg_match_all(
    '/
<div class="listing_content">.*?
	<h3 .*?>
		<a .*?>(.*?)<\/a>
	<\/h3>
	<span class="listing-address adr">
		<span class="street-address">(.*?)<\/span>
		<span class="city-state">
			<span class="locality">(.*?)<\/span>,
			<span class="region">(.*?)<\/span>
			<span class="postal-code">(.*?)<\/span>
		<\/span>
	<\/span>
	<span class="business-phone phone">(.*?)<\/span>.*?
	<li><a href="(.*?)">/s',
    $html,
    $posts,
    PREG_SET_ORDER 
);


$listing=array();

foreach ($posts as $post) {
	
$listing['title'][] = $post [ 1 ]; 

$listing['street'][] = $post [ 2 ]; 

$listing['city'][] = $post [ 3 ];
  
$listing['state'][] = $post [ 4 ]; 

$listing['zip'][] = $post [ 5 ]; 

$listing['phone'][] = $post [ 6 ]; 

$listing['website'][] = $post [ 7 ]; 

    // do something with data
	
	echo  $post [ 4 ];
}


print_r($listing)


?>

If you see no errors, you should see an empty array being output - that means your regular expression is not matching.
You'll need to take it apart until you have something that does match, then readd and find the difference.

But honestly, a regular expression is not the right tool for this job (html can not be reliably parsed with a regular expression - you need a more powerful parser), and the one you sketched out is terrible sensitive to the whitespace between tags (and I'd bet even money on that that's also the reason it is not matching).

See http://stackoverflow.com/questions/3650125/how-to-parse-html-with-php for some suggestions on how to do this in a robust manner.

so long,
