Don't know why the foreach is invalid?

 

<?php

    function curlURL($url) { 
        $curl = curl_init(); 
        curl_setopt($curl, CURLOPT_URL, $url); 
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
        curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2'); 
        $output = curl_exec($curl); 
            return $output; 
    } 
     
   $curlResults = curlURL("http://southcoast.craigslist.org/sss/"); 
   $pattern = '#<a href="(/[a-z]{3}/\d{10}\.html)">#';
   preg_match_all( $pattern, $curlResults, $matches);

echo "<pre>\n";
echo "Links:\n\n";
foreach ($matches[1] as $link):
   echo "\t" . '<a href="' . $link . '" target="_BLANK">' . $link . '</a>' . "\n";
endforeach;
echo '</pre>';


echo file_get_contents("http://southcoast.craigslist.org".$link);
$pattern = '#<sale-[a-z0-9]+-\d+@craigslist\.org>#';  //This is the attempted match for the email
preg_match_all( $pattern, $link, $matches);
foreach ($matches[1] as $address):

echo $address;
   $dbx= mysql_connect("localhost", "root", "");   //include before any database implematation
   if (!$dbx)
   {
      die('Could not connect: ' . mysql_error());
   }
   
   mysql_select_db("craigslist", $dbx);
   mysql_query("INSERT INTO `addresses` (`sale_items`) VALUES ('$address')");
      
   mysql_close($dbx);
endforeach;

?> 

When ever you're not sure that an array will contain what you think it will, you should do:

 

if(is_array($var)) {

    foreach...

}

 

To avoid that.

 

 

 

Anyway, yeah, your regexp is a bit off.

 

 

The first thing that I noticed is that you don't have any capturing parenthesis anywhere.

 

 

Trying putting () around what ever you're trying to extract.
