Curl

[Furedetsu]

Hi all,

I'm new to php but I have a problem with a remote connection to Google regarding SEO. Instead of fopen I would need to use curl. Can anybody give me the changed code for:

$file = @fopen($filename, "r");

	if (!$file) 
	{
		echo "<p>Unable to open remote file $filename.\n";
	}
	else
	{          
		while (!feof($file))  // load the file into a variable line at a time
		{
			$var = fgets($file, 1024);

          if (eregi($conditions,$var,$out)) // find the html code this SE uses to show the site URL
		   {  
           // highlight search terms within URLS 
				$out[1] = strtolower(strip_tags($out[1]));
           // Get the domain name by looking for the first /
           if (($x = strpos($out[1],"/")) !== FALSE)
           {
             if (strstr($out[1], "https"))
        	  {
     	       $x += 2;
     	       $x = strpos($out[1],"/", $x);
     	     }
           }
           else
            $x = strlen($out[1]);

           // and get the URL
				$url = substr($out[1],0,$x);
           $url = substr($url, 0, strlen($searchurl));
           $position++;

           // If you want to see the hits, set $showlinks_msn to something
				if($showlinks)
					  $siteresults[] = $url;

           // If the last result process is the same as this one, it
           // is a nest or internal domain result, so don't count it
           // on $real_position
				if(strcmp($lastURL,$url)<>0)
					  $real_position++;

				$lastURL = $url;

           // Else if the sites match we have found it!!!
				if(strcmp($searchurl,$url)==0)
				{
					$found = $position;
					break; // We quit out, we don't need to go any further.
				}
				else
           {

              if (strpos($searchurl, "www") !== FALSE)
                $search_alt = substr($searchurl, 4, strlen($searchurl) - 4);
              else
                $search_alt = sprintf("www.%s",$searchurl);

   				$url_alt = substr($out[1],0,$x);
              $url_alt = substr($url_alt, 0, strlen($search_alt));

         	   if(strcmp($search_alt,$url_alt)==0)
              {
					 $found = $position;
					 break; // We quit out, we don't need to go any further.
              }  
				}	               
			}
 			}
	}		 
	fclose($file);	

Thanks.

Replace

$file = @fopen($filename, "r"); 

With

$curl = curl_init();
      curl_setopt($curl, CURLOPT_URL, $filename);
      curl_setopt($curl, CURLOPT_HEADER, 0);
      curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
      $file= curl_exec($curl);
      curl_close($curl);

You'll need to rewrite your while loop

Hi there, thanks for your reply.
I was allready thinking in that direction and I knew that I had to change the while loop. I just don't fully understand how to do it.

Well, your !feof means while the end of file has not been reached and the fgets gets a line ... so I would change

while (!feof($file))  // load the file into a variable line at a time
              {
                  $var = fgets($file, 1024);

to

$lines = explode("\n", $file);
foreach($lines as $lineNum => $var){

which breaks the $file string into an array by newline characters and iterates each line.
