cURL problem

[Ex1t]

I have this code

        $url = 'www.site.com'; 
        $list = array("ext.pdf", "ext_1.pdf", "ext_2.pdf", "ext_3.pdf", "ext_4.pdf"); 

        foreach($list as $lists) 
        { 
          $ch = curl_init(); 
          curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
          curl_setopt($ch, CURLOPT_HEADER, 1); 
          curl_setopt($ch, CURLOPT_URL, $url.$lists); 
          $result = curl_exec($ch); 
          curl_close($ch); 

          if (preg_match("/200 OK/", $result)){ 
              echo "<p>$url$lists</p>"; 
          } 
          else if (preg_match("/401 Unauthorized/", $result)) { 
              echo "<p>$url$lists</p>"; 
          }  

       } 

Now, if this script finds nothing i want to echo 'Not found'..
I can do it with 'else' but it displays 5 times..
I tried with exit() but there is also problem.. Help please

Use a variable to track if any files were found. It starts with the value false and you set it to true when you find the file. After the loop you check the variable.

Can you give me code for example?

Umm, well,

$found = false;

and then

// if found the file {
	$found = true;
// }

and then later

if (!$found) {
	echo "Not found";
}
