PHP cURL fails to fetch images from website -


i've written small php script grabbing images curl , saving them locally. reads urls images db, grabs , saves file folder. tested , works on couple other websites before, fails new 1 i'm trying with. did reading around, modified script bit still nothing.

please suggest out for.

$query_products = "select * product"; $products = mysql_query($query_products, $connection) or die(mysql_error()); $row_products = mysql_fetch_assoc($products); $totalrows_products = mysql_num_rows($products);  {     $ch = curl_init ($row_products['picture']);     $agent= 'mozilla/4.0 (compatible; msie 6.0; windows nt 5.1; sv1; .net clr 1.0.3705; .net clr 1.1.4322)';      curl_setopt($ch, curlopt_header, 0);     curl_setopt($ch, curlopt_returntransfer, 1);     curl_setopt($ch, curlopt_binarytransfer, 1);     curl_setopt($ch, curlopt_useragent, 'mozilla/5.0 (windows nt 6.1; rv:2.0) gecko/20110319 firefox/4.0');     curl_setopt($ch, curlopt_ssl_verifypeer, false);     curl_setopt($ch, curlopt_verbose, true);     curl_setopt($ch, curlopt_returntransfer, true);     curl_setopt($ch, curlopt_useragent, $agent);      $rawdata = curl_exec ($ch);     $http_status = curl_getinfo($ch, curlinfo_http_code);     curl_close ($ch);     if($http_status==200){          $fp = fopen("images/products/".$row_products['productcode'].".jpg", 'w');         fwrite($fp, $rawdata);         fclose($fp);         echo ' -- downloaded <a href="'.$row_products['picture'].'" target="_blank">'.$newname.'</a> local: <a href="images/products/'.$newname.'" target="_blank">'.$newname.'</a>';     } else {         echo ' -- failed download <a href="'.$row_products['picture'].'" target="_blank">'.$row_products['picture'].'</a>';       }      usleep(500); } while ($row_products = mysql_fetch_assoc($products));

your target website may require/check combination of things. in order:

  • location. websites allow referer value (either site or no referer, prevent hotlinking)
  • incorrect url
  • cookies. yes, can checked
  • authentication of sort

the way sniff normal request looks , mimic it. msie user-agent string looks different genuine msie ua, however, , i'd consider changing exact copy of real 1 if you.

could curl output file (using setopt output stream) , telling error code getting, along url of image? me more precise.

also, 0 isn't success - it's failure
