Return false;
}
//Remove possible quotes on the URL connection
$url = preg_replace( '/(?:^[ '"]+|['"/]+$)/', '', $url );
if (!extension_loaded('sockets')) return false;
//Get url related information
preg_match( '/http://([^/:]+(:d{1,5})?)(.*)/i', $url, $matches );
if (!$ matches) return false;
$sock = socket_create( AF_INET, SOCK_STREAM, SOL_TCP );
if ( !@socket_connect( $sock, $matches[1], $matches[2] ? substr($matches[2 ], 1 ) : 80 ) ) {
return false;
}
//Relative address of the image
$msg = 'GET ' . $matches[3] . " HTTP/1.1rn" ;
//Host name
$msg .= 'Host: ' . $matches[1] . "rn";
$msg .= 'Connection: Close' . "rnrn";

$bin = '';
while ( $tmp = socket_read( $sock, 10 ) ) {
$bin .= $tmp;
$tmp = '';

$bin = explode("rnrn", $bin);
$img = $bin[1];

curl_setopt($hander,CURLOPT_FILE,$fp);
curl_setopt($hander,CURLOPT_HEADER,0);
curl_setopt($hander,CURLOPT_FOLLOWLOCATION,1);
//curl_setopt($hander,CURLOPT_RETURNTRANSFER, false);//Return data in the form of data stream, when it is false, it is displayed directly
