There are two ways to get remote pictures in PHP: CURL method and sockets method to get remote pictures_PHP tutorial

Method 1: sockets

Copy code The code is as follows:

$a = "http://jb51.net/content/ uploadfile/201106/thum-f3ccdd27d2000e3f9255a7e3e2c4880020110622095243.jpg";
$local = 'socket1.gif';
$aa = getImg($a,$local);
/*
*@ Complete Image address
*@ File name to be stored
*/
function getImg( $url = "", $filename = "" ) {
if(is_dir(basename($filename))) {
echo "The Dir was not exits";
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";
socket_write( $sock, $msg );
$bin = '';
while ( $tmp = socket_read( $sock, 10 ) ) {
$bin .= $tmp;
$tmp = '';
}
$bin = explode("rnrn", $bin);
$img = $bin[1];
$h = fopen( $filename, 'wb' );
$res = fwrite( $h, $img ) === false ? false : true;
@socket_close( $sock );
Return $res;
}

Method 2: curl

Copy code The code is as follows:

$url = "http://jb51.net/content/uploadfile/201106/thum-f3ccdd27d2000e3f9255a7e3e2c4880020110622095243.jpg";
$filename = 'curl.gif';
//http://jb51.net
getImg($url, $filename);
/*
*@Get the specified image locally through curl
*@ Complete image address
*@ File name to be stored
*/
function getImg($url = "", $filename = "") {
if(is_dir(basename($filename))) {
echo "The Dir was not exits";
Return false;
}
//Remove possible quotes on the URL connection
$url = preg_replace( '/(?:^['"]+|['"/]+$)/' , '', $url );
$hander = curl_init();
$fp = fopen($filename,'wb');
curl_setopt($hander,CURLOPT_URL,$url);
curl_setopt($hander,CURLOPT_FILE,$fp);
curl_setopt($hander,CURLOPT_HEADER,0);
curl_setopt($hander,CURLOPT_FOLLOWLOCATION,1);
//curl_setopt($hander,CURLOPT_RETURNTRANSFER, false);//Return data in the form of data stream, when it is false, it is displayed directly
curl_setopt($hander,CURLOPT_TIMEOUT,60);
/*$options = array(
CURLOPT_URL=> 'http://jb51.net/content/uploadfile/201106/thum-f3ccdd27d2000e3f9255a7e3e2c4880020110622095243.jpg',
CURLOPT_FILE => $fp,
CURLOPT_HEADER => 0,
CURLOPT_FOLLOWLOCATION => 1,
CURLOPT_TIMEOUT => 60
);
curl_setopt_array($hander, $options);
*/
curl_exec($hander);
curl_close($hander);
fclose($fp);
Return true;
}
