方式1：sockets

$a = "/content/uploadfile/06/thum-f3ccdd27d2000e3f9255a7e3e2c488000622095243.jpg";

$local = 'socket1.gif';

$aa = getImg($a,$local);

*@ 完整的图片地址

*@ 要存储的文件名

function getImg( $url = "", $filename = "" ) {

if(is_dir(basename($filename))) {

echo "The Dir was not exits";

Return false;

}

//去除URL连接上面可能的引号

$url = preg_replace( '/(?:^[\'"]+|[\'"\/]+$)/', '', $url );

if (!extension_loaded('sockets')) return false;

//获取url各相关信息

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;

}

//图片的相对地址

$msg = 'GET ' . $matches[3] . " HTTP/1.1\r\n";

//主机名称

$msg .= 'Host: ' . $matches[1] . "\r\n";

$msg .= 'Connection: Close' . "\r\n\r\n";

socket_write( $sock, $msg );

$bin = '';

while ( $tmp = socket_read( $sock, 10 ) ) {

$bin .= $tmp;

$tmp = '';

}

$bin = explode("\r\n\r\n", $bin);

$img = $bin[1];

$h = fopen( $filename, 'wb' );

$res = fwrite( $h, $img ) === false ? false : true;

@socket_close( $sock );

Return $res;

}

方式2：curl
