复制代码 代码如下:
$a = "http://jb51.NET/content/uploadfile/201106/thum-f3ccdd27d2000e3f9255a7e3e2c4880020110622095243.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
复制代码 代码如下:
<?php
$url = "http://jb51.NET/content/uploadfile/201106/thum-f3ccdd27d2000e3f9255a7e3e2c4880020110622095243.jpg";
$filename = 'curl.gif';
//http://jb51.NET
getImg($url, $filename);
/*
*@通过curl方式获取制定的图片到本地
*@ 完整的图片地址
*@ 要存储的文件名
*/
function getImg($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 );
$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($hander,CURLOPT_RETURNTRANSFER,false);//以数据流的方式返回数据,当为false是直接显示出来
curl_setopt($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;
}
