PHP从一台服务器将图片发送到另一台服务器并保存

由于我们的后台和前台是不同的php框架，而且后台和前台不在同一台服务器上，现在有一个问题，就是从后台上传图片要保存在前台的框架中。

我们后台用的是laravel框架

    public function laraveltest(Request $request) {
	$file = $request->file('file');
    	if($file -> isValid()){
	    	$clientName = $file -> getClientOriginalName();
	    	$tmpName = $file ->getFileName();
	    	$realPath = $file -> getRealPath();
	    	$entension = $file -> getClientOriginalExtension();
	    	$newName = md5($clientName).".".$entension;
	    	$url_path = 'upload/banner/';
	        $path = $file -> move($url_path,$newName);
	        $pathName = json_decode($path,TRUE);
	        $url1 = "http://47.101.54.26/test/testuploadpic";
	        $url2 = "http://47.101.54.27/test/testuploadpic";
	        $url3 = "http://47.101.54.28/test/testuploadpic";
	        $this->curl($path,$url1);
	        $this->curl($path,$url2);
	        $this->curl($path,$url3);
	        $returnPath = '/upload/banner/'.$newName;
	        return $this->json($returnPath);
    	}
    }

    public function curl($path,$url){
    	$curl = curl_init();
		if (class_exists('\CURLFile')) {
		  	curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);
			$data = array('file' => new \CURLFile(realpath($path)));//>=5.5
		}else{
		  	if (defined('CURLOPT_SAFE_UPLOAD')) {
		    	curl_setopt($curl, CURLOPT_SAFE_UPLOAD, false);
		  	}
		  	$data = array('file' => '@' . realpath($path));//<=5.5
		}
		
		curl_setopt($curl, CURLOPT_URL, $url);
		curl_setopt($curl, CURLOPT_POST, 1 );
		curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
		curl_setopt($curl, CURLOPT_USERAGENT,"TEST");
		$result = curl_exec($curl);
		$error = curl_error($curl);
    }

通过上面两个方法就可以将图片发送到另外一台服务器，我写了3台服务器是因为我想说明可以发送到无数台服务器

下面的代码是在另外一台服务器上接收到图片信息后保存图片

    public function testuploadpic(){
        $filename = $_FILES['file']['name'];
        $tmpname = $_FILES['file']['tmp_name'];
        $url = '/home/testuploadpic';
        if(move_uploaded_file($tmpname, $url.$filename))
        {
            echo json_encode('上传成功');
        }
    }

这样就可以保存下来了！！！
