模拟PHP-CURL向远程服务器上传文件

目录结构图：

【本例把upload文件夹当做远程服务器下的文件夹】

运行127.0.0.1/test.php

test.php

$file_url = './img/5.jpg';

$url = 'http://127.0.0.1/upload/upload.php?dirname=news';

$pathinfo = pathinfo($file_url);

$filename = $pathinfo['basename'];

$path = $file_url;

$type = $pathinfo['extension'];

$data = upload_file($url, $filename, $path, $type);

var_dump($data) ;

 

 

/**

* @param string $url

* @param string $filename

* @param string $path

* @param string $type

* @return string

*/

function upload_file($url,$filename,$path,$type){

//php 5.5以上的用法

if (class_exists('\CURLFile')) {

$data = array('file' => new \CURLFile(realpath($path),$type,$filename));

} else {

$data = array(

'file'=>'@'.realpath($path).";type=".$type.";filename=".$filename

);

}

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_POST, true );

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl_setopt($ch, CURLOPT_HEADER, false);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$return_data = curl_exec($ch);

curl_close($ch);

return $return_data;

}
