php發送post請求函數分享

 這篇文章主要介紹了一個php發送post請求的函數，開發中經常會用到，需要的朋友可以參考下

 代碼如下:function do_post_request($url, $data, $optional_headers = null){ $params = array('http' => array('method' => 'POST','content' => $data )); if ($optional_headers !== null) {$params['http']['header'] = $optional_headers; } $ctx = stream_context_create($params); $fp = @fopen($url, 'rb', false, $ctx); if (!$fp) {throw new Exception("Problem with $url, $php_errormsg"); } $response = @stream_get_contents($fp); if ($response === false) {throw new Exception("Problem reading data from $url, $php_errormsg"); } return $response;}   用法如下： 代碼如下://json字串$data = "{...}";//轉換成數組$data=json_decode($data,true);$postdata = http_build_query($data);do_post_request("http://localhost",$postdata);
