<?php     

    $url = 'http://127.0.0.1/test.php';//POST指向的链接     
    $data = array(     
        'access_token'=>'thekeyvalue'    
    );     

    $json_data = postData($url, $data);     
    $array = json_decode($json_data,true);     
    echo '<pre>';print_r($array);     

    function postData($url, $data)     
    {     
        $ch = curl_init();     
        $timeout = 300;      
        curl_setopt($ch, CURLOPT_URL, $url);    
        curl_setopt($ch, CURLOPT_REFERER, "https://www.jb51.net/");   //构造来路   
        curl_setopt($ch, CURLOPT_POST, true);     
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);     
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);     
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);     
        $handles = curl_exec($ch);     
        curl_close($ch);     
        return $handles;
