PHP USES the code of POST data to API interface in CURL mode

In fact, it is also relatively simple, on the code:

<?php      

    $url = 'http://127.0.0.1/test.php';//POST Links to       
    $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.ofstack.com/");   // Tectonic background     
        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;      
    }      
?>
