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;     
    }     
?>
