PHP利用curl发送HTTP请求的实例代码

<?php
function geturl($url){
    $headerArray =array("Content-type:application/json;","Aept:application/json");

    curl_set($ch, CURLOPT_URL, $url);

    curl_set($ch,CURLOPT_HTTPHEADER,$headerArray);
    $output = curl_exec($ch);
    curl_close($ch);
    $output = json_decode($output,true);
    return $output;
}


function posturl($url,$data){

    curl_close($curl);
    return json_decode($output，true);
}
