php后台传值到另一个php

比如

if ($h=1)｛
$a = 3;
$b = 8;
后台执行http://www.1.com/88.php?a=3&b=8代码应当怎么写

function geturl($url){
        $headerArray =array("Content-type:application/json;","Accept:application/json");
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch,CURLOPT_HTTPHEADER,$headerArray);
        $output = curl_exec($ch);
        curl_close($ch);
        $output = json_decode($output,true);
        return $output;
}
geturl("http://www.1.com/88.php?a=3&b=8") // 调用方法执行
