使用CURL抓資料的PHP函數，可以給予URL資料，然後得到回傳的結果

curl_example.php

<?php
$xml_file = file_get_contents(SITE_PATH . 'cms/data.php');

//CURL

function url_get_contents ($Url) {
    if (!function_exists('curl_init')){ 
        die('CURL is not installed!');
    }
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $Url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}
