php实现的Curl封装类Curl.class.php用法实例分析_php技巧

<?php //curl类 class Curl { function Curl(){ return true; } function execute($method, $url, $fields='', $userAgent='', $httpHeaders='', $username='', $password=''){ $ch = Curl::create(); if(false === $ch){ return false; } if(is_string($url) && strlen($url)){ $ret = curl_setopt($ch, CURLOPT_URL, $url); }else{ return false; } //是否显示头部信息 curl_setopt($ch, CURLOPT_HEADER, false); // curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); if($username != ''){ curl_setopt($ch, CURLOPT_USERPWD, $username .

$curl = new Curl(); $curl->get('http://www.XXX.com/');

$curl = new Curl(); $curl->get('http://www.XXX.com/', 'p=1&time=0');
