php实现的Curl封装类Curl.class.php用法实例分析
本文实例讲述了php实现的Curl封装类Curl.class.php用法。分享给大家供大家参考。具体如下：
<?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 . ':' . $password);
}
$method = strtolower($method);
if('post' == $method){
curl_setopt($ch, CURLOPT_POST, true);
if(is_array($fields)){
$sets = array();
foreach ($fields AS $key => $val){
$sets[] = $key . '=' . urlencode($val);
}
$fields = implode('&',$sets);
}
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
}else if('put' == $method){
curl_setopt($ch, CURLOPT_PUT, true);
}
//curl_setopt($ch, CURLOPT_PROGRESS, true);
//curl_setopt($ch, CURLOPT_VERBOSE, true);
//curl_setopt($ch, CURLOPT_MUTE, false);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);//设置curl超时秒数
if(strlen($userAgent)){
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
}
if(is_array($httpHeaders)){
curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);
}
$ret = curl_exec($ch);
if(curl_errno($ch)){
curl_close($ch);
return array(curl_error($ch), curl_errno($ch));
}else{
curl_close($ch);
if(!is_string($ret) || !strlen($ret)){
return false;
}
return $ret;
}
}
function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
$ret = Curl::execute('POST', $url, $fields, $userAgent, $httpHeaders, $username, $password);
if(false === $ret){
return false;
}
if(is_array($ret)){
return false;
}
return $ret;
}
function get($url, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
$ret = Curl::execute('GET', $url, '', $userAgent, $httpHeaders, $username, $password);
if(false === $ret){
return false;
}
if(is_array($ret)){
return false;
}
return $ret;
}
function create(){
$ch = null;
if(!function_exists('curl_init')){
return false;
}
$ch = curl_init();
if(!is_resource($ch)){
return false;
}
return $ch;
}
}
?>
GET用法：
$curl = new Curl();
$curl->get('http://www.XXX.com/');
POST用法：
$curl = new Curl();
$curl->get('http://www.XXX.com/', 'p=1&time=0');
希望本文所述对大家的php程序设计有所帮助。
