本文實例講述了php實現的Curl封裝類Curl.class.php用法。分享給大家供大家參考。具體如下:
- <?php
- //curl類
- 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, $url);
- }else{
- return false;
- }
- //是否顯示頭部信息
- curl_setopt($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);//設置curl超時秒數
- 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');
希望本文所述對大家的php程序設計有所幫助。
