The examples in this article describe two usage examples of the php curl encapsulation class. These two functions allow us to use php curl related functions very conveniently. Share it with everyone for your reference. The details are as follows:

Before using the function, we need to open the php curl module (libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

Steps to open the php curl function library

1). Remove windows/ In the php.ini file; in front of extension=php_curl.dll; /*Use echo phpinfo(); to view the path of php.ini*/
2). Copy php5/libeay32.dll and ssleay32.dll to the system directory windows/ Next
3). Restart apache

The code is as follows:

<?php
include_once(&#39;curl.class.php&#39;);
$aa =new Curl(&#39;&#39;);
 $curlOptions = array(
 CURLOPT_URL => "http://www.xx.com/addTicket.jsp", //訪問URL
 CURLOPT_RETURNTRANSFER => true, //獲取結(jié)果作為字符串返回
 CURLOPT_REFERER => "ww.ww.ww/zw2",
 CURLOPT_HTTPHEADER => array(&#39;X-FORWARDED-FOR:139.197.14.19&#39;, &#39;CLIENT-IP:127.0.0.1&#39;,&#39;Proxy-Client-IP:139.197.14.19&#39;,&#39;WL-Proxy-Client-IP:139.197.14.19&#39; ),
 CURLOPT_HEADER => 1, //獲取返回頭信息
 //CURLOPT_SSL_VERIFYPEER => false, //支持SSL加密
 CURLOPT_POST => true, //發(fā)送時(shí)帶有POST參數(shù)
 CURLOPT_POSTFIELDS => &#39;ids=897&Submit=%E6%8A%95%E7%A5%A8&#39;, //請(qǐng)求的POST參數(shù)字符串
 CURLOPT_TIMEOUT => $aa->timeout //等待響應(yīng)的時(shí)間
 );
 echo $aa->getResponseText($curlOptions);

cul processing class:

<?php

$this->cookieFile = $this->getTemporaryCookieFileName($dir);

usage

GET usage:

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

POST usage:

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

I hope this article The above will be helpful for everyone's PHP programming.
