Php curl encapsulation class usage instance. Php curl encapsulation class usage before using the function, we need to open the phpcurl module (libeay32.dll, ssleay32.dll, php5ts. dll, php_curl.dll) to enable the phpcurl function library step 1 ). examples of curl encapsulation class usage in php
Before using the function, we need to open the php curl module (libeay32.dll, ssleay32.dll, php5ts. dll, php_curl.dll)
To enable the php curl function library
1) remove the file in windows/php. ini; prefix extension = php_curl.dll;/* use echo phpinfo () to view the php. ini path */
2) copy php5/libeay32.dll and ssleay32.dll to the system directory windows/
3) restart apache
The code is as follows:
The code is as follows:
Include_once ('curl. class. php ');
$ Aa = new Curl ('');
$ CurlOptions = array (
CURLOPT_URL => "http://www.xx.com/addTicket.jsp", // access URL
CURLOPT_RETURNTRANSFER => true, // returns the result as a string.
CURLOPT_REFERER => "ww. ww. ww/zw2 ",

CURLOPT_HEADER => 1, // Get the returned header information
// CURLOPT_SSL_VERIFYPEER => false, // supports SSL encryption
CURLOPT_POST => true, // The POST parameter is included in the sending process.
CURLOPT_POSTFIELDS => 'IDS = 897 & Submit = % E6 % 8A % 95% E7 % A5 % A8 ', // the request's POST parameter string
