php curl encapsulation class usage example, phpcurl encapsulation example

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 enable php curl function library

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

The code is as follows:

Copy code 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, //Get the result and return it as a string
CURLOPT_REFERER => "ww.ww.ww/zw2",
CURLOPT_HTTPHEADER => array('X-FORWARDED-FOR:139.197.14.19', 'CLIENT-IP:127.0.0.1','Proxy-Client-IP:139.197.14.19','WL-Proxy-Client-IP:139.197 .14.19' ),
CURLOPT_HEADER => 1, //Get the return header information
//CURLOPT_SSL_VERIFYPEER => false, //Support SSL encryption
CURLOPT_POST => true, //Send with POST parameters
CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //Requested POST parameter string
CURLOPT_TIMEOUT => $aa->timeout //Time to wait for response
);
echo $aa->getResponseText($curlOptions);

cul processing class:

    }

}
?>

用法

GET用法：

复制代码代码如下:

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

POST用法：

复制代码代码如下:

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

php curl 封装成函数问题

The reason is that the variable name is written incorrectly. Variable name ② is equal to variable name ③ but not equal to variable name ①. Remember to adopt it!
$output ①= curl_exec($ch); //Return results;
curl_close($ch); //Close communication;
if($output==''){
$outptu② = 3;
}
$dataapi = $outptu③;
return $dataapi;
}
