PHP Curl Encapsulation Class Usage example

We need to open the PHP Curl module before using the function (Libeay32.dll, Ssleay32.dll, Php5ts.dll, Php_curl.dll)

To open the PHP Curl function library

1). remove Windows/php.ini file; Extension=php_curl.dll Front; /* Use echo phpinfo () to view the path of the php.ini * *

2). Copy the Php5/libeay32.dll,ssleay32.dll to the system directory windows/

3). Restart Apache

PHP Curl

The code is as follows

Copy Code

<?php Include_once (' curl.class.php '); $aa =new Curl ("); $curlOptions = Array ( Curlopt_url => "http://ww.ww.ww/addTicket.jsp",//Access URL Curlopt_returntransfer => True,//Get result returned as 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 Return header information Curlopt_ssl_verifypeer => false,//support for SSL encryption Curlopt_post => True,//send with POST parameter Curlopt_postfields => ' ids=897&submit=%e6%8a%95%e7%a5%a8 ',//requested post parameter string Curlopt_timeout => $aa->timeout//wait for response time ); echo $aa->getresponsetext ($curlOptions); Cul processing class <?php Class Curl { Public $cookieFile; Public $timeout = 160; Public Function __construct ($dir) { $this->cookiefile = $this->gettemporarycookiefilename ($dir); } /** * Set the curl parameter and send the request to get the response content * @access Private * @param $curlOptions Array Curl set parameter arrays * @return String|false Access succeeds, returns the obtained information as a string; */ Public Function GetResponseText ($curlOptions) { /* Set Curlopt_returntransfer to True * * if (!isset ($curlOptions [curlopt_returntransfer]) | | $curlOptions [Curlopt_returntransfer] = = False) { $curlOptions [Curlopt_returntransfer] = true; } /* Initialize Curl Module * * $curl = Curl_init (); /* Set CURL Option * * Curl_setopt_array ($curl, $curlOptions); * * Send request and get response information * * $responseText = '; try { $responseText = curl_exec ($curl); if (($errno = Curl_errno ($curl))!= Curlm_ok) { $errmsg = Curl_error ($curl); throw new Exception ($errmsg, $errno); } catch (Exception $e) { Exceptiondisposefunction ($e); Print_r ($e); $responseText = false; } /* Close Curl Module * * Curl_close ($curl); /* Return result * * return $responseText; } /** * Converts a Unicode string (u0000) to a utf-8 string, a tool function * @access Private * @static * @param $string string Unicode string * @return String Utf-8 strings */ Public Function UnicodeToUtf8 ($string) { $string = Str_replace (' u ', ', ', Strtolower ($string)); $length = strlen ($string)/4; $stringResult = '; for ($i = 0; $i < $length; $i + +) { $charUnicodeHex = substr ($string, $i * 4, 4); $unicodeCode = Hexdec ($charUnicodeHex); $utf 8Code = '; if ($unicodeCode < 128) { $utf 8Code = Chr ($unicodeCode); else if ($unicodeCode < 2048) { $utf 8Code. = Chr (($unicodeCode-($unicodeCode% 64))/64); $utf 8Code. = chr (128 + ($unicodeCode% 64)); } else { $utf 8Code. = Chr (224 + ($unicodeCode-($unicodeCode% 4096))/4096); $utf 8Code. = chr (128 + (($unicodeCode% 4096)-($unicodeCode% 64))/64); $utf 8Code. = chr (128 + ($unicodeCode% 64)); } $stringResult. = $utf 8Code; } return $stringResult; } Private Function gettemporarycookiefilename ($dir = '.
