PHP's Curl wrapper class usage Example

This example describes the usage examples of two PHP Curl wrapper classes, which make it very convenient for us to use the PHP curl correlation function. Share to everyone for your reference. Specific as follows:

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 Library

1). Remove the Windows/php.ini file; Extension=php_curl.dll Front; /* with Echo phpinfo (); View PHP.ini's Path */
2). Copy the Php5/libeay32.dll,ssleay32.dll to the system directory windows/
3). Restart Apache

The code is as follows:

<?phpinclude_once (' curl.class.php '); $aa =new Curl ('); $curlOptions = Array (curlopt_url = "http://www.xx.com/addTicket.jsp",//Access URL Curlopt_returntransfer = true,// Gets the result as a string return 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 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//Time to wait for response); echo $aa->getresponsetext ($curlOptions);

Cul processing class:

<?phpclass curl{public $cookieFile;p ublic $timeout = 160; Public function __construct ($dir) {$this->cookiefile = $this->gettemporarycookiefilename ($dir);} /*** set the curl parameter and send the request, get the response content * @access private* @param $curlOptions Array Curl Set the parameter arrays * @return String|false access succeeded, Returns the obtained information as a string, otherwise returns False*/public function GetResponseText ($curlOptions) {/* set Curlopt_returntransfer to True */if (! Isset ($curlOptions [curlopt_returntransfer]) | | $curlOptions [Curlopt_returntransfer] = = False) {$curlOptions [curlopt_returntransfer] = true;} /* Initialize the 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); $responseText = false;} /* Turn off the Curl Module */curl_close ($curl);/* Return the result */return $responseText;} /*** converts a Unicode string (u0000) to a utf-8 string, the tool function * @access Private* @static * @param $string string Unicode String * @return string Utf-8 string */public function UnicodeToUtf8 ($string) {$stri ng = Str_replace (' u ', ' ', Strtolower ($string)); $length = strlen ($string)/4; $stringResult = "; for ($i = 0; $i < $lengt H  $i + +) {$charUnicodeHex = substr ($string, $i * 4, 4), $unicodeCode = Hexdec ($charUnicodeHex); $utf 8Code = "; if ($unicodeCode <) {$utf 8Code = Chr ($unicodeCode),} else if ($unicodeCode < 2048) {$utf 8Code. = Chr (192 + ($unicodeCode-($uni Codecode)), $utf 8Code. = Chr (+ ($unicodeCode% 64));} else {$utf 8Code. = Chr (224 + ($unicodeCode-($unicodeCode% 4096)/4096)), $utf 8Code. = Chr (+ (($unicodeCode% 409 6)-($unicodeCode)), $utf 8Code. = Chr (+ ($unicodeCode% 64));} $stringResult. = $utf 8Code;} return $stringResult;} Private Function gettemporarycookiefilename ($dir = '. ') {return (Str_replace ("", '/', Tempnam ($dir, ' tmp '))}}

Example 2

<?php//curl class curl{function Curl () {return true;        The 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, $url);        }else{return false;        }//whether to display header information curl_setopt ($ch, Curlopt_header, false);        curl_setopt ($ch, Curlopt_returntransfer, true); if ($username! = ") {curl_setopt ($ch, Curlopt_userpwd, $username.

Usage

Get usage:

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

Post usage:

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

I hope this article is helpful to everyone's PHP programming.
