PHP Curl Encapsulation Class Usage Example _php skill

The examples in this article illustrate the usages of two PHP Curl encapsulation classes, which allow us to use PHP curl related functions very conveniently. Share to everyone for your reference. Specifically 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 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

The code is as follows:

Copy Code code as follows:

<?php
Include_once (' curl.class.php ');
$aa =new Curl (");
$curlOptions = Array (
Curlopt_url => "http://www.xx.com/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:

Copy Code code as follows:

<?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 = '. ') {
Return (Str_replace ("", '/", Tempnam ($dir, ' tmp '));
}
}
