PHP curl encapsulation class usage example_PHP tutorial

Examples of using php curl encapsulation class

Before using the function, we need to open the php curl module (libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

Steps to open the php curl function library

　1). Remove the ;extension=php_curl.dll in the windows/php.ini file; /*Use echo phpinfo(); to view the path of php.ini*/

　2). Copy php5/libeay32.dll and ssleay32.dll to the system directory windows/

　3). Restart apache

php curl

The code is as follows

include_once('curl.class.php'); $aa =new Curl(''); $curlOptions = array( CURLOPT_URL => "http://ww.ww.ww/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 class Curl { public $cookieFile; public $timeout = 160; Public function __construct($dir){ $this->cookieFile = $this->getTemporaryCookieFileName($dir); } /** * Set CURL parameters and send a request to get the response content * @access private * @param $curlOptions array curl setting parameter array * @return string|false If the access is successful, the obtained information will be returned in string form; otherwise, false */ public function getResponseText($curlOptions) { /* Set CURLOPT_RETURNTRANSFER to true */ if(!isset($curlOptions[CURLOPT_RETURNTRANSFER]) || $curlOptions[CURLOPT_RETURNTRANSFER] == false) { $curlOptions[CURLOPT_RETURNTRANSFER] = true; } /* Initialize curl module */ $curl = curl_init(); /* Set curl options */ curl_setopt_array($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 results */ return $responseText; } /** * Convert Unicode string (u0000) to utf-8 string, tool function * @access private * @static * @param $string string Unicode string * @return string utf-8 string */ public function unicodeToUtf8($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); $utf8Code = ''; if($unicodeCode < 128) { $utf8Code = chr($unicodeCode); } else if($unicodeCode < 2048) { $utf8Code .= chr(192 + (($unicodeCode - ($unicodeCode % 64)) / 64)); $utf8Code .= chr(128 + ($unicodeCode % 64)); } else { $utf8Code .= chr(224 + (($unicodeCode - ($unicodeCode % 4096)) / 4096)); $utf8Code .= chr(128 + ((($unicodeCode % 4096) - ($unicodeCode % 64)) / 64)); $utf8Code .= chr(128 + ($unicodeCode % 64)); } $stringResult .= $utf8Code; } return $stringResult; } private function getTemporaryCookieFileName($dir='.') { return (str_replace("", '/', tempnam($dir, 'tmp'))); } }
