使用函數(shù)之前我們要需要把php curl模塊打開(libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

開啟php curl函數(shù)庫的步驟

1).去掉windows/php.ini 文件里;extension=php_curl.dll前面的; /*用 echo phpinfo();查看php.ini的路徑*/

2).把php5/libeay32.dll，ssleay32.dll復制到系統(tǒng)目錄windows/下

3).重啟apache

代碼如下：

代碼如下:

<?php

include_once('curl.class.php');

$aa =new Curl('');

$curlOptions = array(

CURLOPT_URL => "", //訪問URL

CURLOPT_RETURNTRANSFER => true, //獲取結(jié)果作為字符串返回

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, //獲取返回頭信息

//CURLOPT_SSL_VERIFYPEER => false, //支持SSL加密

CURLOPT_POST => true, //發(fā)送時帶有POST參數(shù)

CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //請求的POST參數(shù)字符串

CURLOPT_TIMEOUT => $aa->timeout //等待響應的時間

);

echo $aa->getResponseText($curlOptions);

cul處理類：

代碼如下:

<?php

class Curl

{

public $cookieFile;

public $timeout = 160;

Public function __construct($dir){

$this->cookieFile = $this->getTemporaryCookieFileName($dir);

}

/**

* 設置CURL參數(shù)并發(fā)送請求，獲取響應內(nèi)容

* @access private

* @param $curlOptions array curl設置參數(shù)數(shù)組

* @return string|false 訪問成功，按字符串形式返回獲取的信息；否則返回false

*/

public function getResponseText($curlOptions) {

/* 設置CURLOPT_RETURNTRANSFER為true */

if(!isset($curlOptions[CURLOPT_RETURNTRANSFER]) || $curlOptions[CURLOPT_RETURNTRANSFER] == false) {

$curlOptions[CURLOPT_RETURNTRANSFER] = true;

}

/* 初始化curl模塊 */

$curl = curl_init();

/* 設置curl選項 */

curl_setopt_array($curl, $curlOptions);

/* 發(fā)送請求并獲取響應信息 */

$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;

}

/* 關閉curl模塊 */

curl_close($curl);

/* 返回結(jié)果 */

return $responseText;

}

/**

* 將Unicode字符串(u0000)轉(zhuǎn)化為utf-8字符串，工具函數(shù)

* @access private

* @static

* @param $string string Unicode字符串

* @return string utf-8字符串

*/

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')));

}

}

代碼如下:

例子2

代碼如下:

<?php

//curl類

class Curl

{

function Curl(){

return true;

}

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;

}

//是否顯示頭部信息

curl_setopt($ch, CURLOPT_HEADER, false);

//

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

if($username != ''){

curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);

}

$method = strtolower($method);

if('post' == $method){

curl_setopt($ch, CURLOPT_POST, true);

if(is_array($fields)){

$sets = array();

foreach ($fields AS $key => $val){

$sets[] = $key . '=' . urlencode($val);

}

$fields = implode('&',$sets);

}

curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

}else if('put' == $method){

curl_setopt($ch, CURLOPT_PUT, true);

}

//curl_setopt($ch, CURLOPT_PROGRESS, true);

//curl_setopt($ch, CURLOPT_VERBOSE, true);

//curl_setopt($ch, CURLOPT_MUTE, false);

curl_setopt($ch, CURLOPT_TIMEOUT, 10);//設置curl超時秒數(shù)

if(strlen($userAgent)){

curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);

}

if(is_array($httpHeaders)){

curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);

}

$ret = curl_exec($ch);

if(curl_errno($ch)){

curl_close($ch);

return array(curl_error($ch), curl_errno($ch));

}else{

curl_close($ch);

if(!is_string($ret) || !strlen($ret)){

return false;

}

return $ret;

}

}

function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){

$ret = Curl::execute('POST', $url, $fields, $userAgent, $httpHeaders, $username, $password);

if(false === $ret){

return false;

}

if(is_array($ret)){

return false;

}

return $ret;

}

function get($url, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){

$ret = Curl::execute('GET', $url, '', $userAgent, $httpHeaders, $username, $password);

if(false === $ret){

return false;

}

if(is_array($ret)){

return false;

}

return $ret;

}

function create(){

$ch = null;

if(!function_exists('curl_init')){

return false;

}

$ch = curl_init();

if(!is_resource($ch)){

return false;

}

return $ch;

}

}

?>

用法

GET用法：

代碼如下:

$curl = new Curl();

$curl->get('http://www.jb51.net/');

POST用法：

代碼如下:

$curl = new Curl();

$curl->get('http://www.jb51.net/', 'p=1&time=0′);
