以前使用curl的多線程並不是真正的多線程,只是一種模擬的多線程,現在使用pthreads來實現真正意義上的多線程。

安裝方式:
windows下:
解壓得到pthreadVC2.dll和php_pthreads.dll文件,把vc2文件放到php.exe同級目錄,把php_pthreads.dll放到擴展目錄下。
修改php.ini文件 添加extension=php_pthreads.dll
修改Apache配置文件httpd.conf 添加LoadFile "yourpath/php/pthreadVC2.dll"
mac、unix、linux下:

具體的用法也可以參考宴哥的博客http://blog.s135.com/pthreads/
結合以前的get_html也可以這樣來實現類
1 class threads extends Thread
2 {
3 public $url = '';
4 public $options = array();
5 public $data;
6
7 public function __construct($url, $options = array()){
8 $this->url = $url;
9 $this->options = $options;
10 }
11
12 public function run(){
13 if(!empty($this->url)){
14 $this->data = $this->get_html($this->url, $this->options);
15 }
16 }
17
18 public function get_html($url,$options = array()){
19 if(empty($options)){
20 $options[CURLOPT_RETURNTRANSFER] = true;
21 $options[CURLOPT_TIMEOUT] = 5;
22 }
23 $ch = curl_init($url);
24 curl_setopt_array($ch,$options);
25 $html = curl_exec($ch);
26 curl_close($ch);
27 if($html === false){
28 return false;
29 }
30 return $html;
31 }
32 }
