以前使用curl的多线程并不是真正的多线程,只是一种模拟的多线程,现在使用pthreads来实现真正意义上的多线程。

windows下:

安装方式:
windows下:
解压得到pthreadVC2.dll和php_pthreads.dll文件,把vc2文件放到php.exe同级目录,把php_pthreads.dll放到扩展目录下。
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"

结合以前的get_html也可以这样来实现类
class threads extends Thread
{
public $url = '';
public $options = array();
public $data; public function __construct($url, $options = array()){
$this->url = $url;
$this->options = $options;
} public function run(){
if(!empty($this->url)){
$this->data = $this->get_html($this->url, $this->options);
}
} public function get_html($url,$options = array()){
if(empty($options)){
$options[CURLOPT_RETURNTRANSFER] = true;
$options[CURLOPT_TIMEOUT] = 5;
}
$ch = curl_init($url);
curl_setopt_array($ch,$options);
$html = curl_exec($ch);
curl_close($ch);
if($html === false){
return false;
}
return $html;
}
}
