php thread扩展的使用

安装教程请参考thread安装

直接上一段简单的代码

 
class test extends Thread {

 public function __construct($fun)
 {
    $this->fun=$fun;
 }

  public function run() {
    $param=$this->fun;
    $this->$param();
  }

  private function test1()
  {
    echo 1;
    echo "
";

  }

  private function test2()
  {
    sleep(3);
    echo 2;
    echo "
";
  }

  private function test3()
  {
    echo 3;
    echo "
";
  }

}

$arr=array('test1','test2','test3');

foreach ($arr as $fun)
{
    $th[]=new test($fun);
}

foreach ($th as $worker)
{
    $worker->start();
}

输出结果是
1
3
2

test 类继承thread类，需要实现run方法，start方法会自动开启一个线程来执行run方法里的程序，thread具体的方法请参考官方手册
