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

<code><span><?php </span><span><span>class</span><span>test</span><span>extends</span><span>Thread</span> {</span><span>public</span><span><span>function</span><span>__construct</span><span>(<span>$fun</span>)</span>
 {</span><span>$this</span>->fun=<span>$fun</span>;
 }

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

  <span>private</span><span><span>function</span><span>test1</span><span>()</span>
  {</span><span>echo</span><span>1</span>;
    <span>echo</span><span>"<br>"</span>;

  }

  <span>private</span><span><span>function</span><span>test2</span><span>()</span>
  {</span>
    sleep(<span>3</span>);
    <span>echo</span><span>2</span>;
    <span>echo</span><span>"<br>"</span>;
  }

  <span>private</span><span><span>function</span><span>test3</span><span>()</span>
  {</span><span>echo</span><span>3</span>;
    <span>echo</span><span>"<br>"</span>;
  }

}

<span>$arr</span>=<span>array</span>(<span>'test1'</span>,<span>'test2'</span>,<span>'test3'</span>);

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

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



</span></code>

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
http://php.net/manual/zh/class.thread.php

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

以上就介绍了php thread扩展的使用，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
