php实现多线程_PHP

act fclose if accomplish

PHP本身是不支持多线程的, 但apache是支持多线程的
我知道的有2种:
1,同页面iframe,这个比较不好,不能很好实现参数传递
2,例子

go.php

[CODE][function runThread()
{
$fp = fsockopen('localhost', 80, $errno, $errmsg);

fputs($fp, "GET /go.php?act=b\r\n\r\n");

fclose($fp);
}

function a()
{
$fp = fopen('1.txt', 'w');
fputs($fp, 'Set in ' . Date('h:i:s', time()) . (double)microtime() . "\r\n");

fclose($fp);
}

function b()
{
$fp = fopen('2.txt', 'w');
fputs($fp, 'Set in ' . Date('h:i:s', time()) . (double)microtime() . "\r\n");

fclose($fp);
}

if(!isset($_GET['act'])) $_GET['act'] = 'a';

if($_GET['act'] == 'a')
{
runThread();
a();
}
else if($_GET['act'] == 'b') b();
?>/CODE]

速度够快的话你可以发现 1.txt 和 2.txt 有些时间一样的
