PHP 线程安全，多线程

3.添加扩展 php.ini添加 : extension=pthreads.so; 如果你是之前安装过php，那么， /usr/local/php-zts/bin/php -i|grep php.ini 这个语句帮你找到php.ini位置。 找出php.ini的位置，修改它把ext=pthreads.so加入进入进去，因为我原来就有php，现在新装的php

3.添加扩展

php.ini添加 : extension=pthreads.so;

如果你是之前安装过php，那么，/usr/local/php-zts/bin/php -i|grep "php.ini" 这个语句帮你找到php.ini位置。

找出php.ini的位置，修改它把ext=pthreads.so加入进入进去，因为我原来就有php，现在新装的php.ini文件不存在我就考了一个过去……

4.查看扩展是否安装成功

/usr/local/php5.5.12-zts/bin/php -i | grep -i pthreads

测试代码：

/*

* Sharing symbols 101

* @NOTE Thread::fetch was never included in a release and was superceeded by object handlers

* pthreads allows read access to thread data from any context

pthreads allows write access to thread data from any context

carry on reading ...

work in progress ...

*/

classTestObject {

public$val;

}

classFetching extendsThread {

publicfunction run(){

/*

* of course ...

*/

$this->sym = 10245;

$this->arr = array(

"1","2","3"

);

echo'6'.chr(10);

/*

* objects do work, no preparation needed ...

* read/write objects isn't finalized ..

* so do the dance to make it work ...

*/

$obj= newTestObject();

$obj->val = "testval";

$this->obj = $obj;

echo'7'.chr(10);

/*

* will always work

*/

$this->objs = serialize($this->obj);

echo'8'.chr(10);

/*

* nooooooo

*/

$this->res = fopen("php://stdout","w");

echo'9'.chr(10);

/*

* tell the waiting process we have created symbols and fetch will succeed

*/

$this->synchronized(function(){

$this->notify();

});

echo'10'.chr(10);

/* wait for the process to be finished with the stream */

$this->synchronized(function(){

$this->wait();

});

echo'11'.chr(10);

}

}

echo'0'.chr(10);

$thread= newFetching();

echo'1'.chr(10);

$thread->start();

//sleep(1); 加了这个就不能正常工作，真奇怪

echo'2'.chr(10);

$thread->synchronized(function($me){

echo'3'.chr(10);

$me->wait();

echo'4'.chr(10);

},$thread);

echo'5'.chr(10);

/*

* we just got notified that there are symbols waiting

*/

foreach(array("sym","arr","obj","objs","res")as$symbol){

printf("\$thread->%s: ",$symbol);

$fetched= $thread->$symbol;

if($fetched) {

switch($symbol){

/*

* manual unserialize

*/

case"objs":

var_dump(unserialize($fetched));

break;

default: var_dump($fetched);

}

}

printf("\n");

}

/* notify the thread so it can destroy resource */

$thread->synchronized(function($me){

$me->notify();

},$thread);

?>

在命令框输入：/usr/local/php-zts/bin/php Fetch.php

直接在网页没有输出，需要调用PHP脚本运行。
