We have introduced to you the implementation method of PHP multi-threading and asynchronous calls before. We all know that multi-threading implemented through WEB servers can only imitate some effects of multi-threading, and is not multi-threading in the true sense. But no matter Anyway, it can still meet some of our needs, so today we will implement the PHP multi-threaded class!

php multi-threaded class:

/** 
* @title: PHP多线程类(Thread) 
* @version: 1.0 
* 
* PHP多线程应用示例： 
* require_once &#39;thread.class.php&#39;; 
* $thread = new thread(); 
* $thread->addthread(&#39;action_log&#39;,&#39;a&#39;); 
* $thread->addthread(&#39;action_log&#39;,&#39;b&#39;); 
* $thread->addthread(&#39;action_log&#39;,&#39;c&#39;); 
* $thread->runthread(); 
* 
* function action_log($info) { 
* $log = &#39;log/&#39; . microtime() . &#39;.log&#39;; 
* $txt = $info . "rnrn" . &#39;Set in &#39; . Date(&#39;h:i:s&#39;, time()) . (double)microtime() . "rn"; 
* $fp = fopen($log, &#39;w&#39;); 
* fwrite($fp, $txt); 
* fclose($fp); 
* }

class thread { 
var $hooks = array(); 
var $args = array(); 
function thread() { 
} 
function addthread($func) 
{ 
$args = array_slice(func_get_args(), 1); 
$this->hooks[] = $func; 
$this->args[] = $args; 
return true; 
} 
function runthread() 
{ 
if(isset($_GET[&#39;flag&#39;])) 
{ 
$flag = intval($_GET[&#39;flag&#39;]); 
} 
if($flag || $flag === 0) 
{ 
call_user_func_array($this->hooks[$flag], $this->args[$flag]); 
} 
else 
{ 
for($i = 0, $size = count($this->hooks); $i < $size; $i++) 
{ 
$fp=fsockopen($_SERVER[&#39;HTTP_HOST&#39;],$_SERVER[&#39;SERVER_PORT&#39;]); 
if($fp) 
{ 
$out = "GET {$_SERVER[&#39;PHP_SELF&#39;]}?flag=$i HTTP/1.1rn"; 
$out .= "Host: {$_SERVER[&#39;HTTP_HOST&#39;]}rn"; 
$out .= "Connection: Closernrn"; 
fputs($fp,$out); 
fclose($fp); 
} 
} 
} 
}

Usage method, the code is as follows:

$thread = new thread(); 
$thread->addthread(&#39;func1&#39;,&#39;info1&#39;); 
$thread->addthread(&#39;func2&#39;,&#39;info2&#39;); 
$thread->addthread(&#39;func3&#39;,&#39;info3&#39;); 
$thread->runthread();

Instructions:

addthread() is to add Thread function, the first parameter is the function name, and the subsequent parameters (optional) are the parameters passed to the specified function .

runthread() is the function of the execution thread.

Summary:

This article shares with you a PHP multi-threaded class. You don’t need to write so much code in the future. You will need it next time. You can call it directly at that time. I hope it can be helpful to you!
