Case study of implementing PHP multi-threading class
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 'thread.class.php';
* $thread = new thread();
* $thread->addthread('action_log','a');
* $thread->addthread('action_log','b');
* $thread->addthread('action_log','c');
* $thread->runthread();
*
* function action_log($info) {
* $log = 'log/' . microtime() . '.log';
* $txt = $info . "rnrn" . 'Set in ' . Date('h:i:s', time()) . (double)microtime() . "rn";
* $fp = fopen($log, 'w');
* 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['flag']))
{
$flag = intval($_GET['flag']);
}
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['HTTP_HOST'],$_SERVER['SERVER_PORT']);
if($fp)
{
$out = "GET {$_SERVER['PHP_SELF']}?flag=$i HTTP/1.1rn";
$out .= "Host: {$_SERVER['HTTP_HOST']}rn";
$out .= "Connection: Closernrn";
fputs($fp,$out);
fclose($fp);
}
}
}
}
}Usage method, the code is as follows:
$thread = new thread(); $thread->addthread('func1','info1'); $thread->addthread('func2','info2'); $thread->addthread('func3','info3'); $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!

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
