php安装threads多线程扩展
php5.3或以上,且为线程安全版本。apache和php使用的编译器必须一致。
通过phpinfo()查看Thread Safety为enabled则为线程安全版。
通过phpinfo()查看Compiler项可以知道使用的编译器。本人的为:MSVC9 (Visual C++ 2008)。
一、下载pthreads扩展
下载地址:http://windows.php.net/downloads/pecl/releases/pthreads
二、安装pthreads扩展
复制php_pthreads.dll 到目录 bin\php\ext\ 下面。
复制pthreadVC2.dll 到目录 bin\php\ 下面。
复制pthreadVC2.dll 到目录 C:\windows\system32 下面。
打开php配置文件php.ini。在后面加上extension=php_pthreads.dll
提示!Windows系统需要将 pthreadVC2.dll 所在路径加入到 PATH 环境变量中。我的电脑--->鼠标右键--->属性--->高级--->环境变量--->系统变量--->找到名称为Path的--->编辑--->在变量值最后面加上pthreadVC2.dll的完整路径(本人的为C:\WINDOWS\system32\pthreadVC2.dll)。
三、添加thread类
<?php <br />class Thread<br>{<br><br> var $hooks = array();<br> var $args = array();<br><br> function thread()<br> {<br><br> }<br><br> function addthread($func)<br> {<br> $args = array_slice(func_get_args(), 1);<br> $this->hooks[] = $func;<br> $this->args[] = $args;<br> return true;<br> }<br><br> function runthread()<br> {<br> if(isset($_GET['flag']))<br> {<br> $flag = intval($_GET['flag']);<br> }<br> if($flag || $flag === 0)<br> {<br> call_user_func_array($this->hooks[$flag], $this->args[$flag]);<br> }<br> else<br> {<br> for($i = 0, $size = count($this->hooks); $i {<br> $fp=fsockopen($_SERVER['HTTP_HOST'],$_SERVER['SERVER_PORT']);<br> if($fp)<br> {<br> $out = "GET {$_SERVER['PHP_SELF']}?flag=$i HTTP/1.1rn";<br> $out .= "Host: {$_SERVER['HTTP_HOST']}rn";<br> $out .= "Connection: Closernrn";<br> fputs($fp,$out);<br> fclose($fp);<br> }<br> }<br> }<br> }<br>}<br><br><br>
四、测试pthreads扩展
include('thread.php');<br>class AsyncOperation extends Thread {<br> public function __construct($arg){<br> $this->arg = $arg;<br> }<br><br> public function run(){<br> if($this->arg){<br> printf("Hello %s\n", $this->arg);<br> }<br> }<br>}<br>$thread = new AsyncOperation("World");<br>if($thread->start())<br> $thread->join();<br><br><br>

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
