多线程 php
在网上看到一些demo,很多一样的,自己拿到本机测试,出了点问题://a.php
function runThread(){
$fp = fsockopen('localhost', 80, $errno, $errmsg);
fputs($fp, "GET /a.php?act=b");
fclose($fp);
}
function a(){
$fp = fopen('result_a.log', 'w');
fputs($fp, 'Set in ' . Date('h:i:s', time()) . (double)microtime() . "\r\n");
fclose($fp);
}
function b(){
$fp = fopen('result_b.log', 'w');
fputs($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($_GET['act'] == 'b') b();
?>
每次我访问localhost/a.php时,只能在result_a.log中写入记录,result_b.log中从来不会写入记录,我确定我的php环境中已经可以启用fsocket扩展了的,求高手指点一下
回复讨论(解决方案)
自挽一下,求大哥们指点
因为你默认的$_GET['act'] 是 执行 a()函数
执行localhost/a.php?act=b试试
php的多线程?
应该是fputs里面的数据包头部些少了什么造成的。
我的意见:
1 使用firebug看看就知道应该写什么,观察你请求的包头
2 放弃fsock系列函数,很多地方都不支持这个,不过你可以使用curl来模拟你的请求。
使用firebug看看错误,或者用echo 检查程序执行到哪了?没执行到哪一步一步的检查。
好吧,该结贴了

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.
