windows可以么? windows不可以么?

简介

PHP的进程控制支持实现了Unix方式的进程创建, 程序执行, 信号处理以及进程的中断。 进程控制不能被应用在Web服务器环境,当其被用于Web服务环境时可能会带来意外的结果。 

这份文档用于阐述每个进程控制函数的通常用法。关于Unix进程控制的更多信息建议您查阅 系统文档中关于fork(2),waitpid(2),signal(2)等的部分或更全面的参考资料比如 《Unix环境高级编程》(作者:W. Richard Stevens,Addison-Wesley出版)。 

PCNTL现在使用了ticks作为信号处理的回调机制,ticks在速度上远远超过了之前的处理机制。 这个变化与“用户ticks”遵循了相同的语义。您可以使用 declare()语句在程序中指定允许发生回调的位置。这使得我们对异步事件处理的开销最小化。在编译PHP时 启用pcntl将始终承担这种开销,不论您的脚本中是否真正使用了pcntl。 

有一个调整是PHP 4.3.0之前的所有pcntl脚本要使其工作,要么在期望允许回调的(代码)部分使用 declare() ,要么使用 declare()新的全局语法 使其在整个脚本范围有效。 


Note: 此扩展在 Windows 平台上不可用。

windows是不支持pcntl_fork的!

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
