关于gzip?
请问gzip压缩的是什么？？仅仅是压缩代码？还是说代码中的远程资源如：jpg,js文件也会被压缩？
他大概的实现原理是什么?

G-ZIP 参考 apache 的 mod_deflate
原文：http://httpd.apache.org/docs/current/mod/mod_deflate.html
中文：http://www.phpchina.com/resource/manual/apache/mod/mod_deflate.html
至于CSS，JS，自己关键字搜索：
CSS Minifier
JavaScript Minifier
现在网络那么发达，没有找不到的答案，只有你不肯找。
我们在Linux中经常会用到后缀为.gz的文件，它们就是GZIP格式的。现今已经成为Internet 上使用非常普遍的一种数据压缩格式，或者说一种文件格式。
HTTP协议上的GZIP编码是一种用来改进WEB应用程序性能的技术。大流量的WEB站点常常使用GZIP压缩技术来让用户感受更快的速度。这一般是指WWW服务器中安装的一个功能，当有人来访问这个服务器中的网站时，服务器中的这个功能就将网页内容压缩后传输到来访的电脑浏览器中显示出来.一般对纯文本内容可压缩到原大小的40%.这样传输就快了，效果就是你点击网址后会很快的显示出来.当然这也会增加服务器的负载. 一般服务器中都安装有这个功能模块的。
希望能帮到你
提高服务器性能的一种技术。

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.
