Swift语言是一门仅仅次于PHP这门最好语言，没有这一的老二语言,弥补PHP的不足。
[调侃苹果]Swift语言是一门仅仅次于PHP这门最好语言，没有这一的老二语言,弥补PHP的不足。当然Swift也确实可以去做Ios开发。。
背景：Swift是静态语言?听说这门子语言linux也默认安装支持啦啊，开源中国要用Swift重写整个网站了。Swift静态语言 + PHP动态语言，绝妙的组合。当然了。Swift性能很强的。
定位：Swift是静态语言，和Rust定位差不多的。系统级语言?胡说，无稽之谈,操作系统层面完全可以替换C，Swift可以直接导入C库，它还很胶水，能打能退，边打边跑，性格倔强。
概论：可以取代C来写一些底层软件，c写程序效率有点慢，不管怎么说，swift只是一门语言，作者的另外一个作品是LLVM，Swift的性能差不多是 C的50%左右，内存模型和C几乎一致。有人问swift 能搞底层吗？！完全可以。
比肩语言：GO语言个人觉得意义不大，标榜自己是系统级语言，实际上是个应用层语言，和PHP来抢市场。之前说 GO是替代C语言的 现在 swift又是替代GO的，swift 跟Go都是偏应用层，swift的作者年轻而go的作者有点老。
极客语言：Golang的语法也确实不是特别友好，比较Geek，Go语言的作者是以前Plan9那帮人搞的，go作者是超级大师级，大师毕竟是少数，人人不可能成大湿。
回归本质：c 是内功， 其他都是招式。C语言最朴实。随便拿个C的开源项目过来，只要你有C的功底都能改改。继续做二次开发。其他的语言，像PHP，Java，Go，C++ 你不花点时间研究下这个项目，完全上不了手。
结论，学不过来了 还是好好 学 PHP把 PHP才是世界最好的语言， PHP就你们这群老家伙在玩 新人也不少，不玩PHP玩什么,能赚钱就行 管他什么语言.

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.
