首先,c语言并不是啥也干不了,只是你的应用场合不对,其次对于php来说,c语言可以写它的拓展
可以看看这个,用C/C++拓展你的PHP
既然是写惯了PHP的人,初碰C语言,大概应该先玩玩CGI吧。CGI要玩其实很简单,把下面这个编译出来的可执行文件改名作test.cgi
放到配置好的Apache的bin-cgi目录下面,然后访问http://localhost/bin-cgi/test.cgi
就好:
<code>// cflags: -o /var/www/cgi-bin/test.cgi #include <stdio.h> #include <stdlib.h> #include <string.h> int main() { printf("Content-Type: text/plain\n\n"); char *qs = getenv("QUERY_STRING"); if(!qs) exit(-1); char* equ = strchr(qs, '='); if(equ) *(equ++) = '\0'; if(strcmp(qs, "name")) printf("Parameters incorrect."); else printf("Hello Mr./Mrs. %s", equ); return 0; }</string.h></stdlib.h></stdio.h></code>
光学c当然啥也干不了,最多写个控制台计算器之类的而已。
c要和系统api结合起来,才能干些事情,不过说到底,这些功劳都是系统api的,与c关系不大。
结论你说的很对,学完c啥也干不了
你可以写个数据库,当然这个要结合系统API
学完C之后就可以很好的理解PHP的底层,对一些原来只知道用的东西能更好的理解它的原理
哎 说C语言啥都干不了?反过来说才对 C语言不能干什么
大神约翰卡马克的游戏引擎都是纯C的
C语言 能干什么 不重要 学编程C能让你彻底理解内存~彻底学会从程序的角度思考问题~
这时才是最重要的
你应该问:怎样才能用c做事?
php就是c写的,你说呢?
请用合适的语言做合适的事情
c语言特别适合写操作系统等性能要求较高的地方
这些地方要求c语言运行时尽可能小 所以c语言只用标准库真的是什么也干不了
不过操作系统 导出的api都是c语言的借口
买本 unix网络高级编程第一卷 或者 unix环境高级编程 看看 会有很大的帮助的

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
