为什么很多人说php不适合开发大型网站但很多大型网站用php开发?
网站说,"PHP不适合开发大型网站,因为:
1)对递归的不良支持
2)许多PHP模块都不是线程安全的
3)PHP 由于商业原因而不健全
4)没有命名空间
5)不标准的日期格式字符
6)混乱的许可证
7)不一致的函数命名规则
8)魔法引用的地狱
9)缺少标准框架,如MVC"
但很多大型网站是用php做的,为什么呢?
"Google(以前是php,后来换python了?),
facebook(历史遗留,一部分换成python了),
亚马逊(www.amazon.com),
mysql.com,
php.net,
百度(前端用php,后台核心都用C/C++),
优酷,
腾讯,
51job.com,
DEDECMS(织梦)
sohu.com(前端用php,后端还是java/c++做),
sina.com,
163.com,
tom.com,
YAHOO.com,
阿里巴巴,
美国国家宇航局NASA,民用信息发布系统等, "

第二条确实有问题,其他都不是问题!

现在有“混合语言开发”一词。
php在表现层表现还是出众的,开发很高效,快捷。
c/c++能操作mysql,php也能操作mysql,拿百度来说,用c/c++采集,用php表现。
大公司会用很多开发语言和工具,对高手来说,开发语言从来不是问题(包括现学)。

刚看了个图,大家一起分享一下 哈哈

php学习成本很低,和C基本是一样的东西,但是反而多了很多方便的库,所以对于性能要求低的程序都可以拿PHP开发,不仅仅是拿来写CGI而已。

MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

Composer is a dependency management tool for PHP, and manages project dependencies through composer.json file. 1) parse composer.json to obtain dependency information; 2) parse dependencies to form a dependency tree; 3) download and install dependencies from Packagist to the vendor directory; 4) generate composer.lock file to lock the dependency version to ensure team consistency and project maintainability.

Installing MySQL on macOS can be achieved through the following steps: 1. Install Homebrew, using the command /bin/bash-c"$(curl-fsSLhttps://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)". 2. Update Homebrew and use brewupdate. 3.
