为PHP设置服务器(Apache/Nginx)环境变量
设置环境变量常见的地方为区分开发环境/生产环境,或者定义一些数据库的帐号密码 设置Apache环境变量 指令 设置当前环境变量为 DEV SetEnv RUNTIME_ENVIROMENT DEV 数据库帐号密码 SetEnv MYSQL_USERNAME rootSetEnv MYSQL_PASSWORD root 配置文件格式 Virtu
设置环境变量常见的地方为区分开发环境/生产环境,或者定义一些数据库的帐号密码
设置Apache环境变量
指令
设置当前环境变量为DEV
<code>SetEnv RUNTIME_ENVIROMENT DEV </code>
数据库帐号密码
<code>SetEnv MYSQL_USERNAME root SetEnv MYSQL_PASSWORD root </code>
配置文件格式
<code><virtualhost> ServerAdmin admin@admin.com DocumentRoot "/var/www/" ServerName localhost SetEnv RUNTIME_ENVIROMENT DEV SetEnv MYSQL_USERNAME root SetEnv MYSQL_PASSWORD root ErrorLog "logs/error.log" CustomLog "logs/access.log" common </virtualhost> </code>
设置Nginx环境变量
指令
设置当前环境变量为DEV
<code>fastcgi_param RUNTIME_ENVIROMENT 'DEV' </code>
数据库帐号密码
<code>fastcgi_param MYSQL_USERNAME 'root' fastcgi_param MYSQL_PASSWORD 'root' </code>
配置文件格式
在fastcgi_params文件中配置
<code>fastcgi_param RUNTIME_ENVIROMENT 'DEV'; fastcgi_param MYSQL_USERNAME 'root'; fastcgi_param MYSQL_PASSWORD 'root'; </code>
在nginx.conf中配置
<code>server { listen 80; root /var/www; index index.php; server_name localhost; location / { index index.php; } location ~ .*\.(php|php5)?$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi_params; } } </code>
为PHP脚本设置环境变量
为当前用户临时设置
临时设置只需要执行
<code>export KEY=VALUE </code>
为当前用户永久设置
在~/.bashrc
(不同系统各有不同)中写
为所有用户(不包括root)设置
创建文件/etc/profile.d/test.sh
,写入
<code>KEY=VALUE </code>
为所有用户(包括root)设置
在/etc/environment
中写入
<code>KEY=VALUE </code>
注意,这个文件的生效时间是用户登录时,所以对于root来说,需要重启机器
在Supervisor中设置
有的时候PHP脚本是用Supervisor来控制的,所以记得设置supervisor配置中的environment项
在PHP中调用服务器环境变量
在PHP中有两个调用方式:
<code>$env = getenv('RUNTIME_ENVIROMENT'); </code>
还有超全局变量方式:
<code>$env = $_SERVER['RUNTIME_ENVIROMENT']; </code>

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

You can query the Docker container name by following the steps: List all containers (docker ps). Filter the container list (using the grep command). Gets the container name (located in the "NAMES" column).

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.
