Running PHP scripts requires the following steps: 1. Make sure that the server is installed and enabled, and Linux can be installed and checked with the version; 2. Place the .php file in the root directory of the server document such as /var/www/html/ or C:\xampp\htdocs\; 3. Configure Apache or Nginx to handle PHP requests, enable the module or use PHP-FPM if necessary; 4. Set correct permissions and adjust the error prompts to ensure security. After completing the above steps, restart the service and access the execution results through the browser.
Running PHP scripts is not complicated, but novices are prone to encounter some problems when they first configure them. As long as the server environment is built correctly and the basic execution process is understood, the PHP program can be run smoothly.

Ensure the server supports PHP
First, you need to confirm whether your server has PHP installed and enabled. Most virtual hosts support PHP by default, but if you build your own server (such as Apache or Nginx), you need to manually install the PHP environment.

- If you are using a Linux system, you can install PHP through the command line, for example, it can run on Ubuntu:
sudo apt update sudo apt install php
- After the installation is complete, check whether PHP is running normally and enter:
php -v
If you see the version number output, it means that PHP has been installed successfully.
Put the PHP file in the correct directory
Different server configurations may store web page files in different locations, common ones such as:

- Apache default path:
/var/www/html/
- XAMPP on Windows is usually:
C:\xampp\htdocs\
You need to put the .php
file into these directories to access it through the browser. For example, you created a test.php
file with the following content:
<?php echo "Hello, world!"; ?>
After putting it into the server document root directory, access it in the browser:
http://localhost/test.php
You can see the output result.
Configure the server to handle PHP requests
If you are using Apache, usually just make sure the mod_php
module is enabled. If it is Nginx, it needs to be used with PHP-FPM.
- Common Apache configuration file location:
/etc/apache2/sites-available/000-default.conf
- Nginx configuration sample snippet:
location ~ \.php$ { include snippets/fastcgi-php.conf; fastcgi_pass unix:/run/php/php8.1-fpm.sock; }
Remember to restart the service after modifying the configuration:
sudo systemctl restart apache2 # or sudo systemctl restart nginx
This way the server can correctly parse PHP files.
Pay attention to permissions and security settings
PHP scripts may operate on files, databases and other resources, so permission settings are important.
- Make sure that the website directory has read permissions, but do not open global write permissions.
- Do not place sensitive configuration files in web-accessible directories.
- Error prompts can be enabled in the development environment:
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL);
But it must be closed before going online.
Basically these steps. It doesn't seem complicated, but it's easy to make mistakes at a certain step, especially when configuring the server. Just try a few more times and become familiar with the entire process, it will become natural to run PHP scripts.

Common problems and solutions for PHP variable scope include: 1. The global variable cannot be accessed within the function, and it needs to be passed in using the global keyword or parameter; 2. The static variable is declared with static, and it is only initialized once and the value is maintained between multiple calls; 3. Hyperglobal variables such as $_GET and $_POST can be used directly in any scope, but you need to pay attention to safe filtering; 4. Anonymous functions need to introduce parent scope variables through the use keyword, and when modifying external variables, you need to pass a reference. Mastering these rules can help avoid errors and improve code stability.

To safely handle PHP file uploads, you need to verify the source and type, control the file name and path, set server restrictions, and process media files twice. 1. Verify the upload source to prevent CSRF through token and detect the real MIME type through finfo_file using whitelist control; 2. Rename the file to a random string and determine the extension to store it in a non-Web directory according to the detection type; 3. PHP configuration limits the upload size and temporary directory Nginx/Apache prohibits access to the upload directory; 4. The GD library resaves the pictures to clear potential malicious data.

There are three common methods for PHP comment code: 1. Use // or # to block one line of code, and it is recommended to use //; 2. Use /.../ to wrap code blocks with multiple lines, which cannot be nested but can be crossed; 3. Combination skills comments such as using /if(){}/ to control logic blocks, or to improve efficiency with editor shortcut keys, you should pay attention to closing symbols and avoid nesting when using them.

The key to writing PHP comments is to clarify the purpose and specifications. Comments should explain "why" rather than "what was done", avoiding redundancy or too simplicity. 1. Use a unified format, such as docblock (/*/) for class and method descriptions to improve readability and tool compatibility; 2. Emphasize the reasons behind the logic, such as why JS jumps need to be output manually; 3. Add an overview description before complex code, describe the process in steps, and help understand the overall idea; 4. Use TODO and FIXME rationally to mark to-do items and problems to facilitate subsequent tracking and collaboration. Good annotations can reduce communication costs and improve code maintenance efficiency.

In PHP, you can use square brackets or curly braces to obtain string specific index characters, but square brackets are recommended; the index starts from 0, and the access outside the range returns a null value and cannot be assigned a value; mb_substr is required to handle multi-byte characters. For example: $str="hello";echo$str[0]; output h; and Chinese characters such as mb_substr($str,1,1) need to obtain the correct result; in actual applications, the length of the string should be checked before looping, dynamic strings need to be verified for validity, and multilingual projects recommend using multi-byte security functions uniformly.
