PHP scripts are written in plain text files. The file name for a PHP script typically ends with the “.php” extension. This convention helps web servers recognize files that contain PHP code and ensure that they are processed appropriately by the PHP interpreter. For example, you might have files named “index.php”, “script.php”, or “contact.php”, depending on the functionality and purpose of the script.

PHP doesn’t have strict naming conventions for PHP files, but there are some common practices and recommendations that developers often follow. It’s always a good idea to follow these conventions to make your code more understandable for yourself and other developers who may work on the project.

Use lowercase

It’s common to use lowercase letters for PHP file names. This helps maintain consistency and is easier to work with, especially if your project is hosted on a case-sensitive file system.

Use underscores or hyphens for readability

If the file name contains multiple words, you can separate them with underscores (_) or hyphens (-) to improve readability. For example, php_script.php or php-script.php.

Use meaningful names

Choose file names that are descriptive and indicative of the file’s purpose or contents. This makes it easier for developers to understand what each file does without having to open it.

Use the .php extension

PHP files should always have the “*.php” extension to indicate that they contain PHP code. This helps web servers recognize and properly interpret the PHP code within the file.

Conclusion

Consistency plays a crucial role in software projects. It promotes readability, maintainability, and collaboration among developers. When coding styles, naming conventions, and architectural patterns are consistent throughout a project, it becomes easier for team members to understand and contribute to the codebase effectively.
