PHP files can be accessed and executed in a number of ways. Here are a few common examples:
Via a web server: This is the most common way PHP files are accessed. When a user visits a webpage that’s built with PHP, the web server processes the PHP code and sends the resulting output (typically HTML) to the user’s browser. For example, if a user visits
index.phpfile will be processed by the server and the resulting HTML will be sent to the user’s browser.
Via command line interface (CLI): PHP files can also be executed directly from the command line, much like scripts written in other languages like Python or Ruby. This can be useful for running scripts or tasks that don’t need to interact with a web server. To do this, you would navigate to the directory containing the PHP file using the command line, and then execute the file using the PHP interpreter, like so:
Via a web-based file manager: Many hosting providers offer web-based file managers (like cPanel’s File Manager) that allow you to access and edit your PHP files directly through the browser. This can be a convenient way to make quick edits to your PHP files, although it’s generally recommended to use a dedicated text editor or IDE for larger projects.
Via FTP/SFTP: You can access and edit your PHP files by connecting to your server via FTP or SFTP. This is done using an FTP client like FileZilla. After connecting to your server, you can download PHP files, edit them on your local machine, and then upload them back to the server.
Remember that PHP is a server-side scripting language. This means that the PHP code itself is never sent to the client; only the output of the PHP code is sent. The PHP code is executed on the server, which generates HTML that’s sent to the client’s browser.
