A Php Script Should Start With And Ends With

PHP Programming

When it comes to writing a PHP script, there are a few key things to keep in mind. Not only is it important to ensure that the code is functional, but it’s also essential to follow best practices to maintain clean and organized code. One of the fundamental aspects of a PHP script is the inclusion of the proper opening and closing tags.

First and foremost, every PHP script should start with the opening PHP tag, which is <?php. This tag is what signifies the beginning of PHP code within the script. It’s important to include this tag at the very beginning of the script to inform the server that it should interpret the following code as PHP.

As a developer, I have found that including the opening PHP tag at the start of the script is crucial for ensuring that the PHP interpreter recognizes and processes the code correctly. Omitting this tag can lead to errors and make the script inactive, so it’s a step that should never be overlooked.

On the other end, every PHP script should end with the closing PHP tag, which is ?>. This tag serves to denote the conclusion of the PHP code within the script. It’s imperative to include this tag at the end of the script to clearly define where the PHP code ends.

From my experience, incorporating the closing PHP tag is essential for maintaining well-structured and easily maintainable code. Failing to include this tag can result in unexpected behavior and make it challenging to identify the exact endpoint of the PHP code.

Additionally, it’s important to note that omitting the closing PHP tag at the end of the script is considered a best practice in the PHP community, especially in files that contain only PHP code. This is due to the fact that including the closing tag can potentially lead to unintended whitespace or output, which may cause issues in certain scenarios.

Conclusion

In conclusion, starting a PHP script with <?php and ending it with ?> are essential practices for every PHP developer to follow. These tags not only define the beginning and end of the PHP code within the script but also play a crucial role in ensuring the proper interpretation and execution of the code. By adhering to these guidelines, developers can maintain clean, reliable, and consistent PHP scripts.
