http_response_code - PHP code example

The PHP Function http_Response_Code

PHP is a popular server-side scripting language used to build dynamic web applications and websites. It is interpreted and not compiled, making it fast and easy to learn. It can manipulate data, connect to databases, handle form data, generate dynamic page content, and much more. It can also prevent cached pages and help to ensure that only the most recent version of your website is being displayed to users.

The php function http_response_code is used to set the HTTP status code for a particular request. It accepts a string and an int as the first arguments, and then returns the result of that calculation. The code below sets the response code to 200 (OK), but you can replace it with any valid HTTP status code that suits your needs.

Note: Alternatively, you can use the header() function in PHP to send a raw HTTP header to the browser. The difference is that the header() function must be called before any output is sent to the browser, whether it is from HTML tags, empty lines in a file, or any other type of PHP output.

In either case, it is recommended to avoid hard-coding the HTTP protocol in the header() function, as this increases the chance of errors. Instead, it is better to use the http_response_code() function in PHP. This way, you can be sure that the status code is being set properly and accurately. It will also be safer in the event of any future changes to the PHP codebase that may affect backwards compatibility with existing sites.
