codeigniter 4 is returning 1 after include, include_once, require, require_once

Question

When i'm using the above mentioned (include, include_once, require, require_once) methods i'm getting the 1 written at the end of every content where i've used it.

Have a look:

PHP Code:
<!--Footer Section Starts Here-->
    <?= require_once("elements/footer.php"); ?>
<!--Footer Section Ends Here-->

<!--Bottom CSS and JS Starts Here-->
    <?= include_once("elements/bottom_css_and_js.php"); ?>
<!--Bottom CSS and JS Ends Here-->

You need to provide php code, not browser output. Perhaps you use include so it evaluates to boolean, like in example 4 on https://www.php.net/manual/en/function.include.php but it is hard to tell without code. — Sergiy T., May 21 '21 at 10:18
I think you should replace `= require_once("elements/footer.php"); ?>` with ``. `= ?>` is short for `` (https://www.php.net/manual/en/function.echo.php). So it returns true which converted to 1 on output. — Sergiy T., May 21 '21 at 13:16
I thinks its from the environment but it is in the 'production' mode. — Adarsh Kumar, May 21 '21 at 13:30

This is to expand on @sergiy T's comment(answer) and the OP's comment, "Nope it's not working..."

The current code is

<!--Footer Section Starts Here-->
    <?= require_once("elements/footer.php"); ?>
<!--Footer Section Ends Here-->

<!--Bottom CSS and JS Starts Here-->
    <?= include_once("elements/bottom_css_and_js.php"); ?>
<!--Bottom CSS and JS Ends Here-->

Where you are echoing the result of the calls to require_once and include_once etc due to using <?= which is the short code form for <?php echo. So you will see the code being "included" and also the result of the function call which is 1.

So you need to remove the echo's as performing a require or include puts the code inline to be executed/displayed.

So you need to change it to...

<!--Footer Section Starts Here-->
    <?php require_once("elements/footer.php"); ?>
<!--Footer Section Ends Here-->

<!--Bottom CSS and JS Starts Here-->
    <?php include_once("elements/bottom_css_and_js.php"); ?>
<!--Bottom CSS and JS Ends Here-->

As always its advisable to read what these functions do in php.net

Thank You, it's working. I didn't spotted that i'm printing it. — Adarsh Kumar, May 21 '21 at 17:00
