php require vs require_once
//The require statement has two variations, require and require_once.
//The require/require_once statement is used to include file.
// Require a file to be imported or quit if it can't be found
<?php
require 'requiredfile.php';
?>
// Require_once is ignored if the required file has already been added by any of the include statements.
<?php
require_once 'require_oncefile.php';
?>

As there is two different kind of require statements i.e. require and require_once
both are having same functionality of including file into the another.
Using require if the file is not misplaced or undefined then its stops the execution of the document.
<?php
require 'requiredfile.php';
?>
And require_once is gets ignored if the file already imported with any other require or require_once.
<?php
require_once 'require_oncefile.php';
?>
Thank you!
