Remember, when using require that it is a statement, not a function. It's not necessary to write:
<?php
require('somefile.php');
?>
The following:
<?php
require 'somefile.php';
?>
Is preferred, it will prevent your peers from giving you a hard time and a trivial conversation about what require really is.
require
require는 실패시에 치명적인
E_ERROR 등급 오류가 발생한다는 점을 제외하면,
include와 동일합니다. 즉,
include가 경고(E_WARNING)만
발생하고 스크립트는 계속 진행되는 것과 달리, 스크립트가 중단됩니다.
작동에 관해서는 include 문서를 참고하십시오.

If your included file returns a value, you can get it as a result from require(), i.e.
foo.php:
<?php
return "foo";
?>
$bar = require("foo.php");
echo $bar; // equals to "foo"

Always use __DIR__ to define path relative to your current __FILE__.
(Or another setting that is originally based on __DIR__/__FILE__)
try & catch - don't get confused by the words "fatal E_COMPILE_ERROR" - it's still just an internal Error that implements Throwable - it can be caught:
<?php
try {
require(__DIR__ . '/something_that_does_not_exist');
} catch (\Throwable $e) {
echo "This was caught: " . $e->getMessage();
}
echo " End of script.";
?>
Note that this will still emit a warning "Failed to open stream: No such file or directory..." ...unless you prefix the require with "@" - which I strongly don't recommend as it would ignore/supress any diagnostic error (unless you have specified set_error_handler()). But even if you'd prefix the require with "@" it would still be caught.
