Can the behavior of PHP regarding uninitialized variables be forced to trigger warnings in versions higher than 5.1?

In PHP versions higher than 5.1, the behavior of uninitialized variables can be forced to trigger warnings by setting the error_reporting level to include E_NOTICE. This will ensure that any use of uninitialized variables will be flagged as a notice, prompting developers to initialize variables before using them to avoid unexpected behavior or bugs in their code. 

<?php
error_reporting(E_ALL & ~E_NOTICE);

$uninitializedVariable; // This will trigger a notice

echo $uninitializedVariable; // This will also trigger a notice

// Initialize the variable to prevent notices
$initializedVariable = "Hello, World!";
echo $initializedVariable;
?>
