What are the implications of omitting the initialization of a variable like $i=0 at the beginning of PHP code and how can it impact the script's functionality?

Omitting the initialization of a variable like $i=0 at the beginning of PHP code can lead to unexpected behavior and errors in the script. It can result in using a variable that has not been properly initialized, leading to undefined behavior or incorrect results. To avoid this issue, it is important to always initialize variables before using them in PHP. 

<?php

// Initialize the variable $i to 0
$i = 0;

// Rest of the PHP code goes here

?>
