Are there any best practices for declaring and initializing variables in PHP to avoid errors like the one mentioned in the thread?

The issue mentioned in the thread could be avoided by following best practices when declaring and initializing variables in PHP. One common best practice is to always initialize variables before using them to prevent errors like "Undefined variable." Additionally, it's recommended to use strict type declarations to ensure that variables have a specific type. 

<?php
// Declare and initialize variables
$name = "John";
$age = 25;
$isAdmin = true;

// Using strict type declaration
declare(strict_types=1);

// Declare and initialize variables with specific types
int $num1 = 10;
string $str1 = "Hello";
bool $flag = false;
?>
