How can initializing the array $lottery before using it help in avoiding errors in PHP?

Initializing the array $lottery before using it can help avoid errors in PHP by ensuring that the variable is defined and ready to be used. If the array is not initialized before use, PHP may throw an error indicating that the variable is undefined. By initializing the array beforehand, we can prevent these errors from occurring.

// Initializing the array $lottery before using it
$lottery = [];

// Now $lottery is defined and can be used without causing errors
// Example usage:
$lottery[] = 5;
$lottery[] = 10;

// Display the contents of the $lottery array
print_r($lottery);
