How can initializing arrays in PHP prevent errors like "Undefined variable" and "Undefined offset"?

When working with arrays in PHP, initializing them before use can prevent errors like "Undefined variable" and "Undefined offset" because it ensures that the array exists with defined keys. This means that you won't be trying to access or manipulate a non-existent array, which would trigger these errors. 

// Initializing an empty array to prevent "Undefined variable" and "Undefined offset" errors
$myArray = [];

// Adding elements to the array
$myArray[] = "element1";
$myArray[] = "element2";

// Accessing elements in the array
echo $myArray[0]; // Output: element1
