How can beginners avoid common pitfalls when working with arrays in PHP?

Beginners can avoid common pitfalls when working with arrays in PHP by ensuring they properly initialize arrays before using them, avoiding mixing different data types in the same array, and being mindful of array indexes starting at 0. They should also pay attention to array functions and methods to manipulate arrays effectively. 

// Initializing an empty array before using it
$myArray = array();

// Avoiding mixing different data types in the same array
$numbers = array(1, 2, 3);
$names = array('Alice', 'Bob', 'Charlie');

// Being mindful of array indexes starting at 0
echo $numbers[0]; // Output: 1

// Using array functions and methods to manipulate arrays effectively
array_push($myArray, 'apple', 'banana', 'cherry');
