What is the significance of correctly formatting array elements in PHP to avoid errors?

Correctly formatting array elements in PHP is important to avoid errors because PHP is a loosely typed language, meaning that it can interpret data types differently depending on how they are formatted. By explicitly specifying the data type of array elements, we can prevent unexpected behavior and ensure that our code runs smoothly. This can help prevent issues such as type coercion errors or unexpected results when working with arrays in PHP.

// Incorrect way of defining array elements without specifying data types
$myArray = [1, '2', true, 'four'];

// Correct way of defining array elements with specified data types
$myArray = [1, (int)'2', true, 'four'];
