What are the potential pitfalls of not having a clear schema when working with arrays in PHP?

Without a clear schema when working with arrays in PHP, it can be challenging to maintain consistency and structure in your data. This can lead to errors in accessing or manipulating array elements, as well as difficulty in understanding the data structure. To avoid these pitfalls, it is important to define a clear schema for your arrays, outlining the expected keys and data types for each element. 

// Define a clear schema for the array
$schema = [
    'name' => 'string',
    'age' => 'int',
    'email' => 'string'
];

// Example of using the schema to create a structured array
$user = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
];
