What are some best practices for storing and managing arrays in PHP?

When storing and managing arrays in PHP, it is important to properly initialize arrays, access and modify array elements efficiently, and use appropriate array functions for manipulation. It is also recommended to use associative arrays for key-value pairs and multidimensional arrays for nested data structures. 

// Initializing an array
$numbers = [1, 2, 3, 4, 5];

// Accessing and modifying array elements
echo $numbers[0]; // Output: 1
$numbers[2] = 10;

// Using array functions
$fruits = ['apple', 'banana', 'orange'];
array_push($fruits, 'grape');
array_pop($fruits);

// Associative arrays
$person = ['name' => 'John', 'age' => 30];

// Multidimensional arrays
$students = [
    ['name' => 'Alice', 'grade' => 'A'],
    ['name' => 'Bob', 'grade' => 'B']
];
