Are there any best practices or guidelines for organizing and manipulating arrays in PHP to avoid unexpected results?

When organizing and manipulating arrays in PHP, it is important to avoid unexpected results by following best practices such as using built-in array functions, properly initializing arrays, and avoiding direct manipulation of array keys. Additionally, it is recommended to use descriptive variable names and comments to make the code more readable and maintainable. 

// Example of organizing and manipulating arrays in PHP

// Initialize an associative array with descriptive keys
$student = [
    'name' => 'John Doe',
    'age' => 20,
    'grade' => 'A'
];

// Access and manipulate array values using built-in functions
echo $student['name']; // Output: John Doe
$student['age']++; // Increment age by 1

// Loop through an array using foreach and avoid direct manipulation of keys
foreach ($student as $key => $value) {
    echo "$key: $value\n";
}
