What are the advantages of using arrays instead of numerical variables in PHP programming?

Using arrays instead of individual numerical variables in PHP programming allows for more efficient storage and manipulation of data. Arrays can store multiple values in a single variable, making it easier to iterate over and perform operations on a set of numerical values. Additionally, arrays can be easily passed as arguments to functions, making code more modular and reusable. 

// Example of using arrays instead of numerical variables
$numbers = [1, 2, 3, 4, 5];

// Iterating over the array and performing operations
foreach ($numbers as $number) {
    echo $number * 2 . "\n";
}
