What are some best practices for handling multiple values in PHP variables?

When handling multiple values in PHP variables, it is best practice to use arrays to store the values. This allows for easy iteration, manipulation, and organization of the data. By using arrays, you can store multiple values in a single variable and access them using keys or indexes. 

// Storing multiple values in an array variable
$fruits = ['apple', 'banana', 'orange'];

// Accessing individual values in the array
echo $fruits[0]; // Output: apple
echo $fruits[1]; // Output: banana
echo $fruits[2]; // Output: orange

// Iterating through the array
foreach ($fruits as $fruit) {
    echo $fruit . ' '; // Output: apple banana orange
}
