What is the purpose of using a function in PHP and how can it be implemented in a foreach loop?

Using a function in PHP allows you to encapsulate a block of code that can be reused multiple times throughout your program. This can help to improve code readability, maintainability, and reusability. To implement a function within a foreach loop, you can define the function outside of the loop and then call it within the loop to perform a specific task on each element of the array. 

// Define a function to perform a specific task
function processElement($element) {
    // Code to process each element
    echo "Processing element: $element <br>";
}

// Array to iterate over
$items = [1, 2, 3, 4, 5];

// Iterate over the array using a foreach loop
foreach ($items as $item) {
    // Call the function to process each element
    processElement($item);
}
