What are the best practices for combining different loops in PHP?

When combining different loops in PHP, it is important to ensure that the loops do not interfere with each other and that the logic of each loop is clear and concise. One common approach is to nest loops within each other, ensuring that the inner loop completes its iterations before moving on to the next iteration of the outer loop. Another approach is to use different loop structures, such as a foreach loop within a for loop, to achieve the desired functionality. 

// Example of combining a for loop with a foreach loop
$numbers = [1, 2, 3, 4, 5];
$letters = ['A', 'B', 'C', 'D', 'E'];

for ($i = 0; $i < count($numbers); $i++) {
    echo "Number: " . $numbers[$i] . "\n";
    
    foreach ($letters as $letter) {
        echo "Letter: " . $letter . "\n";
    }
}
