How can the use of foreach loops improve the readability and efficiency of PHP code compared to traditional for loops?

Using foreach loops can improve the readability of PHP code by simplifying the syntax and making it easier to understand the purpose of the loop. Additionally, foreach loops are more efficient than traditional for loops when iterating over arrays or collections in PHP. This is because foreach loops automatically handle the iteration process without the need for manual indexing or incrementing. 

// Traditional for loop
$numbers = [1, 2, 3, 4, 5];
for ($i = 0; $i < count($numbers); $i++) {
    echo $numbers[$i] . "\n";
}

// Using foreach loop
$numbers = [1, 2, 3, 4, 5];
foreach ($numbers as $number) {
    echo $number . "\n";
}
