How can the use of foreach loops improve the efficiency and readability of array operations in PHP?

Using foreach loops can improve the efficiency and readability of array operations in PHP by simplifying the code and reducing the chances of errors. By iterating over each element in an array, foreach loops make it easier to perform operations on each item without the need for manual index tracking. This can lead to cleaner and more concise code, making it easier to understand and maintain. 

// Example of using foreach loop to iterate over an array and perform operations
$numbers = [1, 2, 3, 4, 5];
foreach ($numbers as $number) {
    echo $number * 2 . " "; // Multiply each number by 2 and output the result
}
