What is the `Array.prototype.forEach` method in JavaScript?
`Array.prototype.forEach` executes a provided function once for each element in the array. It does not return a value and does not modify the original array. const arr = [1, 2, 3]; arr.forEach(num => console.log(num)); // Output: // 1 // 2 // 3

What is the 'foreach' loop in PHP?
The `foreach` loop in PHP is used to iterate over arrays. It provides a simple way to loop through all elements in an array without the need for an index. The syntax is: `foreach ($array as $value) { // code to execute }`. For associative arrays, use: `foreach ($array as $key => $value) { // code to execute }`. This loop is particularly useful for accessing each element of an array directly.
