how does a foreach loop work in php code example

Example 1: php foreach

$arr = ['Item 1', 'Item 2', 'Item 3'];

foreach ($arr as $item) {
  var_dump($item);
}

Example 2: foreach in php

<?php
// Declare an array 
$arr = array("green", "blue", "pink", "white");  
  
// Loop through the array elements 
foreach ($arr as $element) { 
    echo "$element "; 
} 
?>
