how does foreach works in php code example

Example 1: php foreach

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

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

Example 2: for each loop php

<?php 
$colors = array("red", "green", "blue", "yellow"); 

 
foreach ($colors as $value) {
  echo "$value <br>";
}
?>
