PHP Foreach Loop

The foreach loop works only on arrays, and is used to loop through each key/value pair in an array.

Syntax

    foreach ($array as $value) {
        code to be executed;
      }

For every loop iteration, the value of the current array element is assigned to $value and the array pointer is moved by one, until it reaches the last array element.

The following example will output the values of the given array ($colors):

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

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

red
green
blue
yellow
