PHP foreach Loop

PHP foreach Loop

The Foreach loop applies only to arrays and is used to iterate through each key/value pair in the array.

Grammar

foreach ($array as $value) {

code to be executed;

}

For each iteration of the loop, the value of the current array element is assigned to the $value variable, and the array pointer moves one at a time until the last array element is reached.

The following example shows a loop that outputs the value of a given array ($colors):

Instance

<?php $colors = Array ("Red", "green", "blue", "yellow"); foreach ($colors as $value) {  echo "$value <br>";}? >
