How to use foreach() in php

foreach in php only applies to arrays and is used to traverse each key-value pair in the array. The syntax of the foreach loop statement is "foreach ($array as $value) {code to be executed;}".

##Usage of foreach() in php:

foreach loop only applies to arrays, and used to iterate over each key/value pair in the array.

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

Each loop iteration is performed, the value of the current array element will be assigned to the $value variable, and the array pointer will move one by one until the last array element is reached.

Example:

The loop will output the value of the given array ($colors):

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