Foreach Statement in php

Foreach statement in php programming language. For Each statement refer to for each loop because it does loop through elements of array and allow as to each array over an array it take out different elements. Here i will use Multi-dimensional arrays with help of foreach statement i will display list of healthy and unhealthy foods.

<?php



$food = array('Healthy'=>array ('salad',Vegetables','Pasta');

'Unhealthy'=>array('Pizza','ice cream'));

echo $element.'
';

}

?>

In this example we will see practical use of Multi-dimensional arrays and then using this foreach statement to basically display there values. With keyword foreach we need to address array which is $food as $element. So, $food as

$element is taking which is healthy and unhealthy. $food as $element => $inner_element now in this $element is healthy and unhealthy and $inner_element addresses to array of  healthy and unhealthy such as salad, vegetables, pasta, pizza and ice cream. As you see output of $element is healthy and unhealthy. So, we had categorized two different element of array food. If i want inner_element of the array echo out here it will only display array. To find information about inner_element we need to loop again we already loop to find information of food array which is healthy and

unhealthy now for array of healthy and unhealthy we need to loop again.
