The foreach Loop is used to display the value of array. You can define two parameter inside foreach separated through “as” keyword. First parameter must be existing array name which elements or key you want to display. At the Position of 2nd parameter, could define two variable: One for key(index) and another for value.

if you define only one variable at the position of 2nd parameter it contain arrays value (By default display array value).

Syntax

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

In the following example to list out the values of an array

<?php
 $array = array( 1, 2, 3, 4, 5);
   
 foreach( $array as $value ) {
 echo "Value is $value <br />";
 }
 ?>

The following example demonstrates a loop that will output the values of the given array ($colors)

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

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

Example to find the Sum of given array

<?php
$array=array(10,11,12,13,14,15);
$sum=0;
 foreach ($array as $x)
{
 $sum=$sum+$x;
} 
 echo "Sum of given array = ".$sum;
?>
