What is array and the the use of it?can someone explain to me?

[★Cooldude★]

An array is used as an alternative to using multiple variables to hold values.

PHP Code:

<?PHP

$array = ("One", "Two", "Three"); //Define the array
Echo $array[0]; //Will echo "One"
Echo $array[2]; //Will echo "Three"

foreach ($array as $value){
Echo "$value, "; //Will echo "One, Two, Three, "
}
?>
