PHP Arrays

Today lession is how to work with PHP arrays. An array is a variable which can store number of values at once


<?php
$phones = array("nokia","sony","samsung");

echo "Phones : ".$phone[0].",".$phone[1]." and ".$phone[2];


?>

result - Phones : nokia , sony and samsung


We can count number of values in the array using count() function.


<?php
$phones = array("nokia","sony","samsung");

echo "Phones : ".$phone[0].",".$phone[1]." and ".$phone[2];

echo "<br/> Number of values in this array is : ".count($phones);
?>

result - Phones : nokia , sony and samsung
            Number of values in this array : 3


Lets create an Associative arrays

There is no much difference between associative array and normal array but when we work with normal arrays, we retrieve data using index number. but if we use associative array we can use name keys to retrieve data. 

Lets see how to create an associative array.



<?php

$age = array("kasun"=>50,"nimal"=>55,"dasun"=>57)

echo "kasun is : ".$age['kasun']."years old";
?>
