What is an Array?
An array is a special variable, which can hold more than one value at a time.
For example: if you have a list of items (mobile phone name), storing the mobile phone in single variables could look like this:
$mobile-phone1 = "iPhone";
$mobile-phone2 = "Samsung";
$mobile-phone3 = "Nokia";
$mobile-phone4 = "LG";
However, what if you want to loop through the mobile-phone and find a specific one? And what if you had not 4 mobile-phone, but 250?
Solution is to create an array
An array can hold many values under a single name, and you can access the values by referring to an index number.

Create an Array in PHP - how? - example


In PHP, the array() function is used to create an array.
In PHP language, there are three types of arrays:
Indexed arrays - numeric index,
Associative arrays - named keys,
Multidimensional arrays - containing one or more arrays


Example 1: PHP Indexed Arrays

<?php
$mobile-phone = array("iPhone", "Samsung", "Nokia", "LG");
echo "I like " . $mobile-phone[0] . ", " . $mobile-phone[1] . ", " . $mobile-phone[2] . " and " . $mobile-phone[3] . ".";
?>

PHP cod above will display this result -

css border radius

Note: In an indexed or numeric array, the indexes are automatically assigned and start with 0, and the values can be any data type.

PHP Associative Arrays - How to create

PHP Associative Arrays
Associative arrays are arrays that use named keys that you assign to them.
There are two ways to create an associative array:

Example 2:
<?php
$mobile-phone = array("Nick"=>"38", "George"=>"39", "Paul"=>"42");
echo "George is ". $age['George'] ." years old.";
?>

The PHP cod above will display this result -

css borderradius

Multidimensional arrays will be explained in the PHP advanced section.
