An array is a special variable, which can hold more than one value at a time or you can say

An array stores multiple values in one single variable.

If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this:

 array() function is used to create an array

Example:- 

$cars = array("Volvo", "BMW", "Toyota");

In PHP, there are three types of arrays:

  • Indexed arrays - Arrays with a numeric index
  • Associative arrays - Arrays with named keys
  • Multidimensional arrays - Arrays containing one or more arrays


  • Indexed arrays - There are two ways to create indexed arrays:

    1) $cars = array("Volvo", "BMW", "Toyota");

    2) 
    $cars[0] = "Volvo";
    $cars[1] = "BMW";
    $cars[2] = "Toyota";
  • Associative arrays - Associative arrays are arrays that use named keys that you assign to them.

    There are two ways to create an associative array: 

    1) $age = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");

    2) $age['Peter'] = "35";
    $age['Ben'] = "37";
    $age['Joe'] = "43";


Multidimensional arrays:- 

A multidimensional array is an array containing one or more arrays.

$cars = array (
  array("Volvo",22,18),
  array("BMW",15,13),
  array("Saab",5,2),
  array("Land Rover",17,15)
);
