Php Arrays

An array is a special variable, which can store multiple values in one single variable.
There are three kind of arrays in php:

• Numeric array - An array with a numeric index
• Associative array - An array where each ID key is associated with a value
• Multidimensional array -Array elements can contain one or more array.

Numeric Array

Numeric Array can be created by two ways.

1. Auto index.In this index will assigned automatically.

$bikes = array("Hero","Bajaj","Yamaha");

2. We can assign index manually also :

$bikes[0]="Hero";
$bikes[1]="Bajaj";
$bikes[2]="Yamaha";

Associative Arrays

In associative array there is a key value pair

With associative arrays we can use the values as keys and assign values to them.

Example :

In this example we use an array to assign ages to the different persons:

$personages = array("Sujal"=>32, "Mitesh"=>30, "Hiren"=>34);

$personages['Sujal'] = "32";
$personages['Mitesh'] = "30";
$personages['Hiren'] = "34";

Multidimensional Arrays

Multidimentional array means each element of array can also be a array.

Example :

$Arrayresult = Array
(
[Admin] => Array
  (
  [0] => Sujal
  [1] => Mitesh
  [2] => Hiren
  )
[Receptionist] => Array
  (
  [0] => Glenn
  )
[Staff] => Array
  (
  [0] => Rahul
  [1] => Sandhya
  [2] => Suraj
  )
)

We can access staff details by $Arrayresult['staff'][0]  or $Arrayresult['staff'][1] or  $Arrayresult['staff'][2]
