Array In PHP

Array In PHP

PHP supports three types of arrays :

1. Indexed arrays
2. Associative arrays
3. Multidimensional arrays

Index Arrays :

An indexed array stores values in sequential numeric indices, start from 0 . you can create an indexed array using the array() function or the [] shorthand syntax.

$country = array("India","USA","UK","UAE");

You can access the elements of an indexed array using their index :

echo $country[0];  // output “India”

echo $country[1];  // output “USA”

Associative Arrays:

An associative array stores values in Key-value pairs, where each key is a unique string identifier. you can create a n associative array using the array() function or the [] shorthand syntax.

$people=["name"=>"Manan","age"=>"25","mobile"=>"9878357855","email"=>"abc@domain.com"];

You can access the elements of an associative array using their key :

echo $people["name"];  // outputs is “Manan”

Multidimensional Arrays

A multidimensional array is an array of arrays, where each element can be an indexed or associative array. You can create a multidimensional array using nested array.

$men = [ 

["name"=>"Pawan", “age”=>20],

["name"=>"Manan", “age”=>30],

["name"=>"Kuldeep", “age”=>40] 

];

you can access the elements of a multidimensional array using multiple indices:

echo $men[0]["name"];  // output is Pawan
