What are different types of arrays in php?

Example -

In php there are 3 types of arrays.

1.      Index arrays

2.      Associative arrays

3.      Multi-dimensional Arrays.

Code and Syntax –

//Index arrays

$emp=array("e1","ba","cd");

$alength=count($emp);  // find the length of emp array.

//Associative arrays

$sal=array("sagar"=>"35000","amol"=>"390907","Jockey"=>"43000");

//$sal['ganesh']="398985";

//To iterate the associative array use below code

<?php
foreach($sal as $key=>$val)
  {
  echo "Key=" . $key . ", Value=" . $val;
  echo "<br>";
  }
?>

Explanation –

In above examples, we have created indexed arrays and associative arrays. Difference between 2 arrays is that in index arrays we store the values based upon numerical index. While in associative array, we store the values based upon key.
