Associative Arrays

An associative array is a type of array where the key has its own value. In an associative array, we make use of key and value.

There are two ways to create an associative array: 

Example 1:

<?php
$age = array("Kailash"=>"27", "Ranjeet"=>"37", "Hemant"=>"43");
echo "Kailash is " . $age['Kailash'] . " years old.";
?>

Output:

Kailash is 27 years old.

Example 2:

<?php    
  $salary=array("Kailash"=>"350000","Ranjeet"=>"450000","Hemant"=>"200000");    

  echo "Kailash salary: ".$salary["Kailash"]."<br/>";  
  echo "Ranjeet salary: ".$salary["Ranjeet"]."<br/>";  
  echo "Hemant salary: ".$salary["Hemant"]."<br/>";  
?>   

Output:

Kailash salary: 350000
Ranjeet salary: 450000
Hemant salary: 200000
