PHP Create Associative Arrays

In this chapter you will learn:

1. What is a PHP Associative Array
2. Syntax to create PHP Associative Array
3. Example of a PHP Associative Array
4. Example - Create Associative Array with different type of values

Definition

PHP Associative Arrays are array with your own keys.

Syntax

We can use array() function to create associative array.

$myarray = array("key1"=>"value1", "key2"=>"value2", ....); 

Example

The following code creates a PHP associative array to hold the key value pair.

<?PHP
$myarray = array("a"=>"Apple", "b"=>"Bag", "c"=>"Cat"); 
var_dump($myarray); 
?>

The code above generates the following result.

PHP converts floating-point numbers to integers in the associative arrays, which essentially rounds them down.

Example 2

The following PHP code creates an Associative Array with different type of values.

<?PHP//  j av a 2s .  co m
$myBook = array( "title" =>  "Learn PHP from java2s.com", 
                 "author" =>  "java2s.com", 
                 "pubYear" =>  2000 );   

?>

This creates an array with three elements:

• "Learn PHP from java2s.com" , which has an index of "title";
• "java2s.com", which has an index of "author";
• and 2000 , which has an index of "pubYear".
