PHP: Using variable variables.

Markus

Using the code below you can turn array indices into variables that can be accessed as a normal variable would be.

Expand|Select|Wrap|Line Numbers

 
<?php

/**

* @title    PHP: Variable variables.

**/
 
$array = array("Name" => "Foo", "Age" => 21);
 
foreach( $array AS $Key => $Val )

{

    $var   = $Key;

    $$var  = $Val;

}
 
// the array can now be accessed

// by using:

//

// echo $array_key;
 
echo "Name: $Name - Age: $Age";

// prints Name: Foo - Age: 21

?>

Just found out you can use the extract() function instead.

My work is pointless!
