Question

please give me any simple example to understand properly.

thanks in advance

Answer 1

i think you didn't get me. "variable variables" is one of the topic of php which switches its value with another variable (according to me its for no reason). it means suppose there are two boys (Joe and Josh) and if you call Joe then Josh will respond. what is the use of this functionality in real time?

Answer 2

oder foreach (); that need php used

Answer 3

<?php
$test1 = array("age"=>"18", "color"=>"blue");

$test2 = array("age", "color") ;
echo $test2 [1].": ";
echo $test1["color"]."</br>";
// OUTPUT color: blue
?>
