array with updatable variables

[nunomira]

I'd like to do something like:

$a = 1;
$b = 3;
$c = 5;

$array = array ($a, $b, $c);

// change the value of the variables in the array:
$array[1] = 25;
// in order to have $b = 25...
// this just changes the second element of the array, not the variable

[nunomira]

this is a way...

<?php
$a = 1;
$b = 3;
$c = 5;

$array = array ("a", "b", "c");

${$array[1]} = 25;

echo $b; // 25 as wanted
?>

is there any other?

Your not being very clear about what you want.

$a = 1;
$b = 2;
$c = 3;
$array = array(&$a, &$b, &$c); // Pass values by reference

$array[1] = 25; //Both array value and original variable are changed

echo $b;

even considering that I haven't been very clear, you've provided a great answer!

that's what I was thinking of... passing values by reference, but wasn't able to get there.

thanks!

I think the big question is why you want code to do that 😉
