[SOLVED] Adding a string to the end of a varibale name.

[Splash]

Hello everyone.

 

I'm working on a project at the moment and have hit a bit of a brick wall, and am hoping you guys can help me with it. 

 

Basicaly I'm trying to create a new variable by adding a string onto the end of the variable name. i.e.

$Variable1 = 1;
$Variable2."$Variable1" = "Value"

$Variable1++;
$Variable2."$Variable1" = "Value"

Which would result in
$Variable21 = "Value"
$Variable22 = "Value"

 

Does anyone know how this can be achieved?

 

Thankyou

You can do this:

 

$n = 1;
$varname = 'Variable' . $n;
$$n = 'Value';
print $Variable1;

 

The "$$" is what allows it to work.  The other option is using eval(), but there's no need for that in this case.

Ah that looks good to me, I'll try it and let you know how I get on.

..OR

 

$ctr = 1;
$variable = $Variable2.$ctr; 
$variable = "Value";
print $variable;

$ctr = ++;
$variable = $Variable2.$ctr;
$variable = "Value";
print $variable;

Sorry, I'm tripping.. I meant to say

 

$$varname = 'Value';

Why not just use an array?

<?php
$var = array();

$var[] = 'first value';
$var[] = 'second value';
$var[] = 'third value';

echo $var[0];             // --> 'first value'

echo '<pre>', print_r($var, true), '</pre>';
// -->
// Array
// (
//    [0] => first value
//    [1] => second value
//    [2] => third value
// )


?>
