help with variables and arrays

[Anon]

Hi,

does anyone know how i can make something like this work.

$Garbage1 = "foobar";
$blah = "Garbage" . $count;
print ($$blah);

This returns 'whackness' which makes perfect sense, but if i try to use this
method with an array it never treats the $$blah as a variable, instead it just
outputs the combined string.

$tester = "TypeQ" . $count . "[" . $count2 . "]";
print ($$tester);

This outputs ' $TypeQ1[1] ' which makes sense but i have an array named
' $TypeQ1[1] ' with a value in it and i don't know why it doesn't
take the value from the array as it does in the previous example. $count and
$count2 are just integers in a loop that keep increasing..

any input will be appreciated.
Thanks!

I don't think you can reference array values like that. You can do one of two things:

$my_array1 = array ("foo", "bar", "baz");
$count = 1;
$count2 = 1;

$ref = "my_array" . $count;

// either this
print (${$ref}[$count2]);

// or this
eval ("print (\$${ref}[$count2]);");

// should print bar

Thanks a lot Eden, I really appreciate your help.

another solution is to make another dimenstion to the array:

$my_array[1] = ["foo", "bar", baz");
$count = 1;
$count = 2;

print($my_array[$count][$count2]]);

and both this and the previous example (from eden li will print foo and not bar as eden said)
