Variable Concatenation

[Anon]

This is racking my brain, and maybe this is stupid but I need this to work...
$test1 = 35;
$test2 = 20;
$i = 1
$k = 2
echo($test$i); //Output 35
echo($test$k); //Output 20
Of course that is bad syntax, but is there a way to do the same thing? This is my situation, I have three array coming labeled name3[], name9[], name11[], etc, where the number represent a unique id. and these arrays are filled with data from a form on a previous page. I need a way to get to name3 and name9 etc, dynamically, I will know which unique ids and the fact that it is namexx[]. but I need to combine./

Easy, you were almost there.

Correct syntax for doing this:
echo ${'test'.$i};
OR
echo ${"test$i"};

See Variable Variables in the manual, under Variables section.

Cool, I tried lots of different stuff, even read some stuff on v-vs, but didn't come up with it. Thanks a lot.
