how to append data to variable name

[felix822]

Hello everyone. I have a few variables named in this format - $NameX1 and $NameY1 and so on. They're XY coordinates. I also have a counter variables - $XCounter and $YCounter which will increment in a 'foreach' loop.

 

I'm trying to append the $XCounter to $NameX so in my loop I could call $NameX1, $NameX2, etc. I tried $NameX.$XCounter, but that didn't work. Any help would be appreciated.

first...you should be using Arrays for this. it would be MUCH easier

 

but to answer your question:

echo ${'NameX'.$XCounter};

That worked, thank you for the quick reply!

 

I'll try it with arrays instead. Thanks again.

Accessing an array variable is 3 times faster than using variable variables. If you have a lot of data, the extra time taken by the current method will add up.

I just re-wrote it using arrays and it is much simpler and data is much easier to access. Thanks.
