[SOLVED] Put a variable in another variable somehow?

[anolan13]

Hello,

 

For awhile now I've used code to get the size of a folders content (folder "files") on my server, this is the line that is now causing me trouble...

 

$total = total_size('files/');

 

But now I want that folder to be a variable instead so maybe the folder is named "files" or "dogs" or "oranges" or anything...so I picture the new line of code being something like this

 

$total = total_size('$files/');

 

Where $files is a variable, but it just wont work. I've tried everything, removing the ' 's ... the / I've played around with it for a long time and I get nothing.

 

So how do I make this work?

 

Any help is greatly appreciated,

 

Thanks!

try...

 

$total = total_size("$files/");

I'm not sure I understand what you're asking entirely, but you could try something like this:

 

$files = "files/";
$total = total_size($files);

 

Hope this helps.

I have found that some functions do not work with compound variables.......

 

solution give the function a simple variable

$files=$files."/";
$total = total_size('$files');

Variables surrounded by single quotes are not evaluated.

 

This should work:

<?php
$total = total_size($files . '/');
?>

 

If that doesn't work, please show use the code for the total_size function.
