create a variable?

[drooh]

Is it possible to do something like this?

$file = "file2";
${$file}_er = "something";
OR
$.$file."_er" = "something";

I want to create $file2_er using the variable $file

How would i go about doing this?

It is certainly possible to do such a thing. It's called variable variables [php.net].

Try your first example and play around with it a bit until it works as you want.

I had already looked into variable variables but i did not see any indication that i could concatenate on to it?

$file = 'file2'; 
${"{$file}_er"} = 'something'; 
print $file2_er;

This seems to work too

${$file.'_er'} = "something";

[coopster]

Yes, that will work too. There are many ways to parse and concatenate strings [php.net].
