I was hoping to avoid concatenation to make my code more legible (less illegible?).
I take it then that there is no equivalent for the use of ` in Unix.

You need to use the string concantenation operator (a period) to use things
like $test++, else PHP get's confused.
> echo "Value of test: $test++ <BR>";
To get that to work like you want it to, you need only do:
echo 'Value of test: ' . $test++ . ' <BR>';
It's functionally the same, no brackets needed. If you want it to be
evaluated BEFORE it's echoed, you need to use:
echo 'Value of test: ' . ++$test . ' <BR>';
