Hay - -- (oats)
Playing some more with PHP. Boxed myself into a corner where I need
to do a macro substitution-type of capability. For example, I have
bunches of variables like this:
...
$Q02_buzz
$Q02_fuzz
$Q02_suzz
$Q03_buzz
$Q03_fuzz
$Q03_suzz
...
I need to tease out the value of Q08_fuzz, knowing the naming
convention and that I am at "08." In Fox, one could:
Stringly = "$Q"+padl(8,2,"0")+"_fuzz"
? &Stringly or
? (Stringly) or
? eval(Stringly) depending on the situation.
I need to do the same thing in PHP. The PHP eval() function seems
like the right one from the description, but I can't get it to work
without an error (parse error, unexpected $end ... It seems to want
to eval() a whole script.)
Anybody know if there is an equivelant?
(BTW: I am just making up the example, so please don't take the
variable design seriously and suggest starting from an array or
something.)
I'd ask a PHP group, but I don't know if anybody else would
understand a "macro substitution."
