Subject: [PHP] dynamic variables in a while loop?
Hi everyone.
I am more of an ActionScript person, but I have to do this one in php.
Should
be easy for everyone familiar with php syntax...
Here is what I want to do:
I am getting several variables into a Php Script such as:
help1 = "yes" / "no"
help2 = "yes" / "no"
.
.
.
helpX = "yes" / "no"
I need to check whether the variable is true or false, and according to that
add
1 to a counter variable.
Something like this I'd do in ActionScript, but dont know about php
[CODE]
$i = 0;
While (++$i <= 8) {
if ([help]+$i=="yes"){ // this line produces an error...
$counterYes += counterYes;
}
}
[/CODE]
Do I have to initialize all variables before I can use them in php?
Thank you very, very much for your time and your help!!
Philipp
