Easy Php variable question

[Evanthes]

Hey guys I got a variable ($ncorr) that I'm using to count the numnber of correct answer for a test...everything works fine, except when i want to call the variable outside of the for statement check out my example

[code=php:0]

if ($ncorr == '10') {
$mess = "you got ten right";
echo "<font size='1' face='verdana'><center><h1>$ncorr/8!</h1><br/>";
echo "$mess</center></font>";
}
echo "$ncorr answers<br>"; //variable shows up here
}
echo "$ncorr questions answered correctly"; //variable doesnt here

[/code]

Any help would be greatly appreciated!
thanks!

Can you post the rest of the code? The code snippet you posted doesn't have enough information for us to give a meaningful answer.

Please post the code between [nobbc][code][/code][/nobbc] tags.

change
[code]
echo "$ncorr questions answered correctly";
[/code]
to
[code]
echo "{$ncorr} questions answered correctly";[/code]

You got an extra bracket on line 5 or 7. when you want to divide. instead of $ncorr/8, use ".($ncorr/8)."

The $ncorr variable is added via a if statement, then another if statement calculates the number of questions that were correct. the problem is that the variable doesnt hold its value outside of the if statements, as I want to use it in an email function. thanks a lot guys.

fert- didn't work
GFD- I'm not trying to divide, just showing the user the number they got right out of the total number of questions.
thanks for the help guys

The structure of this code is horrible and impossible to follow.

I notice that you are defining $ncorr in a function. If you are trying to use the value outside the function it won't work. This might be your problem.

hehe yeah I'm def not that great at coding...

yeah I'll try defining it outside and see where that gets me
thanks

[kenrbnsn]

If you define it outside the function and want to modify it in the function, you need to use the global statement within the function. A better solution would be to return the value.

[Evanthes]

how could i go about returning the value? Ii's working a bit better by defining it outside the function, my functions still work, and outside the functions I am getting 0 for a value instead of nothing like i had before.

[emehrkay]

$val = function();
just make sure function() returns the val you want to return, then you can use $val all over the place
