function help

i'm having trouble getting my function to return back variables to the page that called it.

 

in the function i have variables $student1, $student2 $student3 in a function called getstudent.

 

the code below on page student.php calls the function, if i return $student3 on page student.php if i echo $student3 it is blank. 

 

 

any ideas?.. i don't want to echo it within the function.

 

$thedatabase = new Database();
$thedatabase->opendb();

$input = $thedatabase->getstudent($student);

return $student3;

Your capturing the returned value into $input not $student3.

It's really difficult trying to interpret it with that little bit of code, no specifics on the function or anything...could you try and specify?

EDIT: thorpe didn't seem to have any issues with it.  

 

What you're saying is about right, you don't want to ever echo from the function when you can return. However if something returns a value, you need to echo it where ever you are calling it.
