Question

I don’t understand this code:

$outputFunction($dst, $resized, $quality);

It’s not a function e.g myfunction()

It’s not a variable e.g $variable = $variable2

What is it?

The code works in the script i have downloaded, i just can’t figure out how that piece of code can work…maybe i’m just tired or something..

Thanks.

Answer 1

$outputFunction holds the name of the function. Thus, if $outputFunction holds the value "calculate", then calculate($dst, $resized, $quality) is invoked.
