its says

PHP Code:

$code = red_code($var); Don't code like this
$code = normal_code($var); Code like this 


and im asking wtf is the diffreance between 2 lines ? (excecpt the function name)

[Xenon]

actually it's an example, red lines mean not to code like that, and normal colored lines mean ok.

the difference between the two lines was just the color, both lines itself are valid of course
