can you go to jail for doxing code example

Example 1: How can you print in lua/roblox

-- You can print string
print("Hello, World!")
-- You can print math
print(5 + 5)
-- You can print variables
local i = 5
print(i + 2)
-- You can print number
print(5)

Example 2: when should I use a DIRECTORY_SEPARATOR vs a slash

It doesn't matter -- PHP's IO functions will internally convert 
slashes to the appropriate character.
