I was going over my review for my HTML exam.. and have a couple questions I could not answer or find the answers to....
1) What is the scope of a constant?
a. visible in the script but not in a function
b. Once declared visible globally
c. Only visible within functions
d. Only visible in the script
I think the answer is D , but im not too sure..
2) What is whitespace used for in a program?
3) $a = 4;
echo $a--;
echo $a;
what is the value of $a that is echoed in the echo?
Is it 8?
What is the function to delete a file?
Is it delete()?
