Php Tutorial 5 + 6

Tutorial 5

echo (" The variable \$applicant equals $applicant.")

the 1st $applicant has a \ behind it so it actually prints $applicant instead of the egality of $applicant

echo (" The variable \n$applicant equals $applicant.")

after the \n there is a new line.

Tutorial 6

$field = "ProductID" ;
$$field = "432BB" ;

echo ($ProductID) ; // Prints 432BB
echo ($$field) ; // Prints 432BB

these are called variable variables
