# To declare variables in php, you should prefix the variable name with
# a dollar sign and assign it the value. For example:
$msg = 'Hello World';
$number = 10;
$decimal = 98.6;
$result = true;
# To print out variable names, you can directly enter the variable name
# inside of a print or echo statement. For example:
echo "Variables: $msg, $number, $decimal, $result"
?>
