    PHP Tutorial 2 - Variables

    This is a follow-up to my previous tutorial: PHP Tutorial 1 - Printing. It's wise you should read the last tutorial before you come onto the next one.

    Variables, like in all programming languages, is a value that can change constantly. Variables in PHP can be used everywhere and are very easy to define, for e.g.

    PHP Code:
    "Connor Simpson"
    echo $variable;

    Connor Simpson
    Variables can either be string(which is text) or integer(which is a numeric value). Text must be wrapped around quotation marks and numbers don't really have to, it helps that they're not.

    PHP Code:
    "This is a piece of text!<br />"
    $number 13;

    This is a piece of text!
    Variables can also be a boolean value (which means true or false). Boolean values, to take effect, must NOT be wrapped around quotation marks:

    PHP Code:
    $thisisfalse false;
    Booleans can't be printed like normal variables since it's really just a pointer for PHP.

    Variables are key in PHP and most scripts you'll be making will use variables in some form. Thanks for reading.
