  • displaying a variable and then setting it

    I know that in PHP4 there's an option where you can display a variable, and then later set it to what you need it to be like I have a single php page that will show the user diffrent information based on the user input, and in the header file, I put this code:

    <?
    print "&$headtitle";
    ?>

    and later on within my if statements i would put
    $headtitle="Option 1 selected";

    and by what my book tells me, "Option 1 selected" should show up in the title bar, but it doesn't, all I get is an & in the title bar

    thanks,

    Using the ampersand passes a variable by reference to another variable, meaning whichever happens to the referenced variable happens the to variable being referenced.

    A variable cannot be used before it is defined.
