    I thought I'd provide some extra information just so you understand.

    In your code:

    $raceramps56["short"] = "My Test Product";
    
    $leftMenu = 
    
    '<div class="leftMenuProductButton"><?PHP echo $raceramps56["short"] ?></div>';
    

    You are including literally.

    Take a read of this. http://php.net/manual/en/language.types.string.php

    When I was first learning, I did not understand the different between literal ' and double quotes and it especially caused problems when I was trying to echo things.

    Take a look at this:

    <?php
    echo 'this is a simple string';
    
    echo 'You can also have embedded newlines in 
    strings this way as it is
    okay to do';
    
    // Outputs: Arnold once said: "I'll be back"
    echo 'Arnold once said: "I\'ll be back"';
    
    // Outputs: You deleted C:\*.*?
    echo 'You deleted C:\\*.*?';
    
    // Outputs: You deleted C:\*.*?
    echo 'You deleted C:\*.*?';
    
    // Outputs: This will not expand: \n a newline
    echo 'This will not expand: \n a newline';
    
    // Outputs: Variables do not $expand $either
    echo 'Variables do not $expand $either';
    ?>
    

    If you were to use " " instead of ' you would not get the same output because " will interpret everything rather then take it literally.

    I hope this has been of additional help, even though you have had your question answered already.

    You can run php in a '. You can only echo it like this if you know what I mean.

    $leftMenu ='<div class="leftMenuProductButton">.$raceramps56["short"].</div>';
    echo $leftMenu;
    

    Use this:

    $leftMenu ='<div class="leftMenuProductButton">'.$raceramps56["short"].'</div>';

    Or without the need of escaping double quotes:

    $leftMenu = '<div class="leftMenuProductButton">' . $raceramps56["short"] . '</div>';

    try this

    $raceramps56["short"] = "My Test Product";

    $leftMenu ='<div class="leftMenuProductButton">'.$raceramps56["short"].'</div>';
