    How can I include "place holders" for variables in a heredoc such that after the heredoc is declared, I can assign the
    variables?
    I have a config file with a heredoc string declared. I'd like to keep the include config.inc at the top of my page.
    Down in the page, when I call the heredoc variable, I'd like to replace the "place holders" with a values assigned in
    the page, below the include statement.
    I know I can break up the heredoc into several segments and put the variables between them; but, I rather not.
    Seems like there should be an obvious way to do this.
    Thanks

    Al,

    Escape the $'s in your heredoc expression so that the variable names
    remain and aren't evaluated, then eval() the whole expression later:

    $sString = <<< hdBodyClass
    <body class="\$sBodyClass">
    hdBodyClass;

    This sets $sString equal to:

    <body class="$sBodyClass">

    Then:
    $sBodyClass = "contact";
    eval("\$sHTML = '$sString';");

    Evaluates as:

    $sHTML = '<body class="contact">';

    As always, be careful not to include any external data in an eval()
    statement without careful sponging. Its presence in your script
    should be regarded as an Achilles heel and treated with special respect.

    str_replace() ?

    Yes, that is the simplest solution. Now that you've refreshed my memory, I've done it that way in the past.
