You mean like this ?
<?
$file string = file_get_contents(urlencode($file_path)); <http://us3.php.net/manual/en/function.file-get-contents.php>

$result = eval($file_string);

?>

Well I see a few problems with this. One is that scope is not lexical. In other words if $foo exists somewhere in the script and $foo also exists in $file_string then $foo will retain the value it was set to in $file_string. That could lead to some debugging hell. Also, you would have to collect the output and manually return it which means you would have to keep an output cache which means you could only use scripts that cached output and returned them explicitly. However, the flip side is you could have a buffer declared in the local scope that collects the output of $file_string and then put that in the message, but that is not the same as:

$foo = include $bar; # this is, of course, impossible

Can't you just use the eval <http://nl2.php.net/eval> function, and parse the code from the include file in it?

.. or is there something I'm missing here?

                    Also I am not sure but did you try retrieving
                    content with fopen() ?

                    Something like

                    $file = 'invoicetable_bottom.php';
                    fopen("http://yoursite.com/folder/$file","r";);

                    http://tr.php.net/function.fopen

                    worth trying. Easier than output buffering

                This would not work.  fopen would open the file for
                read.  What you would be
                reading is the actual source of the document.  Not the
                data the script would
                output when ran.

                The ob_* functions are the only way that I know of to
                do what you are asking

                    Hi,

                    The simplest way (actually the single way I know
                    :) ) would be to
                    capture the output using output buffering
                    functions, something like this:

                    // start output buffering
                    ob_start();

                    // include the file that generates the HTML (or
                    whatever content)
                    include "....";

                    // get output buffer content
                    $output=ob_get_contents();

                    // clean output buffer and stop buffering
                    ob_end_clean();

                    // the content generated in the included file is
                    now in $output variable
                    // use it as you consider fit
                    .........


                    Regards,
                    Puiu

                        I have an invoice table that is drawn on a

                        all the logic in an include-file like this:

                        include "invoicetable_bottom.php";


                        However, now I'm needing to take the output
                        from that include file and
                        pass it as an email.  To do that, I need to
                        somehow take the output from
                        this include file and get it into a variable
                        somehow.  Is there a simple
                        way to do this?

                        Something like:  $emailtcontent = include
                        "invoicetable_bottom.php"?

            That's just crazy talk. If you use fopen on a web URL,
            then it will
            always return the output the script generates. That's how
            http works!


        Sorry, my bad.  Ash is correct, the method that is suggested
        will work.  But you
        will need to enable options in your php.ini that are not on by
        default for
        security reasons, plus as Ben points out, you will need to
        filter out the scruff
        that is generated to capture just the data output from your
        include.

        Mind you that all of this also requires that the file that you
        are including is
        accessible via the web.  It could be in a folder that is not
        web accessible.

        Sorry for the initial confusion!

            Thanks,

    Do you have php configured to compile files? Why not just backtick
    the php -f command??

    <?

    $cmd = *escapeshellcmd*("/full/path/to/php -f $file");
    $email_output = `$cmd`;

    # do something with $email_output

    ?>

    Seems easier than a whole http call.. can be risky if the $file
    variable can be set by user input (big no no), but other than
    that.. seeems the simplest.
