This is already possible in php, though with the following simple
// function to read a file with php-vars in as a string
// $predefined_vars: an array ("varname" => "value"). all the
// variablenames defined in this array can be used in the bodyfile.
// They will receive the respective values. This makes personalising
// the mailes easier..
function file_as_body($filename, $predefined_vars)
$ar = file($filename);
foreach ($ar as $number => $line)
eval("\$ar2 = \"$line\";");
and for instance this file as template:
<--- template file
You received a file on (" . date("d/m/Y (H:i)") . ")
filename: ".basename($file) ."
filesize: ".filesize($file) ."
Hope you enjoy it..
You can even use php-code already, thanks to eval :)
Maybe we better make it a PEAR-thing?

I've got these opium queens that move around my space,
I said it's waste not, want not,
I think I'll take another,
I'm holding all this pain that I'm trying to smother.
