note 102698 added to function.eval

I have looked for a simple way of forcing PHP to interpolate strings after the event (that is, after they have already been assigned, say from a text file).

The following seems to work:

<?php
	$text='$a + $b = $c';
	$a=2; $b=3; $c=$a+$b;
	print eval("return<<<END\n$text\nEND;\n");
?>

I have even tried it with some potentially evil code, but the context seems to preclude interpreting it as anything other than a string.
