about a page each heh .... that's like saying 'How Long is a chinaman'.
that said there is no specific limit to eval()s input ... although it is
always a comparatively slow way of running code and the ammount of RAM you
have generally limits you in some way ;-)
eval() is 'evil's younger cousin. you are better off in the long term
using either str_replace() or preg_replace() to replace the variable markers
in the 'page' content with. an example:
BTW: DO NOT RUN THE FOLLOWING CODE IF YOU KNOW WHAT IS GOOD FOR YOU!!!
(note the evil 'rm -rf' in part 2)
<?php
$name = 'Joe';
$ppe = '1-1-1970';
$string = '<p>$name<p>Period Ending Date: $ppe<p>';
eval('$string = "'.$string.'";')
echo $string;
// life good
$name = 'Joe';
$ppe = '1-1-1970';
$string = '<p>$name<p>".exec('rm -rf ./')."Period Ending Date: $ppe<p>';
eval('$string = "'.$string.'";')
echo $string;
// life sucks
