I don't , I mean if the function is not str_replace you do not necesary need
the echo (array_push, as example)
This notation:
<?=
is deprecated since dunno how long ago ... strongly not suggested

How do you pass that string?
If you replace via other file, you do not need to use strings, just call the
function.
If you are parsing a variable, you do not need the inline ...
$_GET['function']("a", "b", "aaa");
if the query string is &function=str_replace
I do not get the problem at all specially now that you do not need variables
... and if you will end up with eval, you are doing something wrong.

Thanks Ashley...that did the trick.
After reading about the limitations of strip_tags I decided to just replace
the bad bits as below...
It still uses your "foreach" suggestion but replaces "<" and ">" with "("
and ")" instead of stripping tags.
I think I will extend the good and bad arrays to deal with magic quotes also
!
$bad = array('<','<','<', '>', '>', '>');
$good = array('(', '(', '(', ')', ')', ')');
foreach ($_POST as $key => $value) {
$_POST[$key] = str_ireplace($bad, $good, $value);
}
I'd do something like this, so as to preserve the original post data
array:
$data = Array();
foreach($_POST as $key => $value)
{
$data[$key] = strip_tags($value);
}
Note that strip_tags() will not be able to decently clean up messy code
(i.e. code where the opening or closing tags themselves aren't formed
properly)

Good Morning / Afternoon,
We run several of our own servers:
- Dell Power Edge 1U, Pentium,
- FreeBSD (6.x soon to be 7.x)
- along with all the standard Web Application installation (PHP Apache Exim,
Pop3, Proftp, MySQL etc etc).
What I am asking here, is if any one in this community has the knowledge to
act as a security consultant in an occasional, as required basis. Anyone
interested should have expience with Apache, PHP, Perl on the FreeBSD
platform.
We are more than willing to compensate for services rendered, and are more
than willing to discuss terms.
In the end, we would be more than willing to share any non-fudiciary
information with anyone who could find it useful (via this or other mailing
lists).
We are asking any interested parties to contact us off-list such that we
don't need to make any private matters public.
This is a bonified request, as we can setup servers ourselves, but simply do
not have the time to research various run time, and security related items.
TIA,
-Grant
