I am passing a string and making sure all the characters in that string
are valid.
Example:
For a persons age I am using:
if (!preg_match(/^[0-9]+$/, $Age)) echo Enter numeric value for age.
But how would I include the following characters as permissible in preg
match
Anyway to reverse the effect of htmlspecialchars?
Reason: to send an email message where quot; is shown as and not
quot; LOL
Thanks.

between pages is when i included the ?=SID? in the URL's (AND THIS

BUT, If I remove that PHP sniplet, the session restarts on

Hey all,
I am using the Zhang session method from
http://www.phpbuilder.com/columns/ying2602.php3 and it works great
with a mysql database.
Does anyone out there know how to tell if a session is expired using
this method? The Read Session function is:
$Str = apple,orange,cyanide,bananna
$Arr = split(,,$Str);
How do I remove the unwanted value from the array?
(in this example, Cyanide ($Arr[2]) from the Fruit array)???
Thanks.
array_splice()???

When I hit the back button on Page 2 it tells me it has to requery the

Is there anyway to make it use the cached copy instead of
Yes, I would prefer using the back button and go to the page in the clients
cache but I think you are right, I may have place a back button on the page
that actually resubmits the query paramemters for me.
Finally found something that ASP pages can do better than PHP... but only one
thing. :)
Doing some research I found that session cache paramemters may be set in
PHP.INI or overridden by inserting the following header() lines into the
php for the page you want to cache on the clients browser.
Allow Cache Expire time is set in php.ini in minutes. Search php.ini for
key word cache
Also consider:
header(Cache-Control: public);
header(Cache-Control: max-age= . $this-allowcache_expire * 60);
This will allow to set the expiration of the cached file on the on the clients
browser. The Cache Expire time is in minutes and can be found (and changed)
in the php.ini file. Search
The manual shows that you can use switches with numeric values but is it
also possible to use strings? Is this possible? If not, what can I

echo $ImgData;

it appears the data error problem occurs before it reaches this script. Maybe
