Do the get sizes while it is still as a file after upload then save the size
info with the file in the db or use unpack to get the size from the raw data, it
is usually in the header somewhere.

Yes, but exec() itself does NOT output anything.

Dear All,
I write a php scripts to use the function of fsocketopen to gather some
data on the web, everything is perfect when I test the scripts on the apache
server installed in my pc. But when I upload the codes to the server I
hosted, I always got a time out error, even after I enlarge the time out
setting to 180 secs. Could you tell me why it happen and how to figure it
out?
Thanks,

Check whether the firewall is blocking whatever it is you're trying to access.

You can do it manually:
http://shiflett.org/hacks/php/http_post
Other options are cURL and various PEAR classes.
Hope that helps.

Are you trying to go to a section of code to perform some operations on
current variables? If so use functions
http://us3.php.net/manual/en/ref.funchand.php . If you have some sort of
decisive mechanism use switch http://us2.php.net/switch

Greetings,
I'm working on a project that involves a password protected area of a
website. Some one also involved brought up the point that this area should
be secure (Whit the lock icon indicating it is encrypted).
In this particular project the password protected area will be a quote
generating system for a company. Users would log in and choose the products
they are interested in purchasing and the site would generate a quote
depending on what they selected from the list of products.
So my question is..
At what point is encryption necessary? I've always thought encryption was
only needed when dealing with stuff like credit card information, am I
wrong?
if you are sending passwords over the internet, then they can be sniffed
in transit, it depends on how paranoid / how important the information
is. Unless you encrypt them before sending (client side), but this is
quite complicated
You probably should just use https to do the encryption, it works the
same as normal, the HTTP layer deals with all the encryption for you
How secure is a password protected page done with just PHP?
over http, with no encryption - not very secure
over https - as secure as anything is on the internet
Thanks
Chris

Greetings all, I ran into a problem today and was
hoping someone could provide an answer.
I am fetching a web page, and attempting to parse
certain variables from it. I've done this plenty of
times in the past with no problem. The only
difference this time is the file that I am parsing is
much larger. The HTML file is about 42kb in size
(usually I only parse ~4kb worth). In the web
browser, the script seems to just shut down, but
reports no errors, not even to the web server logs.
Is there some specific max size that it can accept or
a setting in php.ini I need to modify?
Thanks
hi,
i don't think, that 42k is too much for the size of your file. mut maybe
php simply times out while parsing? there is a php.ini-parameter
max_execution_time and a runtime-function set_time_limit(). try
set_time_limit(0) at top of your script fo debugging.
also take a look at preg_* functions instead of ereg_*. they are said to
be much faster.
