[PHP] When are Form Variables Null?
Hi,
I've been wondering the behavior of browsers and POST submissions..
basically I'd like to know the behavior of:
is_null(), empty(), and isset().
I've found that sometimes when an item is not filled out, the variable
is still set on the subsequent page, like $_POST['var'] = "";
What does everyone use to see if forms were submitted correctly?
I built my own function:
function form_exists($variable)
{
if (strlen($variable) < 1)
{
return false;
} else {
return true;
}
}
It was the only apparent way I could know *for sure* that independent of
the browser, I knew what the heck was being submitted.
Thoughts?
Thanks,
Al

Re: [PHP] Run two separate version of Apache and Php
I believe you will need to compile two versions, and point two to different php.ini locations. Here's a snipet from the manual. http://www.php.net/manual/en/install.configure.php#install.configure.options.php Al --enable-maintainer-mode Enable make rules and dependencies not useful (and sometimes confusing) to the casual installer. --with-config-file-path=PATH Sets the path in which to look for php.ini, defaults to PREFIX/lib. --enable-safe-mode Enable safe mode by default. --with-exec-dir[=DIR] Only allow executables in DIR when in safe mode defaults to /usr/local/php/bin. --enable-magic-quotes Enable magic quotes by default. --disable-short-tags Disable the short-form Hello php-general, > > I need to run a separate version of Apache on the same server I also > what to use a different copy of the php.ini file with that version of > apache.

Re: [PHP] Session Events
Well, since HTTP is stateless you can really say that this event happens in either of two places: - The next page accessed by the user with that session ID - As an event in the backend. If it's the first, I would recommend just having a lib_session that verifies a timer or whatever and then redirects the page or whatever. If it's something in the back-end, like a user accesses a page and you need to do clean up 30 minutes after that user goes inactive, then I recommend that is done in like a database stored procedure.

Re: [PHP] Need Help with $_SESSION.
You must do a session_start() before you can use the session ID or the
session array.

Re: [PHP] PHP and Apache
I had a problem where I compiled in too many extensions and apache thought the module file was too complicated, and thus corrupt and wouldn't start.

Re: [PHP] Re: Development Tools
I've picked up PHPed, Zend IDE, and Dreamweaver MX. - ZendIDE has the best code-completion and editing features out of all of them, best auto-tabs and auto completes. - PHPed is ok, better with database and total MySQL development then Zend IDE. - Dreamweaver MX has limited PHP support but it is far superior on the front end than the other two. If only there were a ZendEd MX, hah.
