Hi everybody,
Newbie is trying to set up OOP With PHP and MySQL or MySQLi database class
(using CRUD)
Simple story: creating this class database by myself is way over my head. So it
be best for me to find something on the Internet that has already been created
and working to pro specs (using CRUD with good security etc).
In my studying, it seems that there is a difference between MySQL and MySQLi -
MySQLi being the preferred choice if I understand correctly.
There are lots of examples on the Internet however I don't know enough about it
to know a good starting example from a bad starting example, so I would much
appreciate any assistance pointing me towards a good starting point
This seems a good start to me untrained eye, but it seems to be for mysql - not
mysqli...

The DreamInCode one is good. MySQLi is the recommended option over
MySQL since the mysql one is deprecated. PDO is also a great option
since you can prepare your queries to help sanitize the data

Aside from all the warnings and potential logic bombs?
You will have a negligible performance hit with all the isset() checks you'll
be using, but they won't be noticeable, and its preferred to use them than not
to avoid issues with missing values.

There might be a little performance hit because the error is getting logged
in your webservers logs, though if it is noticeable depends on which
webserver you're using, and how often there are undefined variables.

And frameworks like Drupal might intercept the error and store it in the
watchdog file. Then the performance will be degraded.

Sorry for the top post!
I don't know numbers, but my gut instinct is that the cycles wasted raising the
notice (it gets raised even if it goes nowhere so turning display and log
doesn't remove the hit completely) are better spent executing defensive code.
There is no reason, ever, that production code should raise notices about which
you don't care. If PHP is telling you something might be wrong, something might
be wrong! And if you're investigating the code already, figure out what's
happening and deal with it properly.
Only lazy and/or developers ignore notices. If you're one of them and this
statement offends you, you probably know it's right!

I agree with Stuart.
To minimize the overhead of testing every possible undefined variable with
isset(), I assign them at the top of the page which uses them. e.g.,
$userInstrHtmlSizeWarning = false;
$currentUserRecArray = array();
if(!isset($_SESSION['pwPassed']))$_SESSION['pwPassed'] = false;
I also have this snippet at the top of my app config file.
if(true){ // TRUE for debug only
ini_set("display_errors", "on"); //use off if users will see them
error_reporting(E_ALL)
$error_reporting = '<span style="color:red">Error display and logging
on</span> ';
}
else $error_reporting=null;
I put this at a convenient place on the page so I don't forget to turn off the
error reporting when the code goes live.
if($error_reporting) echo $error_reporting;

I've used the following method for accessing elements of the global arrays for
a long time. It saves a lot of typing!
http://stut.net/2011/04/12/php-snippet-array-element-access/
Note that if you're using PHP5 you should remove the & before the $a in the
function definition.

Hi list,
I am having trouble with error messages saying
"Using an empty Initialization Vector (iv) is potentially insecure and not
recommended"
These messages turn up using horde which uses ecb. I don't know the inner
workings of php and openssl but if I understand correctly, there is no IV used
in ecb hence there should be no error message according to this:
http://svn.php.net/viewvc?view=revision&revision=304179
(I am running php version 5.3.20)
Does anybody have any idea why I am getting these errors ? I can reproduce them
using this code:
<?php
openssl_encrypt ("Hallo","bf-ecb","abcdef");
?>
Regards
Stephan
Because E_WARNING is issued if the optional fourth parameter, Initialization
Vector, is NULL.
Is that so ? In ext/openssl/openssl.c it looks like php is questioning
openssl if the cipher in question needs an iv by calling
EVP_CIPHER_iv_length which according to its manpage returns 0 if the
cipher does not use an iv. If I understand correctly the warning only
gets thrown if the vector is needed and empty. Since ecb does not need
an iv this warning should not appear at all, should it ? This is also
how I understand the log for the code change:
http://svn.php.net/viewvc?view=revision&revision=304179
How exactly are the error messages troubling you? If they're appearing on
your site/pages, you should adjust server or site configuration.
That is what I did as a workaround but the question remains why I keep
getting the warning with recent versions of php. It doesn't matter if I
compile php against the 0.9.8 or the 1.0.1 versions of openssl.
Thanks

Hi all --
I've got a cloud server on Rackspace. If I bring up a fresh Ubuntu
12.10 machine image, and type "apt-get install php5" it seems to
install fine. But if I then type "php -version" I get "PHP Parse
error: syntax error, unexpected end of file in Command line code on
line 1".
What went wrong? How can I fix it?

Not only is that extremely vague, but it's possibly more of an
issue with Ubuntu's repo than PHP itself. Nonetheless, try this and
reply to the list with the output of each:
php -v
php -r 'echo phpversion().PHP_EOL;'
php -nv
Also, while it does work with PHP, note that, with a few
exceptions such as `find`, *NIX CLI short options (single dash)
generally expect a single character, while long options
(double-dashes) take longer strings.

Yes, it would be php5-cli, but since he's getting the response
from PHP (parse error) and not the environment saying the command
isn't found, it shows he's got the CLI installed. Ubuntu is actually
really helpful with a lot of that, too, since - if it can't find the
command - it'll suggest packages from APT to install which match the
command given.

Apparently, the version of PHP installed on 12.04 accepts
"-version". The version of PHP installed on 12.10 does not, and bombs
without giving a proper error message.
Good to know.

Can I just mention, as so many others have, how much I hate the fact
that this list is configured to not reply to the list by default?
Thanks for forwarding this on to the right address, Dan.

I know. Actually, the only reason it's like this is because a lot
of people will take the conversations off-list on their own, so we
don't force the list as the reply-to address. After ~13 years,
though, it's difficult to justify the change.
No problem on the forward, though. Thanks for contributing to the
community.

since apache and cli do not share the same apc, it will not work.

Oh true, sorry, I totally forgot.
In that case, you can always do a wget or cURL request to your server forcing
it to clean APC cache through the webserver, I assume that if you're deploying
through symlinks you want a really minimal downtime during update, the only bad
thing about this method is that you need to protect the script from external
visitors through htaccess or similar methods if you're using other webservers.
Make the request like:
wget http://localhost/apc-clear.php -O /dev/null 2>&1
man wget for more information about how to use always the correct options.
If you are using Apache, you can also give a try with a graceful restart, in
red hat based systems, you would restart apache with:
/etc/init.d/httpd graceful
or
apachectl graceful
I have never tried this on a production machine so I really don't know if that
is gonna work, but the idea after this method is to:
"The USR1 or graceful signal causes the parent process to advise the children
to exit after their current request (or to exit immediately if they're not
serving anything)."
http://httpd.apache.org/docs/2.2/stopping.html#graceful
Hope this helps ^^
