[PHP] Newbie is trying to set up OOP With PHP and MySQL or MySQLi database class (using CRUD)
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... http://net.tutsplus.com/tutorials/php/real-world-oop-with-php-and-mysql/ http://www.dreamincode.net/forums/topic/223360-connect-to-your-database-using-oop-php5-with-mysql-and-mysqli/ http://snipplr.com/view/8417/ http://snipplr.com/view/12535/ any assistance is appreciated! -- Thanks, Dave - DealTek deal...@gmail.com [db-3] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

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=revisionrevision=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=revisionrevision=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.

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.

I'm pretty sure the php5 package in ubuntu doesn't include the cli client. Try adding apt-get install php5-cli (or whatever they're calling the package these days) and see if the version command works then. Also, you may need a second hyphen before the word version. 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. -- /Daniel P.

There is no reason, ever, that production code should raise notices about which

be wrong! And if you're investigating the code already, figure out what's
happening and deal with it properly.

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:redError display and logging
on/span ';
}

I put this at a convenient place on the page so I don't forget to turn off the

Note that if you're using PHP5 you should remove the before the $a in the
function definition.

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? I'm pretty sure the php5 package in ubuntu doesn't include the cli client. Try adding apt-get install php5-cli (or whatever they're calling the package these days) and see if the version command works then. Also, you may need a second hyphen before the word version. 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. -- /Daniel P.

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. -- /Daniel P.

Re: [PHP] APC opcode cache behavior

(can also be a command such as php -r apc_clear_cache();). This way you'll avoid restarting the webserver and it will clear all APC cache forcing APC to cache everything again. since apache and cli do not share the same apc, it will not work. -- Marco Behnke Dipl.

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 21 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 ^^ Met vriendelijke groet, Camilo Sperberg W: http://unreal4u.com T: http://twitter.com/unreal4u -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
