Here we guide you through what you should be doing - using PHP's MySQLi class - with a hat-tip to the one way that you definitely shouldn't be doing it.
The Wrong Way If you're using a function called mysql_connect() or mysql_query() you really need to take note and change what you're doing. I understand that it's not easy to change current large projects, but look to change future ones. Any of the functions that are prefixed with mysql_ are now being discouraged by PHP themselves as visible on this doc page, instead you should look to use one of the following: Each has its advantages, PDO for example will work with various different database systems, where as MySQLi will only work with MySQL databases.

I’ll be sharing few awesome learning resources I’ve bookmarked, and will be pointing out some specific computer/programming related courses I've found interesting from these resources. Also, thought about saving this blog post for my kids as well - instead of investing in these Child education schemes (though they are too small as of today, 2 years and 60 days respectively ). Anyway, personally my new year resolution is to see as much videos from this course collections (assuming I can find some free time in between my regular job && changing my babies diapers). 1 – Khan Academy As I mentioned some time back, you and your kids are missing some thing huge if you havn’t heard about Khan Academy.
It is an awesome learning resource, especially if you want to re-visit your basics in Math, Science etc. 2 – MIT Open Courseware and Videos Just in case you are not aware, MIT has a huge collection of open courses, bookmark. Sass vs. LESS. "Which CSS preprocessor language should I choose? " is a hot topic lately. I've been asked in person several times and an online debate has been popping up every few days it seems. It's nice that the conversation has largely turned from whether or not preprocessing is a good idea to which one language is best. Let's do this thing. Really short answer: Sass Slightly longer answer: Sass is better on a whole bunch of different fronts, but if you are already happy in LESS, that's cool, at least you are doing yourself a favor by preprocessing.
Much longer answer: Read on. The Much Longer Answer The Learning Curve with Ruby and Command Line and Whatever The only learning curve is the syntax. Winner: Nobody Helping with CSS3 With either language, you can write your own mixins to help with vendor prefixes. In Sass, you can use Compass, and Compass will keep itself updated, and thus the prefix situation is handled for you. In LESS, there are also some mixin libraries battling to be the best. See that? Easy Server Side Caching in PHP. When developing dynamic web applications there may be many times that data is not updated for a certain amount of time. In PHP it is fairly simple to have a page cached, so that there is not much load on the server. To create this caching you would put some code like the following on the top of your PHP page.
$cachefile = 'caching_folder/cachedpage.html'; $cachetime = 30; // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && time() - $cachetime < filemtime($cachefile)) { include($cachefile); exit; } ob_start(); // Start the output buffer The things that you would change in the above code is the setting of the $cachfile variable to the name of the static file that the cache will be saving on the server (you will need to set permissions on the folder where you want to save the cached file). You will also want to change the $cachetime variable to the number of seconds between each caching. C# Source Code , Development , Programming , Free source code. Discover Everything through Code.
