How to Install Apache, PHP and MySQL on CentOS

How to, Linux, OpenSource, PHP, Resources, Tips and Tricks, Tutorials
I have seen people installing Apache, PHP and MySQL from source code on a production server. You should NEVER, NEVER, NEVER install these packages from source on an RPM or DEB based Linux distributions. Did I say “NEVER” enough times to make your realize that it is not a good practice? Installing from source is bad idea; there are many reasons for this but the major one is that you will be spending a lot of time keeping the system updated. If you love installing from source then I would suggest using a different distribution e.g. Gentoo. You can build from source if the package is not available in yum but still, try to use “yum” (or “apt-get” on Ubuntu) because it will save a lot of your time when…

Creating and Installing crontabs using CodeIgniter

How to, OpenSource, PHP, Resources, Reviews, Tips and Tricks, Tutorials
Last night, I was trying to get a crontab working in CodeIgniter, since my current project (a personal project) is using CodeIgniter now. I didn't wanted to use the conventional approach of running crontabs and my code seperate. Unfortunately, CodeIgniter does not have support for Crontabs and I didn't wanted to user wget in linux crontab to initiate unwanted requests. I spent some time and came up with a solution. It uses CodeIgniter backend Does not modify any core architecture of CodeIgniter Keeps configuration at one place So enough of the summary and let me show you how its done. Create a file (e.g. cron.php) in the same place as your index.php and system folder. Here is its code Now, we need a controller e.g. test so the controller code…

Template Library for CodeIgniter, Simple, Fast and Easy!

How to, OpenSource, PHP, Resources, Reviews, Tips and Tricks, Tutorials
If you have not noticed, I just got started on CodeIgniter. I was really disappointed today when I noticed the lack of a template system in CodeIngiter to skin my little application. They say The Template Parser Class is not a full-blown template parsing solution. We've kept it very lean on purpose in order to maintain maximum performance. Lucky for me, I got a little help here, the library is great and works well for the latest version of CI too best of all its small and does not modify the CI code in anyway. It just uses the already available code to skin the application. Sleak! I made a couple of modifications in the original library, here are my modifications So now I use it like instead of Hope…
