This is a guide to save you from banging your head against a wall, in case you ever want to get PHP talk with Ingres on a CentOS machine.
After hours of searching around and not finding not one damn proper guide, I decided to just write one down (after much trial and error).
What we wanna do is basically query an Ingres database through a CentOS based LAMP server (which runs WHM/CPanel too). So we need to install (unfortunately) the Ingres Community Database (as the PECL Ingres package seems to require it to be installed) and of course we need to install PHP's package for Ingres (PECL Ingres) so we can query an Ingres database from PHP. Still with me?
Let's get started...
1. Install Ingres and PHP/Ingres support on CentOS:
Install Ingres DB Community Edition first as it's obviously required by PECL's Ingres package. Here we install the related RPM for a 32-bit CentOS machine. The process is the same for 64-bit, the file is just different. Sign up on ingres.com for a free account and go to http://www.ingres.com/downloads/ingres-database.php to download the right release. Ingres.com is passing the download link from some script, so if you wanna pinpoint the URL and not download the file to your PC, then upload onto your server, you can simply right-click on the download manager in Firefox and copy the "link location". This will give you the URL where the actual file of the Ingres db relies on the ingres.com site, so you can use "wget". In this case, the path I got was something like "http://220.127.116.11/~GqxCOi/ingres-10.0.0-119-NPTL-gpl-pc-linux-i386.tgz". Don't try this link in particular as it may not work when you read this...
You obviously need root access to the server:
# cd /usr/src # wget http://18.104.22.168/~GqxCOi/ingres-10.0.0-119-NPTL-gpl-pc-linux-i386.tgz # tar -zxvf ingres-10.0.0-119-NPTL-gpl-pc-linux-i386.tgz # cd ingres-10.0.0-119-NPTL-gpl-pc-linux-i386 # sh ingres_express_install.sh
This process will install Ingres in /opt/Ingres/IngresII/2. Install the PECL Ingres package for PHP.
Using "pecl install ingres" will simply NOT work. So we do it the old-fashioned way. Grab the latest package here: http://pecl.php.net/package/ingres and then do the following:
# cd /usr/src # wget http://pecl.php.net/get/ingres-2.2.2.tgz # tar -zxvf ingres-2.2.2.tgz # cd ingres-2.2.2 # phpize # ./configure --with-ingres=/opt/Ingres/IngresII # make # make install
This process will install the PECL Ingres package for PHP.We need a couple more things, before we get started.
We need to declare some system variables in Apache. If you use WHM/CPanel, go to Main >> Service Configuration >> Apache Configuration >> Include Editor and choose to edit the "Pre Main Include" file. Add the following 2 lines:
SetEnv II_SYSTEM /opt/Ingres/IngresII SetEnv LD_LIBRARY_PATH /opt/Ingres/IngresII/ingres/lib
If you don't use Cpanel, just paste these lines into your httpd.conf file.Now locate the WHM/CPanel php.ini file at /usr/local/lib/php.ini (if you don't use WHM/Cpanel it's probably located in /usr/lib/php.ini). Find the line "; Directory in which the loadable extensions (modules) reside." and right after that add:
extension = "ingres.so"
This will make sure the related PHP extension for Ingres support is loaded by PHP.That's it.Go to your "public_html" folder (or any other folder) and test if you got Ingres support for PHP installed properly. We'll use a dummy connection file, so get the code below:
<?php $link = ingres_connect("database", "user", "password") or die("Could not connect: " . ingres_error($link)); echo "Connected successfully"; ?>
…and save this as "ingres.php". Now visit this file from your browser and if you get a "Warning: ingres_connect()..." then it means Ingress support for PHP is installed properly!Enjoy!
Here's an easy trick to replace the built-in Mootools library that comes in Joomla 1.5 with a compressed copy from Google AJAX Libraries API:
There are 2 speed benefits by following this approach:
- We load a compressed copy of Mootools, so from around 73kb it drops to 18kb!
- We load Mootools from Google, thus our browser can simultaneously (in parallel) download Mootools along with the rest of our site's content.
It's a simple & easy trick we use on all our web projects, big or small. ;)
- Establish naming conventions. Do not assume you'll always be the one coding for a particular site. Never use generic names for classes, IDs and form names in your code like “comment” or “article”. Someone else may do so too, so you can kiss your app’s functionality bye-bye!
- Avoid inline CSS like the plague.
- Try to squeeze as much CSS code as possible into one file. Less CSS files means faster loading of your site's design on the browser.
- Avoid placing UI images inside your HTML code. UI images belong to given UI templates (home, category lists, product catalog, article etc.) and therefore are loaded on every page request. Placing such images as "background images" in your CSS file allows the browser to cache them the first time it renders them, which means your site will load faster on subsequent requests for your visitors.
- If you code on PHP, check out the Tidy library. Enable it when you can as it will easily point out (and fix) bad markup in your HTML.
- For God’s sake use an open source CMS, don’t re-invent the wheel, make it possible to contribute back. Joomla, Drupal, Wordpress are enterprise class CMSs to get started with and some of the most popular websites in the world are powered by these open source CMSs.
I was recently looking for a clean solution to prevent the display of module positions on gazzetta.gr - the 2nd most high traffic Joomla website, after joomla.org.
The first thing that came to mind was the htaccess trick I had spotted on the Joomla forums here: http://forum.joomla.org/viewtopic.php?p=1887090#p1887090
Thing is, this rule does not work if you have SEF on and you’re in some inside page.
So I just wrote a simple solution which is PHP based and you can include right at the top of your Joomla template for ease of maintenance (template designers can use this too as an XML option ;) )…
Make sure the following code goes at the very top of your template's index.php file, but within <?php and ?> tags:
// Properly prevent ?tp=1 module position exposure on Joomla sites using PHP only$currentURL = explode('?',substr(JURI::base(),0,-1).$_SERVER['REQUEST_URI']);if($_GET['tp']) header('Location: '.$currentURL);
UPDATE: There seems to be a Joomla API solution for that. Thanks to Cory Webb for letting me know. Both solution follow...
