We recently converted from a source version of Apache 2 to an RPM version. We wanted all of the PHP/MySQL stuff compiled in and working quickly. Yes, we were very lazy. Now, we tried to use our old httpd.conf file; however, since the compiled version had many of the options built in, our httpd.conf file […]

In this series of articles, we will explore the fundamentals of PHP programming with MySQL. For a good reference, try this book. It helped us.

What would you say if I told you that you could bring up a system that provided LAMP with two files: [usr-1@srv-1 Desktop]$ ls -l total 127720 -rw-rw-r– 1 usr-1 usr-1 88861055 Jul 2 03:37 stage3-i686-2004.3.tar.bz2 -rw-rw-r– 1 usr-1 usr-1 41779457 Jul 2 02:51 xampp-linux-1.4.14.tar.gz [usr-1@srv-1 Desktop]$ I’m talking bare metal here.

In Part 1 of this series, we set up a basic PHP server with Apache on a Red Hat system, and wrote a simple “Hello World” script. In this article, we will vary content based on browser type. We will use the HTTP_SERVER_VARS server variable. The specific variable we want is HTTP_SERVER_VARS[‘HTTP_USER_AGENT’]. To use this, […]

If you know exactly what modules you plan to use with a website, and you are sure you don’t need the flexibility of adding in those modules later, you can compile Apache with the modules built in. Here is the configuration statement for a minimal Apache compile with server side includes. This was for an […]

In this article we will pass a parameter to a PHP script via a URL, and we will get a little more sophisticated in our conditionals and regular expressions. One problem with accepting parameters is that there are often security issues. It is very important to ensure that the parameters passed by the user conform […]

To set a variable to the remote IP address of the client, use this: var ip = ‘<!–#echo var=”REMOTE_ADDR”–>’; Apache needs the include module either loaded or compiled in. Also, these options need to be specified in httpd.conf: AddHandler server-parsed .shtml AddOutputFilter INCLUDES .shtml Options Includes Check out this page for more information about SSI.

We aren’t quite happy with the web stats software we use. The information is not brief enough. Mostly, we want to see the last couple months, with the weekends visible, and the unique hosts and pages viewed. Also, we have a lot of content that gets snagged that isn’t really what we consider a valid […]

Geronimo is an open-source, certified J2EE server. The installation is really quite simple. The first thing we did was to make sure we had the latest Sun JDK from here and got rid of our included GCC Java: # rpm -e java-1.4.2-gcj-compat-1.4.2.0-27jpp # rpm -e gcc-java-3.4.3-22.1 [root@srv-1 java]# ls jdk-1_5_0_05-linux-i586-rpm.bin jre-1_5_0_04-linux-i586.rpm jre-1_5_0_04-linux-i586-rpm.bin [root@srv-1 java]# chmod […]

Like the needy stranger who tells us his or her entire life story on the occassion of our first meeting, Apache spews out way too much information in every HTTP header. And like the unscrupulous sharpies who take advantage of lonely folks they meet on buses, there are those who would use this information to […]

To load up a variable with the contents of a file with PHP, you can use this command: $filecontents=file_get_contents(“path to file”); One problem is that we had for this in our application was quotes. The text in the file had both ‘ and “. Magic quotes automatically convert quotes to escaped quotes so that when […]

One thing that is quite prevalent in forums is sharing images as postings or as avatars. We saw that our RoboCoop was getting some hits, and wondered what was up. Well, there is a forum that has a daily discussion in Texas here that had put up a link to the image of our chicken […]

We wrote about the XAMPP project in this article. This project is perfect for maintaining a cross platform dev environment for an application we are currently working on. Most of the work is done on OS X, but we also do some work on GNU/Linux. Further, the target audience for this may very well use […]

We often need to convert source code into html format. We use the pre tag; however, the default tab values are to wide. For instance: this is one tab this is another If we were to put some of our funner source code up, it would push the right margin over too far. Well, we […]
