In this tutorial I will show you how to check whether a domain, server is up or down and how fast it is. Generally speaking we will implement a ping command with PHP.
Creating a Website / Server Monitoring Script PHP / Site Analysis
I have created a script which allows users to check to see if their server is online. Obviously running this script from the same server and trying to check your server status whilst its down its too clever, so try using an include or iframe from a free hosting company.
Check the status of a page PHP / Miscellaneous
Sometimes it is useful to know whether a certain website is online or if it is down. This could be part of a more complex script, so even just a simple status page. Either way, the principle is the same.
Exec and system command and results PHP / Miscellaneous
This tutorial will show you how to run exec commands and system commands from php using a form, you do not need a database to run these commands but you do need permission to be able to run command line commands from PHP. This tutorial will show you how to do this using an example with the "ping" command, in short we will go through how to ping and display the results via browser.

Storing Data in the Client PHP / Miscellaneous
One of the things that all programmers love is to write a program which writes another program. On the web we have two different programming environments: the client (browser) and the server. Due to the HTTP protocol definition we can write a program on the server which writes another program to be executed on the client. Let's pick PHP (of course) for the server and JavaScript for the client. We'll show you in this article how you can use this scheme to store data in the client and then minimize the data transfered between the server and the browser for interactive applications like a chat room, a news system or whatever you want.
File System PHP / File Operations
One of the most useful features of a server side language is its ability to interface with the file system on the server that hosts the website. This feature clearly distinguishes the language from a client side language such as JavaScript. While JavaScript is sent down to the client's browser and is then interpreted on their computer, server side languages such as PHP are interpreted and resolved on the server, and only the end result is sent down to the client's browser. It is because of this fact that the language has the ability to interface with the files on the server. PHP has the ability to work with both text files and sophisticated database systems. This part of the tutorial discusses text files; we'll get into databases later.
Cookies PHP / Sessions and Cookies
A cookie is a message given to a Web browser by a Web server. The browser stores the message in a small text file that the server embeds on the user's computer. Each time the same computer requests a page with a browser, the cookie is sent back to the server too.
There are a wide variety of things you can do with cookies. They are used to store information about user, visited pages, poll results and etc.
Customizing PHP Safe Mode PHP / Security
We'll guide you through using PHP safe_mode and how-to enable it and to customize it for certain sites on your server. When using PHP as an Apache module, you can also change the configuration settings using directives in Apache configuration files (e.g. httpd.conf) and .htaccess files. PHP safe_mode is very important to in terms of server security because it restricts and disables the dangerous functions in PHP from the scripts like PHP Shell that can otherwise cause damages to your server and client sites.
IXSSO Queries PHP / Miscellaneous
It's hard to find good information about querying Microsofts Indexing Server through PHP. In fact many people don't even know that it's possible. If you have a PHP website running off a Windows Server and you have several documents you want to be searchable from your site, then this is an important skill to know.
