Running PHP on Google App Engine

What is Google App Engine?
As some of you may remember, about 1 year ago, I posted an article about Google App Engine, a cloud computing environment that Google has been working on to host Web applications in a way that, in theory, it provides automatic scalability, so sites can handle large audiences without having to plan and invest on servers to handle large loads.

* Google App Engine with Java support
As it is explained in the article above, initially Google only provided support to run Python applications.

Meanwhile, last week Google announced the support of Java to run applications on Google App Engine.

* Running PHP applications on Google App Engine
As some of you may be aware, thanks to Quercus project, it is possible to run PHP 5 applications on environments that have a running Java Virtual Machine.

A PHP developer named Roshan just reported that he successfully run a PHP application on Google AppEngine using Quercus.

Here you may learn more details about this experience:

* Share your experiences with PHP on Google AppEngine
This is not an ideal solution because it is not native PHP support, as many of use hoped, but it is indeed some progress.

It would be interesting if anybody could share your results, specifically what are the limitations and what are the benefits of running PHP on this environment compared to traditional hosting environments.

As a side comment, PHP applications can also run wherever there is a .NET virtual machine, thanks to the Phalanger project, which by the way is sponsored by Microsoft.

So, in theory it should be possible to run PHP applications in Windows Azure, Microsoft cloud computing environment, as it was explained in this article:

If you have tried running PHP on these cloud computing environments, feel free to post your comments here.

PHP / SQL Security – The Big Picture

Web Security Whether your site is the web presence for a large multinational, a gallery showing your product range and inviting potential customers to come into the shop, or a personal site exhibiting your holiday photos, web security matters. After the hard work put in to make your site look good and respond to your users, the last thing you want is for a malicious hacker to come along, perform a PHP hack and break it somehow. There are a number of problems in web security, and unfortunately not all of them have definite solutions, but here we'll look at some of the problems that should be considered every time you set out to write a PHP script to avoid a PHP hack attack. These are the problems which, with well-designed code, can be eliminated entirely. Before looking in detail at the solutions, though, lets take a moment to define the problems themselves. SQL Injection In this attack, a user is able to execute SQL queries in your website's database. This attack is u...

PHP / SQL Security – SQL Commands and Non-String Variables

SQL Injection SQL (Structured Query Language) is the language used to interface with many database systems, including MySQL, PostgreSQL and MSSQL. Certain words and characters are interpreted specially by SQL, as commands, separators, or command terminators, for instance. When a user enters data into a form, there is nothing stopping them entering these special commands and characters. Consider the PHP code below: $query = “INSERT INTO orders(address) VALUES('$_GET['address']')”; $result = mysql_query($query); A form with a textbox named address would be used to gather the information for this page. We'll ignore any other form elements for now, but obviously there'd be the order items, a name, possibly a price, a delivery date, and so on, which would also all need storing in a database. Imagine a perfectly legitimate user comes along and enters the following address 14 King's Way Kingston Kingham County The database would spit back an error b...
