There is lot of talk nowadays about PHP being enterprise ready and suitable for critical
business applications. Support from Industry biggies like IBM etc is fueling this idea.

Reports by yahoo that it has ported most of its web properties to php has helped if you need more info on this go to Michael’s website he has a nice presentation on php at yahoo.
If an industry leader like yahoo thinks that PHP has the requirements to meet its demands then i think other vendors who are using web applications developed in other scripting languages should
definitely think about porting it to the LAMP (LINUX-APACHE-MYSQL-PHP) stack.

I have had systems deployed on the LAMP stack and had the systems developed on the WAMP(WINDOWS-APACHE-MYSQL-PHP) stack have had no problems so far that is the beauty of AMP development platform if you dont depend on system specific functions then the system can be developed on LAMP or WAMP and deployed on WAMP or LAMP.

LAMP stack is good for deployment because it is highly robust and can meet the demands of a growing business but WAMP is good for developement because many of the programmers who are starting out are familiar with windows and since PHP is easy for anyone who is coming from a computer background where you have to tackle the likes of c,c++ etc this Stack forms a great place for them to start and get used to the three core components apache,mysql and php and have noticed that people sharpen their core skills of web projects rather then struggling to study the
concepts of linux and this people once they have appropriate skills can be just taught linux
at user level and the entire development team shifted to the WAMP stack.

Now with broadband being common place and all the talk about how ajax is going to replace most of the desktop applications i think PHP stands a very good chance on becoming the choice of many industry innovators in building and delivering cutting edge next generation web applications.
