Test

Visit localhost/phpinfo in your web browser. You should see the infamous phpinfo output. If the address bar changes to somthing other than http://localhost/phpinfo/, than somthing went wrong while following the instructions and your browser has interpreted this as a search. Try following the instruction again. If it still doesn't work, send me an email via my contact page and let me know somthing isn't working right. If it did work, you have successfully installed PHP.
