I dont know of a single course to encompass all the technologies...my associates focus was in web technologies from the commuinity college here, but that is kind of generic encompassing many different languages, databases, etc.
So to become educated specifically in LAMP you may want to do your own track. This is how I learned:
LINUX: The college here is RedHat Academy, I took several courses then supplemented that and then became certified (RHCSA)...I reccommend RedHat based distros since you mention "international" and RedHat is the largest in the US, and I like the simple yet secure server platform setup out of the box.
APACHE: Basics are covered in the redhat training and certifications, beyond that there is a lot of info online.
MYSQL: The schools around here are focused on MSSql or Oracle which is good for the concepts but you need supplemental training in MYSQL, which Oracle now offers courses in or you can enroll in an online course.
PHP: Again, not very much offered in schools but I had a background in perl, C++ and Basic so subscribing to online courses through Lynda.com and other places was very beneficial.
