Hey LorenzoNuniz,
Thanks for inspiring me to search some ebooks about java and PHP knowledge. I was also eager to learn PHP and Java. Now a days it's basic requirement for web masters to have these kind of technology and bit coding knowledge. 

Try this one http://www.w3schools.com/js/ . This is a great resource to learn Javascript.

There are so many websites available on the Internet. There are sites related to the Javascript are also on the Internet. But from the my point of view the best site is w3c school. All the information is given in the detail and in the easy language, so freshers can also understand it very well.
