Anybody here give me PHP keywords.?

I want the keywords such as operators, functions and so on, I want it to be a list, like when you search "HTML tags list" then it shows all the listed keywords for usage. Now I want the same with PHP. because I don't like strings and trying to memorize them. What I do is write down all the words on paper and so experiment that way with them.

If anyone knows kindly replay here.
