Recommend some functions

[Jutlander]

I've begun to learn PHP again, have tried a few times before but can't seem to get the same hang of it like HTML and CSS. :o

Well, I can do the very basics, but would like to start using some functions and such. Can you recommend some good functions for a beginner, that are nice to know of? I know of some already, namely:

include() and require()
rand()
date()
count()
mail() - don't want to make a mailform though as I have one that is fully working

I was hoping someone could recommend some new ones to learn. :)

In addition to learning more functions, you might want to learn some good techniques/habits.

Such as mastering how and when to use different types of loops.


var_dump() (http://www.php.net/var-dump)
print_r() (http://www.php.net/print-r)
These functions are important when you are debugging.

You also might want to inform of which PHP version you are using.

Looking over the manual will definitely help you get an understanding, as well as hands on experience, of course.
