MySQL new library and notepad++

Question

As I understand it, the normal mysql mysql.* method library has been superseded somewhat by the library mysqli.*. Essentially, my understanding is that the new library uses all the old methods just with the letter "i" tagged onto the end of the method name. Three questions:

1. Why have MySQL updated this library and what new features does it contain?
2. For users of Notepad++, the language of choice can be selected from a drop-down menu, which then highlights the code much like an IDE does, for instance methods are coloured blue and are in bold font. When I first wrote some MySQL code, I used the old library methods, not being aware of the advancement. When I converted it to the new library methods, the blue/bold highlighting disappeared and returned to normal font. When I deleted the "i" in the method name, it became highlighted again. Why does Notepad++ not recognize the new methods?
3. Are the new methods a requirement (i.e. Will the old methods still work in PHP)?

Solution 1

Using Notepad++, highlight mysqli, then

1. open note pad select settings
2. select style configurator
3. in language select php
4. in style select WORD
5. in user-defined key words enter the keyword you want highlighted.
   make sure there is a space after false (first item.)
   Below is a list (It's the ones I use.)
6. Save and close.

Solution 2

I can't answer number 1 for you because I don't know the details.

2: I don't know why it's not included by default, but you can add it manually.
Go to settings->style configurator and choose php under language. Choose WORD under style.
In the box called "User-defined keywords" Add all the mysqli_* functions you use. They'll be highlighted from now on.

3: For now, they will work. It was deprecated in 5.5, which means it will throw a warning when you use it. Eventually, it will be completely removed. Still, switch over to mysqli so nothing breaks when you upgrade.

MySQLi is not different from MySQL. Here's the usual message we usually give to people using mysql_*: Please, don't use mysql_* functions in new code. They are no longer maintained and are officially deprecated. See the red box? Learn about prepared statements instead, and use PDO or MySQLi - this article will help you decide which. If you choose PDO, here is a good tutorial.
