Can I learn PHP 5 with PHP 4 book?

[varois83]

Hi

I would like to learn PHP and I know we are at version 5. A friend
let me use 2 of his books but they cover PHP 4. Is that ok for
starting to learn the language? Or should I go straight with a PHP 5
book ?

Thanks a lot

I'd recommend going straight for a PHP 5 book. While virtually
everything in PHP4 works in PHP5, it's better to learn the new features
such as better OO support available in PHP5.

Hi

Not really,

there are significant differences in PHP5 compared to 4, especially the
OOP class use, but also differences between mysql and mysqli are not
shown in a PHP4 book, simply as mysqli has only been introduced with PHP5.

mysqli was introduced in PHP 4.1.

That's what I did - and it worked for me.
I've been on PHP4 since before the turn of the century.

Finally I switched IPP's and my new provider lets me toggle between PHP4
and PHP5 through a radio button on an HTML form. I finally made that
change about a week ago, even though PHP5's been around for a long time.

Best yet - all of my old PHP4 stuff still works, and what I learned
about the older version remains useful in the newer version.

The only learning curve I'm finding is that there's a whole bunch of new
stuff that you can do with classes and objects that you couldn't do
before.

mysqli was introduced in PHP 4.1.

mysqli is a PHP5 introduction.
you might've confused it with mySQL 4.1, as mysqli was designed to work
with more functions of mysql coming with v. 4.1+

quote php.net
"The mysqli extension allows you to access the functionality provided by
MySQL 4.1 and above"
( http://www.php.net/manual/en/ref.mysqli.php )

Exactly. The functions were available in PHP 4.1.

No, it wasn't. Andy is right. Read the link you provided yourself more
closely.

Mysqli requires a minimum *MYSQL* version of 4.1, not a minimum *PHP*
version of 4.1. The minimum PHP version required for mysqli is 5.0.

Everyone makes mistakes sometimes. ;-)

Read again. It's about _MySQL_ 4.1, not PHP 4.1. The MySQLi extension
was introduced with PHP 5 in 2004 (or 2003 if it was in beta already).
There's not a single entry about it in the PHP 4 changelog and the
manual clearly states "PHP 5" for all its functions.

Ah, yes, I did misread it. More than once, in fact! Thanks.

All this debate, and you should be using PDO anyway!

Naw, PDO is OK, and fine for others. But I have my own database class
hierarchy I developed before PDO came along.
