我建议你直接买一本PHP 5书。虽然PHP4中的所有内容都可以在PHP5中运行，但最好学习新功能

，例如PHP5中提供更好的OO支持。

嗨


不是真的，


PHP5与4相比有显着差异，尤其是

OOP类的使用，但是mysql和mysqli之间的差异并不是在PHP4书中显示的，只是因为mysqli只是用PHP5引入的。 />

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.
