Who told me what is the difference between the PHP 5 Series and the PHP 4 series? currently, I only find that the PHP 5 series does not use MYSQL as a built-in database. Is there any other difference?
------ Solution --------------------
Who said it. In PHP6, the MYSQL function is canceled. Use PDO.
------ Solution --------------------
PHP4 and PHP5 have different character encoding methods!
------ Solution --------------------
To axaw:
Php5 does not have the mysql _ series functions by default. to support it, you must add the -- with-mysql option during compilation.
To yiqing666:
Php4 and php5 have no difference in character encoding. Php6 only has built-in unicode support. An obvious example is that strlen ("Chinese") in php4 or php5 will get 4 (gbk) or 6 (UTF-8) results, while in php6, returns 2.
The biggest difference between php5 and php4 is in the object-oriented aspect. For more information, see The php Manual.

Didn't you add the -- with-mysql option when compiling PHP. Haha.
In the past two years, five developers have been used, and four developers seem to support them directly. Haha.
We need to develop our eyes. it's almost six times, and we are still using the ancient 4.
Our goal is to use PHP to write CNINUX
