mysql php php5

谁告诉我PHP 5系列与PHP 4系列有什么不同,
谁告诉我PHP   5系列与PHP   4系列有什么不同,目前我只发现PHP   5系列不把MYSQL作为内置数据库,还有什么别的不同吗?

------解决方案--------------------
谁说的。PHP6中才取消MYSQL函数呢。统一用PDO。
------解决方案--------------------
PHP4与PHP5的字符编码方式不同!
------解决方案--------------------
to axaw:
php5确实已经不是默认有mysql_系列函数了,要支持必须在编译的时候增加--with-mysql选项.

to yiqing666:
php4和php5在字符编码方面,无任何区别。而php6只是内建了对unicode的支持。一个很明显的例子是,strlen( "中文 ")在php4或者php5里,会得到4(gbk)或者6(utf-8)的结果,而在php6里,则是返回2。


php5和php4最大的区别是在面向对象方面。具体可以去阅读php的手册。

------解决方案--------------------
哎~什么话都被楼上的说了……

偶接分……

建议楼主参考php5的官方文档,里面详细的阐述了php4和php5的区别
------解决方案--------------------
难道你编译PHP的时候没有加--with-mysql选项。呵呵。

这两年都用5在开发,4的时候好像直接就支持的。呵呵。

要用发展的眼光啊,都快6了,还在用古老的4.

我们的目标是要用PHP写CNINUX
