昨日，在php官网上php5.2.x系列稳定版更新到php5.2.14，PHP5.3.x系列更新到PHP5.3.3。同时这个版本主要改进了 PHP5.2.x系列的稳定性，修复60多个BUG，部分BUG与安全相关。这个版本标志着对PHP5.2系列更新的结束，在此版本之后不再积极更新 PHP5.2x，其安全补丁可能以单个形式发布。
与此同时，PHP开发团队发布了PHP5.3.3，修复了近100个BUG，鼓励所有PHP5.2系列的用户升级到PHP5.3。 但是实际上国内很多PHP程序对PHP5.3的支持都有不少小问题。
此外，PHP官网着重列出一个PHP5.3.3新的不兼容特性：在命名空间里，和类名一致的函数不再被作为一个构造函数。不过没有使用namespace的类不受影响。
<?php
namespace Foo;
class Bar {
public function Bar() {
// 在PHP 5.3.0-5.3.2版本作为构造函数
// 在PHP 5.3.3作为一个普通函数
}
} ?>
