你会想要的yum install php53。不幸的是，您需要先删除php（即 php 5.1，见下文）。

php53 在CentOS 5.6 及以上版本的CentOS 中可用。它在 CentOS 5.5 及更早版本中不可用，除非您通过第三方存储库。这就是为什么 Serverfault 上的许多答案都告诉您使用第三方存储库的原因——这不再是必要的了。

请注意，php53 有许多依赖项，因此您应该考虑将 CentOS 更新到最新的 CentOS 5.x 分支作为此次升级的一部分（在撰写本文时为 CentOS 5.6）。这是 PHP 的一次重大升级，RedHat 强行通过，因为它们在 RHEL5.5 时已经落后于时代。

注意包是如何命名的php53，而phpphp 5.1 是：

$ yum info php53
