Hostgator的所有服务器都使用php 5，默认的php版本取决于你的主机类型，注意:如果您想使用一个特定版本的PHP,请参阅我们的文章 PHP 5.3 和 PHP 5.4 详情。
Hostgator也可以在VPS和专用服务器上安装 PHP 5.4
二次安装PHP(包括5.3和5.4)是免费的。
不幸的是,对于共享&经销商托管,不可能切换到一个服务器和一个特定版本的PHP。 所有新账户将使用PHP 5.3和PHP 5.4。 更早的帐户则只能继续使用PHP 5.2。 不过因为PHP 5.2是尽早要被弃用和被淘汰的，所以为了未来的兼容性，建议您准备一下，让你的脚本兼能够容PHP 5.3或PHP 5.4。
