PHP is one of the most requested features, but it is not yet supported in GAE, so your PHP code is useless. PHP是最需要的功能之一，但是GAE尚不支持PHP，因此您的PHP代码无用。 In the future, hosted SQL databases seem to be part of Google plans to provide "Enterprise features" in GAE, stay tuned because that could simplify what you need to do. 将来，托管SQL数据库似乎已成为Google计划在GAE中提供“企业功能”的一部分，敬请期待，因为这可以简化您的工作。

Currently, in case that: 目前，如果发生以下情况：

your site is implemented as a Java EE or Python web appliaction 您的网站以Java EE或Python网络应用程序的形式实现
you are already using JPA/JDO (only in the Java EE case) 您已经在使用JPA / JDO（仅在Java EE情况下）
you are not doing JOIN statements (not supported in GAE) 您没有执行JOIN语句（GAE不支持）

Or even if your service/dao layers are already well isolated, it would be possible to host your "denormalized" database (it would not be a postgres service) and your frontend in GAE without too much effort. 或者，即使您的服务/ Dao层已经很好地隔离，也可以不花太多精力在GAE上托管您的“非规范化”数据库（这不是Postgres服务）和您的前端。
