Here we have endeavored to present the databases as decreasing order of use cases with PHP. Thus the most prominent databases feature on the top while the less popular ones are listed further down.
在这里，我们努力以PHP用例的降序显示数据库。 因此，最著名的数据库位于顶部，而较不受欢迎的数据库则位于下方。
MySQL
MySQL
Certainly the most popular database out there for PHP applications is MySQL. It’s prominent open-source database all around the world besides there is the enterprise version of the database also available and it’s the paid one. A lot of popular applications such as SugarCRM, Magento, WordPress and Drupal are using MySQl while it has its customers in Wikipedia, Facebook and Google. With MySQL workbench you get a web based user interface useful in managing the database.
当然，PHP应用程序中最受欢迎的数据库是MySQL。 它是世界上著名的开源数据库，此外还提供企业版数据库，并且是付费数据库。 许多流行的应用程序(例如SugarCRM，Magento，WordPress和Drupal)都在使用MySQl，而它的客户来自Wikipedia，Facebook和Google。 使用MySQL工作台，您将获得基于Web的用户界面，对管理数据库非常有用。
PostGreSQL
PostGreSQL
Launched in 1995, PostGreSQL emphasize on compliance and standards. Comparatively to MySQL, PostGreSQL is feature rich while the database at present is under its release 9.3 compared to release 5.6 of MySQL. With advanced optimization and compression attribute, PostGrey is in the league of Oracle. Most prominent applications that use PostGreSQL are OpenBravo and PostERP among others. Meanwhile, as compared to MySQL, PostGreSQL is a fraction slower.
PostGreSQL成立于1995年，着重于合规性和标准。 与MySQL相比，PostGreSQL具有丰富的功能，而与MySQL 5.6版本相比，当前数据库处于9.3版之下。 凭借高级优化和压缩属性，PostGrey跻身Oracle联盟。 使用PostGreSQL的最杰出的应用程序包括OpenBravo和PostERP。 同时，与MySQL相比，PostGreSQL慢一点。
In case you mostly use Windows and having related infrastructure already, then it’d be advised using MS-SQL. However web developments that use .NET and .ASP technology are going to cost more. This is the reason some customers use PHP getting it connected to MS-SQL. At the same time also keep in mind that it works just for PHP version 5+ only.
如果您主要使用Windows且已经具有相关的基础结构，则建议使用MS-SQL。 但是，使用.NET和.ASP技术的Web开发的成本将更高。 这就是某些客户使用PHP将其连接到MS-SQL的原因。 同时还要记住，它仅适用于PHP 5+版本。
SYBASE
SYBASE
