Zend Studio是Zend Technologies开发的PHP语言集成开发环境（Integrated Development Environment IDE)。也支持HTML和js标签，但只对PHP语言提供调试支持。因为是同一个公司的产品，所以提供的Zend Framework方面的支持比其他软件好。Zend Studio5.5系列后，官方推出利用了Eclipse平台，基于PDT的Zend Studio for Eclipse 6.0，之后的版本也都构建于Eclipse。
Zend Studio是屡获大奖的专业 PHP 集成开发环境，具备功能强大的专业编辑工具和调试工具，支持PHP语法加亮显示，支持语法自动填充功能，支持书签功能，支持语法自动缩排和代码复制功能，内置一个强大的PHP代码调试工具，支持本地和远程两种调试模式，支持多种高级调试功能。
