Zend Studio是Zend Technologies開發的PHP語言集成開發環境（Integrated Development Environment IDE)。也支持HTML和js標簽，但只對PHP語言提供調試支持。因為是同一個公司的產品，所以提供的Zend Framework方面的支持比其他軟件好。Zend Studio5.5系列後，官方推出利用了Eclipse平台，基於PDT的Zend Studio for Eclipse 6.0，之後的版本也都構建於Eclipse。
Zend Studio是屢獲大獎的專業 PHP 集成開發環境，具備功能強大的專業編輯工具和調試工具，支持PHP語法加亮顯示，支持語法自動填充功能，支持書簽功能，支持語法自動縮排和代碼復制功能，內置一個強大的PHP代碼調試工具，支持本地和遠程兩種調試模式，支持多種高級調試功能。
