Zend Framework requiere un intérprete PHP 5 con un servidor web configurado para manejar scripts PHP correctamente. Algunas características requieren extensiones adicionales o características de servidor web; en muchos casos el framework puede ser utilizado sin ellos, aunque el rendimiento puede sufrir o las características auxiliares pueden no ser completamente funcionales. Un ejemplo de dicha dependencia es mod_rewrite en un entorno Apache, que puede ser utilizado para ejecutar "pretty URL" como "http://www.example.com/user/edit". Si mod_rewrite no está habilitado, ZF puede ser configurado para apoyar las URL como. La pretty URL, puede ser utilizada para acortar las URL de representación textual o para la optimisation de los motores de búsqueda(SEO), pero no afectan directamente a la funcionalidad de la aplicación. Zend recomienda PHP 5.2.3 o superior por mejoras en la seguridad críticas y en el rendimiento, aunque Zend Framework requiere sólo PHP 5.1.4 o posterior. Zend Framework tiene una extensa colección de unidades de prueba, que puede ejecutar utilizando PHPUnit 3.0 o posterior. Usted encontrará un cuadro con todas las extensiones que suelen encontrarse en PHP y debajo cómo se usan en Zend Framework. Usted debe verificar que las extensiones de componentes ZF que estará usando en su aplicación están disponibles en sus entornos PHP. Muchas aplicaciones no exigirán de cada extensión que figuran a continuación. Una dependencia de tipo "hard" indica que los componentes o clases no pueden funcionar correctamente si las respectivas extensiones no están disponibles, mientras que una dependencia de tipo "soft" indica que el componente puede usar la extensión si está disponible pero funcionará correctamente si no lo está. Muchos de los componentes utilizarán automáticamente determinadas extensiones si están disponibles para optimizar el rendimiento pero ejecutarán el código con una funcionalidad similar en el propio componente si las extensiones no están disponibles.

Esto puede ayudar a guiarlo para saber que extensiones son necesarias para su aplicación. No todas las extensiones utilizados por Zend Framework son necesarias en cada aplicación. Una dependencia de tipo "hard" indica que los componentes o clases no pueden funcionar correctamente si las extensiones respectivas no están disponibles, mientras que una dependencia de tipo "soft" indica que el componente puede usar la extensión si está disponible, pero funcionará correctamente si no lo está. Muchos de los componentes utilizarán automáticamente determinadas extensiones si están disponibles para optimizar el rendimiento, pero ejecutará un código con una funcionalidad similar en el propio componente si las extensiones no están disponibles.

Esto puede ser de ayuda si usted necesita tener sólo componentes individuales en lugar del Zend Framework completo. Una dependencia de tipo "hard" indica que los componentes o clases no funcionarán correctamente si los respectivos componentes dependientes no están disponibles, mientras que una dependencia de tipo "soft" indica que el componente puede necesitar el componente dependiente en situaciones especiales o con adaptadores especiales. Incluso si es posible separar componentes indiduales para usarlo desde Zend Framework completo, usted debe tener en cuenta que esto puede conducir a problemas cuando se perdieron los ficheros o los componentes se utilizan dinámicamente.
