    <title>Requisitos de Zend Framework</title>
    <para>
        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.

        <title>Versión de PHP</title>

        <para>
            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.
        </para>

        <para>
            Zend Framework tiene una extensa colección de unidades de prueba, 
            que puede ejecutar utilizando PHPUnit 3.0 o posterior.

        <title>Extensiones de PHP</title>

        <para>
            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.
        </para>

        <para>
            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.

        <para>
            Más abajo hay un cuadro que enumera todos los Componentes de 
            Zend Framework y que extensión de PHP necesitan. 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.
        </para>

        <para>
            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.

            A continuación encontrará un cuadro de Componennetes de 
            Zend Framework y sus dependencias a otros Componentes de Zend 
            Framework. Esto puede ser de ayuda si usted necesita tener sólo 
            componentes individuales en lugar del Zend Framework completo.

        <para>
            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.
        </para>

        <note>
            <para>
                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.
