    <title>Zend Framework Requirements</title>

    <para>
        Zend Framework requires a PHP 5 interpreter with a web server configured
        to handle PHP scripts correctly. Some features require additional extensions or
        web server features; in most cases the framework can be used without them, although
        performance may suffer or ancillary features may not be fully functional. An example
        of such a dependency is mod_rewrite in an Apache environment, which can be used to
        implement "pretty URL's" like "http://www.example.com/user/edit". If mod_rewrite is
        not enabled, ZF can be configured to support URL's such as "http://www.example.com?controller=user&amp;action=edit".
        Pretty URL's may be used to shorten URL's for textual representation or search engine optimization (SEO),
        but they do not directly affect the functionality of the application.
    </para>

    <sect1 id="requirements.version">

        <title>PHP Version</title>

        <para>
            Zend recommends PHP 5.2.3 or higher for critical security and performance enhancements, although
            Zend Framework requires only PHP 5.1.4 or later.
        </para>

        <para>
            Zend Framework has an extensive collection of unit tests, which you can run using PHPUnit 3.0 or later.
        </para>

    </sect1>

    <sect1 id="requirements.extensions">

        <title>PHP Extensions</title>

        <para>
            You will find a table listing all extensions typically found in PHP
            and how they are used in Zend Framework below. You should verify that the extensions on
            which ZF components you'll be using in your application are available in your PHP environments.
            Many applications will not require every extension listed below.
        </para>

        <para>
            A dependency of type "hard" indicates that the components or classes
            cannot function properly if the respective extension is not available,
            while a dependency of type "soft" indicates that the component may use
            the extension if it is available but will function properly if it is not.
            Many components will automatically use certain extensions if they are available
            to optimize performance but will execute code with similar functionality in the
            component itself if the extensions are unavailable.

        <para>
            Below is a table that lists all available Zend Framework Components
            and which PHP extension they need. This can help guide you
            to know which extensions are required for your application.
            Not all extensions used by Zend Framework are required for every
            application.
        </para>

        <para>
            A dependency of type "hard" indicates that the components or classes
            cannot function properly if the respective extension is not available,
            while a dependency of type "soft" indicates that the component may use
            the extension if it is available but will function properly if it is not.
            Many components will automatically use certain extensions if they are available
            to optimize performance but will execute code with similar functionality in the
            component itself if the extensions are unavailable.

        <para>
            Below you can find a table listing Zend Framework Components
            and their dependencies to other Zend Framework Components. This
            can help you if you need to have only single components instead
            of the complete Zend Framework.
        </para>

        <para>
            A dependency of type "hard" indicates that the components or classes
            cannot function properly if the respective dependent component is not available,
            while a dependency of type "soft" indicates that the component may need
            the dependent component in special situations or with special adapters.
        </para>

        <note>
            <para>
                Even if it's possible to seperate single components for
                usage from the complete Zend Framework you should keep
                in mind that this can lead to problems when files are missed
                or components are used dynamically.
