        <title>Catching an Exception</title>
        <para>
            The following code listing demonstrates how to catch an exception thrown in a Zend Framework class:
        </para>
        <programlisting role="php"><![CDATA[
try {
    // Calling Zend_Loader::loadClass() with a non-existant class will cause
    // an exception to be thrown in Zend_Loader
    Zend_Loader::loadClass('nonexistantclass');
} catch (Zend_Exception $e) {
    echo "Caught exception: " . get_class($e) . "\n";
    echo "Message: " . $e->getMessage() . "\n";
    // Other code to recover from the error
}
]]></programlisting>
    </example>
    <para>
        <classname>Zend_Exception</classname> can be used as a catch-all exception class in a
        catch block to trap all exceptions thrown by Zend Framework classes. This can
        be useful when the program can not recover by catching a specific exception type.
    </para>

    <para>
        The documentation for each Zend Framework
        component and class will contain specific information on which methods
        throw exceptions, the circumstances that cause an exception to be thrown,
        and the class of all exceptions that may be thrown.
    </para>
