    <title>Using Exceptions</title>

    <para>
        <classname>Zend_Exception</classname> is simply the base class for all
        exceptions thrown within Zend Framework. </para>

    <example id="zend.exception.using.example">
        <title>Catching an Exception</title>
        <para> The following code listing demonstrates how to catch an exception
            thrown in a Zend Framework class: </para>
        <programlisting language="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>
