            The method <methodname>getDefault()</methodname> returns an array of relevant locales
            using information from the user's web browser (if available), information from the
            environment of the host server, and Zend Framework settings. As with the constructor
            for <classname>Zend_Locale</classname>, the first parameter selects a preference of
            which information to consider <link

                <constant>ENVIRONMENT</constant>, or <code>FRAMEWORK)</code></link> first. The
            second parameter toggles between returning all matching locales or only the first/best
            match. Locale-aware components normally use only the first locale. A quality rating is
            included, when available.

            accepts some different types than the <methodname>getTranslationList()</methodname>
            method. Also value is the same as before with one difference. You have to give the

                Because you have almost always give a value as detail this parameter has to be given

            Sometimes you will want to get a list of all known locales. This can be used for several

        <title>Detecting locales</title>

        <para>
            When you want to detect if a given input, regardless of its source, is a locale you
            should use the static <methodname>isLocale()</methodname> method. The first parameter of
            this method is the string which you want to check.
        </para>

        <example id="zend.locale.detection.example-1">
            <title>Simple locale detection</title>

            <programlisting language="php"><![CDATA[
$input = 'to_RU';

    print "'{$input}' is a locale";
} else {
    print "Sorry... the given input is no locale";
}
]]></programlisting>
        </example>

        <para>
            As you can see, the output of this method is always a boolean. There is only one reason
            you could get an exception when calling this method. When your system does not provide
            any locale and Zend Framework is not able to detect it automatically. Normally this
            shows that there is a problem with your OS in combination with <acronym>PHP</acronym>'s
            <methodname>setlocale()</methodname>.
        </para>

        <para>
            You should also note that any given locale string will automatically be degraded if the
            region part does not exist for this locale. In our previous example the language
            <code>'to'</code> does not exist in the region <code>'RU'</code>, but you will still get
            <constant>TRUE</constant> returned as <classname>Zend_Locale</classname> can work with
            the given input.
        </para>

        <para>
            Still it's sometimes useful to prevent this automatic degrading, and this is where the
            second parameter of <methodname>isLocale()</methodname> comes in place. The
            <code>strict</code> parameter defaults to <constant>FALSE</constant> and can be used to
            prevent degrading when set to <constant>TRUE</constant>.
        </para>
