    <title>Basic Usage</title>

    <para>
        Usage of <classname>Zend_Json</classname> involves using the two public static
        methods available: <methodname>Zend_Json::encode()</methodname> and
        <methodname>Zend_Json::decode()</methodname>.
    </para>

    <programlisting language="php"><![CDATA[
// Retrieve a value:
$phpNative = Zend_Json::decode($encodedValue);

// Encode it to return to the client:
$json = Zend_Json::encode($phpNative);
]]></programlisting>

    <sect2 id="zend.json.basics.prettyprint">
        <title>Pretty-printing JSON</title>

        <para>
            Sometimes, it may be hard to explore <acronym>JSON</acronym> data generated by
            <methodname>Zend_Json::encode()</methodname>,
            since it has no spacing or indentation. In order to make it easier, <classname>Zend_Json</classname>
            allows you to pretty-print <acronym>JSON</acronym> data in the human-readable format
            with <methodname>Zend_Json::prettyPrint()</methodname>.
        </para>

        <programlisting language="php"><![CDATA[
// Encode it to return to the client:
$json = Zend_Json::encode($phpNative);
if($debug) {
    echo Zend_Json::prettyPrint($json, array("indent" => " "));
}
]]></programlisting>

        <para>
            Second optional argument of <methodname>Zend_Json::prettyPrint()</methodname> is an option array.
            Option <code>indent</code> allows to set indentation string - by default it's a single tab character.
