Judgment status value syntax under thinkphp

In the thinkphp framework we often use status value judgment: but writing this way will cause syntax errors.

<p>
    <if condition="{$res.status} eq &#39;0&#39;">测试</if></p>

2. Correct writing: Because the "." syntax cannot be used in thinkphp

<if condition="$res[&#39;status&#39;] eq 0">测试</if>

The

f tag already contains PHP parsing. If you write {} tag parsing in it, an error that does not conform to PHP syntax will be reported.
