 ### `has(key)`

-<p>The builtin function <code>has</code> returns whether the input object has the given key, or the input array has an element at the given index.</p>
 
-<p><code>has($key)</code> has the same effect as checking whether <code>$key</code> is a member of the array returned by <code>keys</code>, although <code>has</code> will be faster.</p>
+内置函数`has`返回输入的object是否含有给定的key,或者返回输入的数组是否在给定索引有元素。
 
+`has($key)`和检查$key是否在`keys`返回的数组里是一样的效果，
+只不过`has`比较快一点。
