对于返回数据格式，有返回json的，也有返回array的。而查询的结果是集合对象，本篇文章对查询结果集合进行转换。

序列化为数组

toArray将模型结果转为数组

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">use</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">App\Models\User</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">User</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">first</span>()<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">toArray</span>();</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">dd</span>(<span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span>);</span>

attributesToArray将模型属性转为数组

$user = User::first()->attributesToArray();

序列化JSON

toJson方法将结果转为JSON

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 85, 170)">$posts</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">Post</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">find</span>(<span style="box-sizing: border-box;color: rgb(17, 102, 68)">1</span>)</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">return</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$posts</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">toJson</span>();</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">return</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$posts</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">toJson</span>(<span style="box-sizing: border-box;color: rgb(0, 0, 0)">JSON_PRETTY_PRINT</span>);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 除了上述2种，可以将结果用字符串返回</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">return</span> (<span style="box-sizing: border-box;color: rgb(0, 0, 0)">string</span>)<span style="box-sizing: border-box;color: rgb(0, 85, 170)">$posts</span>;</span>

转JSON/ARRAY时隐藏属性

转化数据为JSON或ARRAY时，如要隐藏密码等重要属性时，可以在模型中使用$hidden属性。

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// app/Models/User.php</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">protected</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$hidden</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> [<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'password'</span>];</span>

转化数据

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">User</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">find</span>(<span style="box-sizing: border-box;color: rgb(17, 102, 68)">1</span>);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 打印结果就看不到password了</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">dd</span>(<span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">toArray</span>());</span>

makeVisible()临时显示隐藏属性

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">User</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">find</span>(<span style="box-sizing: border-box;color: rgb(17, 102, 68)">1</span>);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">dd</span>(<span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">makeVisible</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'password'</span>)<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">toArray</span>());</span>

makeHidden隐藏某个属性

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">User</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">find</span>(<span style="box-sizing: border-box;color: rgb(17, 102, 68)">1</span>);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">dd</span>(<span style="box-sizing: border-box;color: rgb(0, 85, 170)">$user</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">makeHidden</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'id'</span>)<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">toArray</span>());</span>
