TP5 error reporting variable type error: array solution

When you are in tp5 When a method is written in the framework, an array is returned ,tp5 Will report a mistake ：variable type error： array

This is because tp5 Returning arrays is not supported .

I made it up 2 A solution , Everyone depends on their actual needs , To decide which method to use .

Method 1 ： Need to modify your source code

Add... Directly to the return statement json()、xml()..... Wait for the data type function you need to return

for example ：

<?phpnamespace app\index\controller;use think\Db;class Index{ public function index() { $returnData=json(Db::query('select * from xtable');) return $returnData; }}

Method 2 ： Do not modify the source code , Need to be revised tp5 The configuration file

Find and open tp5 In the framework “config.php” The configuration file . Find... In the configuration file

'default_return_type' => 'html'（ As shown in the figure below ）

Set this property to the data type you want to return . For example, it can be set to ：

'default_return_type' => 'json' perhaps 'default_return_type' => 'xml'

above 2 Both methods can return results , We decide which kind of... To use according to our actual needs .
