How to convert to a one-dimensional array
This data is obtained using the select () method of thinkphp.
How can I convert it into a one-dimensional array?
Or can I use other TP methods to obtain a one-dimensional array without using the select () method when querying this data?

Take it directly

$data[0]

ThinkPhp method

->first();

But you can talk about your needs. for example, what you get is unique? Or is it just the first response to a pile of data?

Use the find method in the model

You can use foreach to traverse it.

Do not use the select statement of thinkphp. it is used to retrieve multiple records. PHP executes the statement online.

Select () to find ()
