link : link.
link : link.
The above two links are official for find and select Interpretation of , If you are interested, you can click in to have a look .

I personally agree with one of them ：find() Returns a one-dimensional array ,select() Returns a two-dimensional array , So the values are different , One dimensional array value with $data["n"],TwodimensionCountGrouptakevalueuse$data[0][“n”];

find What we found is a record ,select We found multiple records .
In turn to , Check a record find, For checking multiple records select .

If these two are used incorrectly , Data will not come out , There is no display on the page .

Here are some Inline code slice .

// An highlighted block
 When the view is displayed , use find  The result of the search is assigned to the variable if $res, Then the view shows {
    $res}
 and select  The result of the search is assigned to the variable if $result, Then general and foreach,volist These are used in combination .name="result",foreach after , View presentation {
    $v. Field name }
