How to check if a record is found in Yii2?

Question

Yii

I make a selection of a non-existent record, the result is true because into the array is not empty, it contains other fields.
Next, you will be prompted to delete the entry.

$followRecord = Follow::find([
            'userId' => 111,
            'onUserId' => 777
])->one();

 if($followRecord)
              //Удаление

Answer 1

if ( !empty($followRecord) ) {
    // Удаление
}

Answer 2

If you have a "true result", then it means that the one() function found the same record. One() returns either an array of the found entry's attributes, or NULL (`null` will be returned
if the query results in nothing). So check your database query.
And yes, I usually check like this:

$followRecord = Follow::find(['userId' => 111, 'onUserId' => 777])->one();
if ($followRecord instanceof Follow) {
// запись найдена - удаляем ???
}

Answer 3

!== null in if.
