If, in below function $query is null, this causes an error in php 8.0.0!

File: ParticipantAttributeName.php

public function editParticipantAttributeValue($data)
{
$query = ParticipantAttribute::model()
->find(
'participant_id = :participant_id AND attribute_id=:attribute_id',
array(':participant_id' => $data['participant_id'],
':attribute_id' => $data['attribute_id'])
);

    if (count($query) == 0) {
        Yii::app()->db->createCommand()
                    ->insert('{{participant_attribute}}', $data);
    } else {
        Yii::app()->db->createCommand()
            ->update(
                '{{participant_attribute}}',
                $data,
                'participant_id = :participant_id2 AND attribute_id = :attribute_id2',
                array(':participant_id2' => $data['participant_id'], ':attribute_id2' => $data['attribute_id'])
            );
    }
}

For reference:
https://www.php.net/manual/en/function.count.php
"
Returns the number of elements in value. Prior to PHP 8.0.0, if the parameter was neither an array nor an object that implements the Countable interface, 1 would be returned, unless value was null, in which case 0 would be returned.
"
php 8.0.0 count() will now throw TypeError on invalid countable types passed to the value parameter.
