Error binding parameters in MatchExpression

[evgen84]

What steps will reproduce the problem?

The problem appears only in case parameter contains \ as last symbol. Seems it's in the
yii\sphinx\MatchBuilder::parseParams(). When changing preg_replace() to str_replace() it works but it seems it's not correct to use str_replace() based on comment:

// $model extends \yii\sphinx\ActiveRecord
$value = '543524\\';
$data = $model::find()
        ->match(new MatchExpression(['title' => $value]))
        ->all();

What's expected?

What do you get instead?

Exception 'yii\db\Exception' with message 'SQLSTATE[42000]: Syntax error or access violation: ...unexpected $end near
