Answer 1

根据此博客文章“Solving the Doctrine Parenthesis Problem”，您需要执行$query->where("(ConditionA OR ConditionB) AND ConditionC");

这可能看起来像：

Doctrine_Query::create()
    ->from(...)
    ->where('A = ? OR B = ?', array(valA, valB))
    ->andWhere('C = ?', valC);

然而，通过扩展whereParenWrap()，海报确实提供了更通用的解决方案Doctrine_Query：

DQ::create()
->from(...)
->where('A = ?', valA)
->orWhere('B = ?', valB)
->whereParenWrap()
->andWhere('C = ?', valC);

Addon的答案：Brackets in Doctrine query

/*
 * This is a simple short-hand wrapper for Doctrine_Query. It provides
 * a shorter class name and a few additional functions.
 */
class DQ extends Doctrine_Query
{
    /**
     * Returns a DQ object to get started
     *
     * @return DQ
     */
    public static function create($conn = null, $class = null) {
        return new DQ($conn, $class);
    }

    /**
     * This function will wrap the current dql where statement
     * in parenthesis. This allows more complex dql statements
     * It can be called multiple times during the creation of the dql
     * where clause.
     *
     * @return $this
     */
    public function whereParenWrap() {
        $where = $this->_dqlParts['where'];
        if (count($where) > 0) {
            array_unshift($where, '(');
            array_push($where, ')');
            $this->_dqlParts['where'] = $where;
        }

        return $this;
    }
}

现在您可以使用Expr :: orX（）

        /** To combine all the OR conditions in one parenthesis, we will collect the conditions in one array */
        $orX = [];
        foreach ($dto->userNameSearchPhrases as $key => $userNameSearchPhrase) {
            $orX[] = $qb->expr()->like('us.username', ':userNameSearchPhrase' . $key);
            $qb->setParameter('userNameSearchPhrase' . $key, $userNameSearchPhrase);
        }
        /** To pass parameters to the Expr::orX() method from an array, use ReflectionMethod */
        $reflectionMethod = new \ReflectionMethod(\Doctrine\ORM\Query\Expr::class, 'orX');
        $orXObject = $reflectionMethod->invokeArgs($qb->expr(), $orX);
        $qb->andWhere($orXObject);
