PHP 鏈?zhǔn)讲僮鲀?yōu)雅的寫法？

在 PHP 中使用鏈?zhǔn)讲僮饔袃?yōu)雅一點(diǎn)的寫法嗎？
如果一個鏈?zhǔn)讲僮鞅容^復(fù)雜，需要寫很長一行，什么時候換行？

不換行：

function test(){

    $res = $this->erp_base->select([ 'company_id AS city_id', 'city_name AS city_name', 'UNIX_TIMESTAMP() AS create_time', 'UNIX_TIMESTAMP() AS update_time' ]) ->where([ 'if_deleted =' => 0 ])->where_not_in('company_id', $this->_blacklist)->get('company')->result_array();
    
    return $res;
}

數(shù)組換行：

function test(){

    $res = $this->erp_base->select([
            'company_id AS city_id',
            'city_name AS city_name',
            'UNIX_TIMESTAMP() AS create_time',
            'UNIX_TIMESTAMP() AS update_time'
        ]) ->where([
            'if_deleted =' => 0
        ])->where_not_in('company_id', $this->_blacklist)->get('company')->result_array();
    
    return $res;
}

我現(xiàn)在用的換行：

function test(){

    $res = $this->erp_base
        ->select([
            'company_id AS city_id',
            'city_name AS city_name',
            'UNIX_TIMESTAMP() AS create_time',
            'UNIX_TIMESTAMP() AS update_time'
        ])->where([
            'if_deleted =' => 0
        ])->where_not_in('company_id', $this->_blacklist)
        ->get('company')
        ->result_array();
    
    return $res;
}

或者這種：

function test(){

    $res = $this->erp_base
    ->select([
        'company_id AS city_id',
        'city_name AS city_name',
        'UNIX_TIMESTAMP() AS create_time',
        'UNIX_TIMESTAMP() AS update_time'
    ])->where([
        'if_deleted =' => 0
    ])->where_not_in('company_id', $this->_blacklist)
    ->get('company')
    ->result_array();
    
    return $res;
}

亦或者這種，和第一個換行的地方箭頭保持一致（又時候?qū)Σ积R）：

function test(){

    $res = $this->erp_base
                ->select([
                    'company_id AS city_id',
                    'city_name AS city_name',
                    'UNIX_TIMESTAMP() AS create_time',
                    'UNIX_TIMESTAMP() AS update_time'
                ])->where([
                    'if_deleted =' => 0
                ])->where_not_in('company_id', $this->_blacklist)
                ->get('company')
                ->result_array();
                
    return $res;
}

處女座表示代碼風(fēng)格很重要。各位是怎么寫的呢？
