PHP 链式操作优雅的写法？

Question

在PHP中使用链式操作有优雅一点的写法吗？如果一个链式操作比较复杂，需要写很长一行，什么时候换行？
不换行：
functiontest(){
$res=$this->erp_base->select(['company_idAScity_id','city_nameAScity_name','UNIX_TIMESTAMP()AScreate_time','UNIX_TIMESTAMP()ASupdate_time'])->where(['if_deleted='=>0])->where_not_in('company_id',$this->_blacklist)->get('company')->result_array();
return$res;
}
数组换行：
functiontest(){
$res=$this->erp_base->select([
'company_idAScity_id',
'city_nameAScity_name',
'UNIX_TIMESTAMP()AScreate_time',
'UNIX_TIMESTAMP()ASupdate_time'
])->where([
'if_deleted='=>0
])->where_not_in('company_id',$this->_blacklist)->get('company')->result_array();
return$res;
}
我现在用的换行：
functiontest(){
$res=$this->erp_base
->select([
'company_idAScity_id',
'city_nameAScity_name',
'UNIX_TIMESTAMP()AScreate_time',
'UNIX_TIMESTAMP()ASupdate_time'
])->where([
'if_deleted='=>0
])->where_not_in('company_id',$this->_blacklist)
->get('company')
->result_array();
return$res;
}
或者这种：
functiontest(){
$res=$this->erp_base
->select([
'company_idAScity_id',
'city_nameAScity_name',
'UNIX_TIMESTAMP()AScreate_time',
'UNIX_TIMESTAMP()ASupdate_time'
])->where([
'if_deleted='=>0
])->where_not_in('company_id',$this->_blacklist)
->get('company')
->result_array();
return$res;
}
亦或者这种，和第一个换行的地方箭头保持一致（又时候对不齐）：
functiontest(){
$res=$this->erp_base
->select([
'company_idAScity_id',
'city_nameAScity_name',
'UNIX_TIMESTAMP()AScreate_time',
'UNIX_TIMESTAMP()ASupdate_time'
])->where([
'if_deleted='=>0
])->where_not_in('company_id',$this->_blacklist)
->get('company')
->result_array();
return$res;
}
处女座表示代码风格很重要。各位是怎么写的呢？
