Question

PHP初学者在这里。寻找更高效的代码。

我有一个名为Brands的模型，我试图在视图中按字母顺序提取，排序和显示值。

例如：

品牌＆＃39;名称从字母A开始

Brand1
Brand2 .....等

品牌＆＃39;名称从字母K开始

Brand1
Brand2 .....等

我可以通过以下代码执行相同的操作：

$ brandsTable = TableRegistry :: get（＆＃39; Brands＆＃39;）;

    $brandA = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'A%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'a%');

    $brandK = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'K%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'k%');

    $brandS = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'S%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 's%');

    $brandT = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'T%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 't%');

    $brandN = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'N%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'n%');

    $brandH = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'H%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'h%');

    $brandM = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'M%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'm%');

    $brandY = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'Y%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'y%');

    $brandR = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'R%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'r%');

    $brandW = $brandsTable->find('all')->where([
        'deleted =' => 0
        ])-> andWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'W%'
        )-> orWhere(['brand_name_eng LIKE :key'
        ])->bind(':key', 'w%');

    $this->set('brandsA', $brandA);
    $this->set('brandsK', $brandK);
    $this->set('brandsS', $brandS);
    $this->set('brandsT', $brandT);
    $this->set('brandsN', $brandN);
    $this->set('brandsH', $brandH);
    $this->set('brandsM', $brandM);
    $this->set('brandsY', $brandY);
    $this->set('brandsR', $brandR);
    $this->set('brandsW', $brandW);

我认为不是多次调用模型/执行查询的最有效方法。尝试寻找有效的解决方案（哈希：提取/排序等）但无法获得正确的输出。非常感谢你的帮助。谢谢！

更新在ThinTank和ndm评论之后很抱歉没有提到，因为它是一个日本网站，我正在寻找区分大小写的品牌＆＃39;名称从

[A，E，I，O，U]，[K]，[S]，[T]，[N]，[H]，[M]，[Y]，[R]，[W]

分别。例如：我的品牌如下

adidas，Allison，Edox，Reebok，Tissot等

输出应为： 品牌＆＃39;名称从ア[A，E，I，O，U]开始：阿迪达斯佳佳 EDOX

品牌＆＃39;名称从ラ[R]开始：锐步

品牌＆＃39;名称从タ[T]开始：天梭 ......等等，

以下是分解它的一种方法：

$listBrandsLetter = array('A', 'K', 'S', 'T', 'N', 'H', 'M', 'Y', 'R', 'W');

$brandsTable = TableRegistry::get('Brands');

foreach($listBrandsLetter as $letter)
{
    $currentBrand = $brandsTable->find('all')->where([
                        'deleted =' => 0
                        ])-> andWhere(['brand_name_eng LIKE :key'
                        ])->bind(':key', $letter.'%'
                        )-> orWhere(['brand_name_eng LIKE :key'
                        ])->bind(':key', strtolower($letter).'%');

    $this->set('brands'.$letter, $currentBrand);
}

如果您的目标是减少因性能问题而导致的查询次数，那么请通知它。如果表现还可以，那么只考虑因素就足够了
