PHP Laravel 将数组值转换为大写

Question

我的 Laravel 项目中有一个包含多个值的数组:

array:1434 [▼
  0 => array:53 [▼
    "contact" => "ANA (dependienta)"
    "mail" => "example@mail.com"
    "phone2" => ""
    "phone3" => ""
    "web" => "0"
    "active" => true
    "province" => "Zaragoza"

  ]
  1 => array:53 [▼
    "contact" => "JACKELINE * VIVIANA"
    "mail" => "mail@example.com"
    "phone2" => ""
    "phone3" => ""
    "web" => "0"
    "active" => true
    "province" => "Barcelona"

  ]

我只想将省值转换为大写，我想得到这个结果:

array:1434 [▼
  0 => array:53 [▼
    "contact" => "ANA (dependienta)"
    "mail" => "example@mail.com"
    "phone2" => ""
    "phone3" => ""
    "web" => "0"
    "active" => true
    "province" => "ZARAGOZA"

  ]
  1 => array:53 [▼
    "contact" => "JACKELINE * VIVIANA"
    "mail" => "mail@example.com"
    "phone2" => ""
    "phone3" => ""
    "web" => "0"
    "active" => true
    "province" => "BARCELONA"

  ]

是否存在使用 Laravel Collection 或其他替代方案来实现此目的的任何方法或方式？

Answer 1

如果您使用 Eloquent 从数据库获取数据，您可以 create an accessor

public function getProvince($value)
{
    return strtoupper($value);
}

如果没有，您可以手动更改它:

for ($i = 0; $i < count($data); $i++) {
    $data[$i]['province'] = strtoupper($data[$i]['province']);
}
