有条件地从数组中删除一个元素 - Cakephp

Question

各位开发者大家好，

我有下一个查询，根据我所在的国家/地区，我需要从所选字段中删除一个我不需要的元素，因为在某些国家/地区的数据库中，该特定列（字段）不需要'存在。在其他国家/地区，查询必须保持原样。因此，查询将遵循以下结构：

  $options['joins'] = array(
    array(
        'table' => 'td_addresses',
        'alias' => 'Address',
        'type' => 'LEFT',
        'conditions' => array(
            'Doctor.id = Address.doctor_id'
        )
    ),
    array(
        'table' => 'td_doctors_products',
        'alias' => 'DoctorsProducts',
        'type' => 'LEFT',
        'conditions' => array(
            'Doctor.id = DoctorsProducts.id_doctor'
        )
    ),
    array(
        'table' => 'td_products',
        'alias' => 'Products',
        'type' => 'LEFT',
        'conditions' => array(
            'DoctorsProducts.id_product = Products.id'
        )
    ),
    array(
        'table' => 'td_addresses_agenda',
        'alias' => 'AddressesAgenda',
        'type' => 'LEFT',
        'conditions' => array(
            'AddressesAgenda.address_id = Address.id'
        )
    )
);

$options['conditions'] = array(
    'Doctor.email !=' => '',
    'Doctor.accepted_social_politics >=' => 0
);

$options['fields'] = array(
 'Doctor.id', 
 'Doctor.email', 
 'Doctor.name',
 'Doctor.surname', 
 'Doctor.created', 
 'Doctor.profileimg', 
 'Doctor.list_experiencia_professional',
 'Doctor.logros_academicos', 
 'Doctor.premios_reconocimientos',
 'Doctor.status', 
 'Doctor.type_doctor',
 'Doctor.sexo',
 'Doctor.accepted_politics_wallet',
 'Doctor.accepted_social_politics',
 'DoctorsProducts.id_product', 
 'Address.phone',
 'Address.info_consulta',
 'DoctorsProducts.status',
 'AddressesAgenda.address_id');

echo json_encode($options['fields']["Doctor.accepted_politics_wallet"]);
$latam = ['mx', 'co'];
if(in_array(PAIS, $latam)){
    // Remove the field of Doctor.accepted_politics_wallet from $options['fields']
}


$options['order'] = array('Doctor.id ASC');
$options['group'] = array('Doctor.email');
$doctors_csv = $this->Doctor->find('all', $options);

应用 array_splice 可行吗？

提前致谢

Answer 1

最简单的方法是 filter 数组：

$options['fields'] = array_filter($options['fields'], function ($option) {
    return $option !== 'Doctor.accepted_politics_wallet';
});

基本上，它returns数组中与您要消除的值不匹配的任何值。

Answer 2

实际上有很多方法可以使用现有的 php 数组函数来实现，例如 array_filter()、array_diff()、array_search() 等 array_search()

if (($key = array_search('Doctor.accepted_politics_wallet', $options['fields'])) !== false) {
    unset($options['fields'][$key]);
}
 print_r($options);
