PHP中将字符串作为数组值传递给接收数组的函数处理

我有一个称为validate()的方法,该方法接受数组作为参数.

例如.

$v->validate([
'username' => [$username, 'required'],
'email' => [$email, 'required'],
'password' => [$password, 'required'],
]);


所以我要做的是为此动态创建参数.虽然不知道正确的术语.例如！

$v->validate([
'username' => [$username, 'required'],
'email' => [$email, 'required'],
'password' => [$password, 'required'],
$validate_parameters
]);


像这样的东西,会有固定字段和其他动态字段将作为参数发送.它将翻译为：

$v->validate([
'username' => [$username, 'required'],
'email' => [$email, 'required'],
'password' => [$password, 'required'],
'dynamicfield_1' => ['value_1', 'rule_1'],
'dynamicfield_2' => ['value_2', 'rule_2'],
'dynamicfield_3' => ['value_3', 'rule_3'],
]);


这是我的方法.

public function validateDynamicFields($compressed_field, $rules) {
$parameters = '';
foreach ($compressed_field as $key => $value) {
// Well technically this will not work since it's not even an array or some sort.
$parameters .= $key => [$value, $rules];
// I even tried this and hope that it would work but it doesn't
// $parameters .= "'{$key}' => [{$value}, '{$rules}'],";
}
return $parameters;
}


问题是,如何为validate()方法动态创建数组值？

解决方法:

您可以使用array_merge：

$v->validate(array_merge(
[
'username' => [$username, 'required'],
'email' => [$email, 'required'],
'password' => [$password, 'required']
],
$validate_parameters
));
