7.x ヘルパ Laravel

イントロダクションIntroduction

Laravelはさまざまな、グローバル「ヘルパ」PHP関数を用意しています。これらの多くはフレームワーク自身で使用されています。便利なものが見つかれば、皆さんのアプリケーションでも大いに活用してください。Laravel includes a variety of global "helper" PHP functions. Many of these functions are used by the framework itself; however, you are free to use them in your own applications if you find them convenient.

All exceptions that are caught will be sent to your exception handler[/docs/{{version}}/errors#the-exception-handler]'s report method; however, the request will continue processing:

return rescue(function () {
    return $this->method();
});

rescue関数には第2引数を渡すことができます。クロージャ実行時に例外が発生した場合、第2引数に渡した値が返されるデフォルトの値になります。You may also pass a second argument to the rescue function. This argument will be the "default" value that should be returned if an exception occurs while executing the Closure:

return response('Hello World', 200, $headers);

return response()->json(['foo' => 'bar'], 200, $headers);

`retry()` {#collection-method}`retry()` {#collection-method}

retry関数は指定された最大試行回数を過ぎるまで、指定されたコールバックを実行します。コールバックが例外を投げなければ、返却値が返されます。コールバックが例外を投げた場合は、自動的にリトライされます。最大試行回数を超えると、例外が投げられます。The retry function attempts to execute the given callback until the given maximum attempt threshold is met. If the callback does not throw an exception, its return value will be returned. If the callback throws an exception, it will automatically be retried. If the maximum attempt count is exceeded, the exception will be thrown:

return retry(5, function () {
    // 実行間で500ms空け、５回試行する
}, 100);

`session()` {#collection-method}`session()` {#collection-method}

`tap()` {#collection-method}`tap()` {#collection-method}

tap関数は引数を２つ取ります。アビリティの$valueとクロージャです。$valueはクロージャに渡され、それからtap関数により返されます。クロージャから返す値は無視されます。The tap function accepts two arguments: an arbitrary $value and a Closure. The $value will be passed to the Closure and then be returned by the tap function. The return value of the Closure is irrelevant:

$user = tap(User::first(), function ($user) {
    $user->name = 'taylor';

    $user->save();
});

tap関数でクロージャを指定しない場合、渡した$valueのメソッドを呼び出せます。メソッド呼び出しの戻り値は常に$valueになり、メソッドが実際に返す値とは無関係です。たとえば、Eloquentのupdateメソッドは、通常整数値を返します。しかし、updateメソッドをtap関数にチェーンして呼び出すことで、メソッドにモデル自身を返すように強制できます。If no Closure is passed to the tap function, you may call any method on the given $value. The return value of the method you call will always be $value, regardless of what the method actually returns in its definition. For example, the Eloquent update method typically returns an integer. However, we can force the method to return the model itself by chaining the update method call through the tap function:

$user = tap($user)->update([
    'name' => $name,
    'email' => $email,
]);

クラスへtapメソッドを追加するには、Illuminate\Support\Traits\Tappableトレイトをそのクラスへ追加してください。このトレイトのtapメソッドはクロージャだけを引数に受け取ります。オブジェクトインスタンス自身がクロージャに渡され、tapメソッドによりリターンされます。To add a tap method to a class, you may add the Illuminate\Support\Traits\Tappable trait to the class. The tap method of this trait accepts a Closure as its only argument. The object instance itself will be passed to the Closure and then be returned by the tap method:

return $user->tap(function ($user) {
    //
});

`throw_if()` {#collection-method}`throw_if()` {#collection-method}

throw_if関数は、指定した論理式がtrueと評価された場合に、指定した例外を投げます。The throw_if function throws the given exception if a given boolean expression evaluates to true:

throw_if(! Auth::user()->isAdmin(), AuthorizationException::class);

throw_if(
    ! Auth::user()->isAdmin(),
    AuthorizationException::class,
    'You are not allowed to access this page'
);

`throw_unless()` {#collection-method}`throw_unless()` {#collection-method}

throw_unless関数は、指定した論理式がfalseと評価された場合に、指定した例外を投げます。The throw_unless function throws the given exception if a given boolean expression evaluates to false:

throw_unless(Auth::user()->isAdmin(), AuthorizationException::class);

throw_unless(
    Auth::user()->isAdmin(),
    AuthorizationException::class,
    'You are not allowed to access this page'
);

`today()` {#collection-method}`today()` {#collection-method}

today関数は、現在の日付を表す新しいIlluminate\Support\Carbonインスタンスを生成します。The today function creates a new Illuminate\Support\Carbon instance for the current date:

$today = today();

`trait_uses_recursive()` {#collection-method}`trait_uses_recursive()` {#collection-method}

trait_uses_recursive関数は、そのトレイトで使用されている全トレイトを返します。The trait_uses_recursive function returns all traits used by a trait:

$traits = trait_uses_recursive(\Illuminate\Notifications\Notifiable::class);

`transform()` {#collection-method}`transform()` {#collection-method}

transform関数は、指定値がblankでない場合に指定値を「クロージャ」で実行し、実行結果を返します。The transform function executes a Closure on a given value if the value is not blank[#method-blank] and returns the result of the Closure:

$callback = function ($value) {
    return $value * 2;
};

$result = transform(5, $callback);

// 10

デフォルト値か「クロージャ」を第３引数として渡すこともできます。この値は指定値がblankの場合に返されます。A default value or Closure may also be passed as the third parameter to the method. This value will be returned if the given value is blank:

$result = transform(null, $callback, 'The value is blank');

// The value is blank

`validator()` {#collection-method}`validator()` {#collection-method}

validator関数は、指定した引数で新しいバリデータインスタンスを生成します。利便のため、Validatorファサードを代わりに使うこともできます。The validator function creates a new validator[/docs/{{version}}/validation] instance with the given arguments. You may use it instead of the Validator facade for convenience:

$validator = validator($data, $rules, $messages);

`value()` {#collection-method}`value()` {#collection-method}

value関数は指定値を返します。「クロージャ」を関数に渡した場合は実行し、結果を返します。The value function returns the value it is given. However, if you pass a Closure to the function, the Closure will be executed then its result will be returned:

$result = value(true);

// true

$result = value(function () {
    return false;
});

// false

`view()` {#collection-method}`view()` {#collection-method}

view関数はviewインスタンスを返します。The view function retrieves a view[/docs/{{version}}/views] instance:

return view('auth.login');

`with()` {#collection-method}`with()` {#collection-method}

with関数は指定値を返します。「クロージャ」を第２引数へ渡した場合は実行し、その結果を返します。The with function returns the value it is given. If a Closure is passed as the second argument to the function, the Closure will be executed and its result will be returned:

$callback = function ($value) {
    return (is_numeric($value)) ? $value * 2 : 0;
};

$result = with(5, $callback);

// 10

$result = with(null, $callback);

// 0

$result = with(5, null);

// 5
