我正在使用 Laravel 5。我想知道哪些是传递给 View 本身的 View 的所有变量。
由于所有变量都在 View 范围内，我想我可以使用通用 PHP 函数:get_defined_vars(); http://php.net/manual/en/function.get-defined-vars.php
类似这样的:
// resources/view/home.blade.php
<html>
<body>
<?php print_r(get_defined_vars()); ?>
</body>
</html>
但我想知道是否有更好的方法(例如 View::getData())
注意: get_defined_vars() 不起作用，因为它返回数百个无用的变量(Laravel 组件)
这是一个使用 print_r(get_defined_vars()) 的片段(部分)(我认为它进入了无限递归循环):
Array
(
[__path] => C:\net\laravel\storage\framework\views/8e030a77b0bdbacc2c4182fc04420d1d
[__data] => Array
(
[__env] => Illuminate\View\Factory Object
(
[engines:protected] => Illuminate\View\Engines\EngineResolver Object
(
[resolvers:protected] => Array
(
[php] => Closure Object
(
[this] => Illuminate\View\ViewServiceProvider Object
(
[app:protected] => Illuminate\Foundation\Application Object
(
[basePath:protected] => C:\net\laravel
[hasBeenBootstrapped:protected] => 1
[booted:protected] => 1
[bootingCallbacks:protected] => Array
(
[0] => Closure Object
(
[static] => Array
(
[instance] => Illuminate\Bus\BusServiceProvider Object
(
[defer:protected] => 1
[app:protected] => Illuminate\Foundation\Application Object
*RECURSION*
)
)
[this] => Illuminate\Foundation\Application Object
*RECURSION*
)
[1] => Closure Object
(
[static] => Array
(
[instance] => Illuminate\Translation\TranslationServiceProvider Object
(
[defer:protected] => 1
[app:protected] => Illuminate\Foundation\Application Object
*RECURSION*
)
)
[this] => Illuminate\Foundation\Application Object
*RECURSION*
)
)
[bootedCallbacks:protected] => Array
(
)
[terminatingCallbacks:protected] => Array
(
)
[serviceProviders:protected] => Array
(
[0] => Illuminate\Events\EventServiceProvider Object
(
[app:protected] => Illuminate\Foundation\Application Object
*RECURSION*
[defer:protected] =>
)
最佳答案
使用 dd 助手:
{{ dd(get_defined_vars()) }}

更新(thx，@JoeCoder):您可以通过以下方式进一步减少“无用”变量:
{{ dd(get_defined_vars()['__data']) }}
