Ten recommended Laravel helper functions

array_dot()

function allows you to convert a multidimensional array into a one-dimensional array using dot notation.

$array = [
    'user' => ['username' => 'something'],
    'app' => ['creator' => ['name' => 'someone'], 'created' => 'today']
];
$dot_array = array_dot($array);
// [user.username] => something, [app.creator.name] => someone, [app.created] => today

array_get()

Function retrieves values ​​from a multidimensional array using dot notation.

$array = [
    'user' => ['username' => 'something'],
    'app' => ['creator' => ['name' => 'someone'], 'created' => 'today']
];
$name = array_get($array, 'app.creator.name');
// someone

The array_get() function also accepts an optional third parameter as a default value if key does not exist.

$name = array_get($array, 'app.created.name', 'anonymous');
// anonymous

public_path()

Returns the fully qualified absolute path to the public directory in your Laravel application. You can also pass the path to a file or directory in the public directory to get the absolute path to the resource. It will simply add public_path() to your parameters.

$public_path = public_path();
$path = public_path('js/app.js');

Str::orderedUuid()

(1) The function first generates a timestamp uuid. This uuid can be stored in an indexed database column. These uuids are created based on timestamps, so they keep your content indexed;
(2) When using this in Laravel 5.6, a Ramsey\Uuid\Exception\UnsatisfiedDependencyException is thrown. To resolve this issue, just run the following command to use the moontoast/math package
composer require laravel/passport=~7.0

use Illuminate\Support\Str;
return (string) Str::orderByUuid()
// A timestamp first uuid

str_plural()

Convert a string to plural form. This feature only supports English.

echo str_plural('bank');
// banks
echo str_plural('developer');
// developers

route()

Generate the route URL for the specified route.

$url = route('login');
// 如果路由接受参数，你可以简单地将它们作为第二个参数传递给一个数组。
$url = route('products', ['id' => 1]);
// 如果你想产生一个相对的 URL 而不是一个绝对的 URL，你可以传递 false 作为第三个参数。
$url = route('products', ['id' => 1], false);

#tap()

Accepts two parameters: a value and a closure. The value will be passed to the closure and the value will be returned. The closure return value doesn't matter.

$user = App\User::find(1);

return tap($user, function($user) {
    $user->update([
        'name' => 'Random'
    ]);
});
/**
  * 它不会返回布尔值，而是返回 User Model 。如果你没有传递闭包，你也可以使用 User Model 的任何方法。
  * 无论实际返回的方法如何，返回值都将始终为值。 在下面的例子中，它将返回 User Model 而不是布尔值。
  * update 方法返回布尔值，但由于用了 tap ，所以它将返回 User Model。
  */ 
$user = App\User::find(1);

return tap($user)->update([
    'name' => 'SomeName'
]);

dump()
