getting last submit errors in PHP

Say I do something like this

$request->validate([
    'title' => 'required|unique:posts|max:255',
    'body' => 'required',
    'publish_at' => 'nullable|date',
]);

The input doesn't validate, then a redirect back to the page with the form happens.

If I want to get the list of errors in PHP code how would I do that?

you can display all validation errors by looping errors

<!-- /resources/views/post/create.blade.php -->
 
<h1>Create Post</h1>
 
@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
 
<!-- Create Post Form -->

Codes are copied from laravel documentation - https://laravel.com/docs/10.x/validation#quick-displaying-the-validation-errors

@AungHtetPaing__ I saw how to get errors in a template. I would like to get the errors in PHP.

@dougd_nc The validation and redirect back happen automatically.

When you say 'in php' I assume you mean in the controller?

If you manually create a validator https://laravel.com/docs/10.x/validation#manually-creating-validators you can test for errors at the end of validation and inspect the validator to see what went wrong.

to maybe clarify my question:

validator raises exception
Laravel redirects to previous page
I can get the form values in the PHP using old().

What is the specific code I can use in (any) PHP to get the errors from the validator
