How to write PHP code in Laravel blade?

In Laravel Blade templates, you can use @php and @endphp directives to embed PHP code blocks into the template.

Here’s an example:

@php
    $name = 'Alice';
    $age = 25;
@endphp

<p>Hello, my name is {{ $name }}. I am {{ $age }} years old.</p>

Inside the @php block, you can use any PHP code you want, including control statements and functions.

@php
    $name = 'Alice';
    $age = 25;

    if ($age > 21) {
        $message = "You are old enough to drink!";
    } else {
        $message = "You are not old enough to drink.";
    }
@endphp

<p>{{ $message }}</p>

You can also use the @foreach directive inside a @php block:

@php
    $items = [1, 2, 3, 4, 5];
    $total = 0;
@endphp

@foreach ($items as $item)
    @php
        $total += $item;
    @endphp
@endforeach

<p>The total is {{ $total }}</p>

Note that you should use @php blocks sparingly, as they can make your templates harder to read and maintain. If possible, you should try to use Blade directives and Laravel’s built-in functions to achieve the desired result.
