I am looking for a reason why in blade files (Laravel) code with mixed @php() and @php ... @endphp fails, and works fine with consistent usage of those codes across the file. I’ve just learned that the hard way but can’t find the reason.

Fails:

@php($foo = 'foo')
<h1>{{ $foo }}</h1>
@php
    $bar = $foo . 'bar';
@endphp
@for($i = 1; $i<10; $i++)
    <h2><b>{{ $i }}<b/>{{ $bar }}</h2>
@endfor

Works fine:

@php($foo = 'foo')
<h1>{{ $foo }}</h1>
@php($bar = $foo . 'bar');
@for($i = 1; $i<10; $i++)
    <h2><b>{{ $i }}<b/>{{ $bar }}</h2>
@endfor

Also works fine:

@php
    $foo = 'foo';
@endphp
<h1>{{ $foo }}</h1>
@php
    $bar = $foo . 'bar';
@endphp
@for($i = 1; $i<10; $i++)
    <h2><b>{{ $i }}<b/>{{ $bar }}</h2>
@endfor

An error
