Why does this Blade component not receive a parameter?-CodePudding

I am using Laravel 9 and trying to understand the components.

I have this 'anonymous' component (extract) :

<option value="{{ $phase->id }}" @if(isset($phase_id) && $phase_id===$phase->id) selected @endif>
        {{ $phase->name }}
    </option>

The component is called like that :

 <x-select-phase id="phase_id" name="phase_id" :phase_id="$event->phase_id"

I am expecting that the var $phase_id exists inside the component. It is not the case, and do not understand why. I tried a lot of things without success. What can I try next?

Component constructor arguments should be specified using camelCase, while kebab-case should be used when referencing the argument names in your HTML attributes.

This means:

:phase-id="$event->phase_id"

should generate a variable:

$phaseId
