Laravel Blade Ternary Operator: Fixing Object Property Interpolation in Double-Quoted Strings

I'm experiencing an issue in my Laravel Blade template where a ternary operator used in a double-quoted string does not interpolate an object's property correctly. The intended behavior is to conditionally add attributes to an anchor tag if a mobile number exists, but PHP stops parsing the expression at the object accessor.
Here's the problematic code:
BLADE<a {{ $item->User->mobile ? "href=tel:$item->User->mobile class=underline" : "" }}>{{ $item->User->mobile ?? "" }}</a>
When checking the output in Chrome's Console, the anchor text is correct, yet the href attribute mistakenly includes only "$item->User" with the remaining "->mobile" appended as literal text. This indicates that PHP's interpolation does not automatically capture the full object property expression when using double quotes.
I've seen suggestions to wrap the property in curly braces for proper interpolation, like so:
BLADE<a {{ $item->User->mobile ? "href=tel:{$item->User->mobile} class=underline" : "" }}>{{ $item->User->mobile ?? "" }}</a>
Alternatively, some recommend using Blade's conditional attribute directives. What is the best practice to resolve this interpolation issue so that the entire expression is evaluated correctly?

The issue is that PHP’s double-quoted string interpolation doesn’t correctly parse object properties when you write them like this. In the string
PHP"href=tel:$item->User->mobile class=underline"
PHP sees the variable as "$item->User" and then the "->mobile" is left hanging. To fix this, you need to wrap the object property in curly braces so that PHP knows to include the entire expression. For example:
BLADE<a {{ $item->User->mobile ? "href=tel:{$item->User->mobile} class=underline" : "" }}>{{ $item->User->mobile ?? "" }}</a>
This tells PHP to properly interpolate the entire "$item->User->mobile" expression in the string.
Another alternative would be to conditionally add the attributes using Blade syntax like this:
BLADE<a @if($item->User->mobile) href="tel:{{ $item->User->mobile }}" class="underline" @endif> {{ $item->User->mobile ?? "" }} </a>
Both approaches resolve the issue.
