Access php variable defined in master blade in other blades where master blade is extended . PHP Lar-CodePudding

I am working on a laravel PHP project and I have a global blade where I have defined a variable

<?php
    $a = "some value fetched dynamically";
?>

And I am extending this blade in over 100 blade files like this

@extends('global')

In all these blades how can I access this $a variable?

Versions - PHP 7.2.34, Laravel 5.3.31

Thanks in advance.

PS: if there is any other way where I can get the PHP variable/function defined in the global blade in other blades please feel free to suggest.

CodePudding user response：

Choose blade or layout you are importing in every blade and add this code

// AppServiceProvider.php

public function register()
{
  // the layout you want, You can add '*' instead of 'blade' for all views
  \View::composer('blade', function ($view) {
     $value = "Data"
     $view->with('value', $value);
  });
}

At the blade use it like a normal variable.

Also, you can do it in another way Laravel composer
