How to know Laravel version and where is it defined?

run php artisan --version from your console.

The version string is defined here:

https://github.com/laravel/framework/blob/master/src/Illuminate/Foundation/Application.php

/**
 * The Laravel framework version.
 *
 * @var string
 */
 const VERSION = '5.5-dev';

---

  1)  php artisan -V

  2)  php artisan --version

AND its define at the composer.json file

"require": {
        ...........
        "laravel/framework": "^6.2",
        ...........
    },

---

If you want to know the specific version then you need to check composer.lock file and search For

"name": "laravel/framework",

you will find your version in next line

"version": "v5.7.9",

---

If you want to know the user version in your code, then you can use using app() helper function

app()->version();

It is defined in this file ../src/Illuminate/Foundation/Application.php

Hope it will help :)

Run this command in your project folder location in cmd

php artisan --version

---

Yet another way is to read the composer.json file, but it can end with wildcard character *

---

In your Laravel deployment it would be

/vendor/laravel/framework/src/Illuminate/Foundation/Application.php

to see who changed your Laravel version look at what's defined in composer.json. If you have "laravel/framework": "5.4.*", then it will update to the latest after composer update is run. Composer.lock is the file that results from running a composer update, so really see who last one to modify the composer.json file was (hopefully you have that in version control). You can read more about it here https://getcomposer.org/doc/01-basic-usage.md

---

You can also check with composer:

composer show laravel/framework

---

Multiple way we can find out laravel version such as,

Using Command

php artisan --version
  or
php artisan -v

From Composer.json

From Vendor Directory

/vendor/laravel/framework/src/Illuminate/Foundation/Application.php

---

If you're like me and want to show the Laravel version and app version on the footer you can create a Blade directive in AppServiceProvider. Blade directives are placed in the boot method of the AppServiceProvider and example code may like something like

Blade::directive('laravelVersion', function () {
    return "<?php echo app()->version(); ?>";
});

then in the blade template, you call it like @laravelVersion and it will show the current laravel version.

If you want, you can read more about blade directive here
