How to echo to console in Laravel and Artisan?

Question

I was curious, I\'m using Laravel and Artisan for my migrations. Is there a method to output information to the console? I can\'t seem to find any information on this. For examp

Answer 1

Don't know if you are using Laravel 3 or Laravel 4, and if its also possible in Laravel 3, but i found this in the docs.

$this->info('Creating sample users...');

EDIT

If you switch to database seeds you can use this to display a message

$this->command->info('Creating sample users...');

Answer 2

Since the chosen answer doesn't seem to work since 4.2, I say just keep it simple:

public function up() {
     // Migration runs //
     echo 'Records processed' . PHP_EOL;
}

Answer 3

I like the color added by the Dumper (tested on Laravel 5.3). I think looks a bit nicer than using the echo. The issue I have with the echo out is that it's too easy to be missed, the Dumper it adds a bit of green which catches ones eye:

public function up() {
     // Migration runs //
     (new Illuminate\Support\Debug\Dumper)->dump("A bit more colorful text");
}

Answer 4

'Symfony\Component\Console\Output\ConsoleOutput;' works for me on Laravel 5.2

Answer 5

Talking about Laravel 5 (you can check the version you have with php artisan --version), the Migration base-class has no printing method.

A simple echo will do the work, However, if you want, you can extend it and add this functionality:

abstract class MyMigration extends Migration
{
    // colors for console echo
    protected const COLOR_RED = 'COLOR_RED';
    protected const COLOR_GREEN = 'COLOR_GREEN';
    protected const COLOR_YELLOW = 'COLOR_YELLOW';

    protected function logMessage($str, String $color = null)
    {
        switch ($color) {
            case self::COLOR_RED:
                $str = "\033[01;31m$str\033[0m";
                break;
            case self::COLOR_GREEN:
                $str = "\033[01;32m$str\033[0m";
                break;
            case self::COLOR_YELLOW:
                $str = "\033[01;33m$str\033[0m";
            break;

            echo $str . PHP_EOL;
        }
    }
}

and then simply call it with your message:

$this->logMessage("Your message", self::COLOR_RED );

Answer 6

For database seeding in Laravel5, you can use

$this->command->getOutput()->writeln("<info>Your message here</info>");

to print the output on command line.

<info> shows the message in green color where as <error> shows in red color which can be used for error messages.
