It's easy to execute migration locally on XAMPP using cmd, but on server where you script is it's little bit harder.

I use Linux server with cPanel. I wanted to execute migration for yii2-user. This is how I did it.

This is how you do it. Put your file, for example: migration.php in your root folder:

Put this code inside:

<?php
$output = exec('yes | php yii migrate/up --migrationPath=@vendor/dektrium/yii2-user/migrations');
echo "<pre>$output</pre>";
?>

Let me explain what it does:

exec - executes shell command

php yii migrate/up - executes command for migration, see details here (http://www.yiiframework.com/doc-2.0/guide-db-migrations.html)

--migrationPath=@vendor/dektrium/yii2-user/migrations - this is migration path, where migrations files I want to execute are located.

| - pipe, connecting second command with first

yes - after command:

php yii migrate/up --migrationPath=@vendor/dektrium/yii2-user/migrations

is executed, it will ask you:

Apply the above migrations? (yes|no) [no]

But since you cannot confirm or reject because you are executing php file you put "yes" before that command and it knows that after executing main command it has to confirm. You can put "no" instead.

Before executing file on your server, do it locally on your laptop using XAMPP to test it and see output.

This is working

exec('yes | php yii migrate/up --migrationPath=@vendor/dektrium/yii2-user/migrations')

but I guess this would work also, I didn't test

exec('php yii migrate/up --migrationPath=@vendor/dektrium/yii2-user/migrations | yes')
