Or alternatively, use autoload, which saves you having to specify it loads of times. I suspect the autoload functionality would be the best thing for you, assuming you're using a new-enough version of PHP (it requires 5.3). share|improve this answer answered Sep 22 '10 at 13:56 Spudley 117k28159241

Wesamazmy commented Oct 4, 2015 That is happen because this class declared at least 2 times, the first one in laravel/database/migrations/ , and the another one is declared in a non-explicit way by composer as you can see in (/vendor/composer/autoload_classmap.php). In order to handle this issue, first you have to run : $ composer install and not that the composer will generate warning look like this: Warning: Ambiguous class resolution, "CreateUsersTable" was found in both "/var/www/html/laravel1/database/migrations/2015_09_28_082513_create_users_table.php" and "/var/www/html/laravel2/database/migrations/2014_10_12_000000_create_users_table.php", the first will be used. This explains why the laravel migration return this collision warning. 👍 6 mkhuramj commented Mar 15, 2016 Thanks Wesamazmy!
