Increase maximum file upload size in WordPress

I’ve tried many methods to increase the max filesize but this is the only one that works for me:

1. Create a file called php.ini in your /wp-admin folder (or open it if already exists)
2. Add these lines:

   upload_max_filesize = 64M
   post_max_size = 64M

Here you can set your maximum file upload size (in the above example the limit is set to 64MB).
