PHP Notices, Warnings and Errors

[polanskiman]

These are some PHP warning/notices I have seen. Probably some not very important but I though I'd post them here for the record. It's just a selection as there is a load more notices but I suppose they are not important so I have only added a few.

System:
Synology Box running DSM 6.0.2 / Linux 3.2.40 #8451
COREbos 7
PHP Version 5.6.28


Errors below:

Code:

Deprecated: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in Unknown on line 0
