Comment 0 for bug 1572841

always_populate_raw_post_data was deprecated in PHP 5.3 at which time zabbix frontend setup began to insist that it be set to always_populate_raw_post_data = -1 in the PHP.ini

In PHP 7.0, which Ubuntu 16.04 LTS ships with, always_populate_raw_post_data has been removed completely. Due to this PHP frontend setup gets stuck on always_populate_raw_post_data not being disabled.

The solution is to apply the following patch to the PHP frontend code to ignore PHP 7.0:
