Why is php swearing?

Question

PHP

Gentlemen programmers, help if you can.
After an unexpected reboot, the site stopped loading - error 500.
In the logs -

[Thu Aug 04 11:34:01.363258 2016] [:error] [pid 2023] [client 192.168.0.92:51674] PHP Parse error: syntax error, unexpected '<<' (T_SL) in /var/www/mysql_connect. php line 3

And the same for other files and lines.
This line contains a construction like <<<<<<< HEAD
What is the problem?
The programmer claims that everything worked yesterday.

Answer 1

These are conflict artifacts in .git. Someone did not resolve the conflict and pushed everything into the master.
This, of course, should be fixed by the programmer.
