"For some reason, ""?"" is inserted at the beginning of the page with ""cakephp3""

If you look at the source display on the page, for some reason, the first html document (before the document tag) comes with a "?"The error page and the page you created are all the same.

↓Output source first line

?<!DOCTYPE html>

Could you tell me what you can think of?
I thought the BOM was garbled, so I checked that all the modified files were without BOM and uploaded them to FTP binary, but they still didn't work.

Environment
Sakura Internet
PHP 5.6
cakephp3

php cakephp

We have solved the problem by using Answer on the page of the person who asked the same question.

$findconfig-name"*.php" | xargs head-n1-q
$ find src-name "*.php" | xargs head-n 1-q

"When I searched with the above command, ""bootstrap"" was mixed with ""?", and I was able to delete it and solve it without any problems."

Thank you to everyone who commented.
