What causes PHP CLI to display nothing?

Question

PHP

PHP 5.6.30 is installed on CentOS 7, the sites work and everything seems to be fine, but php-cli does not work, more precisely, if you try to do something, it does not display anything, there are no results or errors either, it's just empty. What could be causing this problem?
Here's a script:

<?php
echo "Hello!";
?>

If you do this: php test.php > test.log will create an empty text.log
and if you just do php text.php nothing either

Answer 1

It most likely crashes before the start of any output, and all error output is disabled in php.ini.
Check: php script.php && echo ok
If "ok" doesn't appear in the console, it means that it really crashed.
The second option - somewhere die / exit crept in before the start of the output
