Use of undefined constant STDIN, fgets() issues running Drush.

[liquidcms]

I am posting just to see if anyone has seen these issues before:

Yesterday drush was running fine on our server. I suspect our hosting company modified something; most likely to do with PHP CLI. These are a few issues which i see now; which weren't there yesterday.

1. following commands all work: cron, cr, st but the output of all of them has this at the end:
   X-Powered-By: PHP/7.2.28
   Content-type: text/html; charset=UTF-8

2. drush updb fails:
   [warning] Use of undefined constant STDIN - assumed 'STDIN' (this will throw an Error in a future version of PHP) QuestionHelper.php:158
   [warning] fgets() expects parameter 1 to be resource, string given QuestionHelper.php:174

3. drush was (removed for bugfixes #1, Error using --no-core & --prepare-install #2 above) complaining about my local php.ini having:
   disable_functions = shell_exec,system

4. every drush command was failing due to a http to https chunk of code that i had in my settings.php (removed for bugfixes #1, Error using --no-core & --prepare-install #2 above).

These all worked yesterday.

Even more oddness.. when i called in to our hosting support; the guy there tried it and it worked fine. So it has something to do with ip, ssh client, session, etc. Although, I tried from a different IP with a different SSH client.. still broken.

Somehow you are using php-cgi instead of php-cli. Check your $PATH, which drush etc.

Hi Greg... and yes.. i just figured that partially out.. like 2 min ago.. on call with hosting company now to sort it out.. but thanks a ton.

Yes, path was wrong.. /usr/bin was ahead of /usr/local/bin which was putting php-fcgi ahead of php-cli

fixing that and it now runs without tacking:
X-Powered-By: PHP/7.2.28
Content-type: text/html; charset=UTF-8
at the end of every command.

And drush updb now runs correctly...

unfortunately cr, which did work when PATH was wrong.. now spits out:
[warning] Drush command terminated abnormally.

even though --vvv is no help; my guess is cli php.ini is now to blame and there is a memory issue.. but just a guess..

[liquidcms]

yes, tracking down cli php.ini and setting memory_limit = -1 fixed issue with cr.. and now all is well.
