PHP Syntax check not working - linter not working

Question

My php linter is not working from Atom or the Command line.

CMD: php -l <filename>

Result: No syntax errors detected in C:\example\path\file.php

---

Running:

• Windows 10
• php 7.3.11

---

Things already checked:

• yes, the file really exists
• liner is installed (version 2.3.1)
• linter-php is installed (version 1.6.1)
• other linters work fine
• path to php.exe is defined in the package and config.json

Answer 1

Solution short_open_tag=On in php.ini was set to Off needs to be On for linter to catch errors if you are using short tags <? vs <?php.

Hope this helps someone else.
