linux php with apache and html on armv7

I installed apache and php on a armv7 board. I wanna use apache to run php scripts. I made a simple script in php to run and depending on how i debug the script in console i got different outputs. I I run: php-cgi test.php i got this output:

X-Powered-By: PHP/8.2.8
Content-type: text/html; charset=UTF-8

1

instead if I run: php test.php I only got:

1

How can I know which php is running apache? Im asking because easch time I tried to run the script throwgh html i got "empty string". It seems like is not getting this "1". I tried to remove this X-Powered and Content-type by modifying php.ini but Im still getting this weird char ^M and don't know where to remove this char. Is there a way I can setup apache to run only php and not run php-cgi? Is there a way i can test what appache is getting running this apache script? Could this be something related to POST apache php? Gastón

I alredy tried runing script with: #!/usr/bin/php I check that running from terminal php-cgi -q test.php I only got the "1" like running php test.php I modified php.ini to remove Content-type and Xpowered but getting this weird ^M that I tried to remove by remove_header in php script.
