Php code cannot be read when run on localhost

[lollipop]

hi, i am Hamdi. I’m still a beginner using Linux. and manjaro was my first linux. i have problems running php.
i tried to run my php code in localhost/test.php.
The test.php file contains commands such as “echo” and so on.
but when I try to run localhost/test.php, the result that appears is a blank page.
it seems my php code is not readable.
.
even though I have installed PHP, Apache and MariaDB.
I checked the status of Apache and MariaDB and it was running and there were no problems.
I checked the error log in “/var/log/httpd/error_log”
but I didn’t find the error.
.
I tried checking the configuration using sudo apachectl configtest
the result is that the syntax is okay.
there are no errors either.
.
I tried opening the apache configuration in httpf.conf using the command sudo nano /etc/httpd/conf/httpd.conf.
then I tried changing LoadModule mpm_event to #LoadModule mpm_event.
while #LoadModule mpm_prefork becomes LoadModule mpm_prefork.
then I saved and tried restarting apache again.
and I checked the status and it was active.
then I tried again to run localhost/test.php
but the result is that the page is still blank.
my php code is still unreadable.
while the HTML and CSS code can still be read.
.
Please help me.

thank you for your answers. that’s very helpful.
I’ve tried it and it works.
However, that only applies to newly created PHP code files.
whereas when I tried the php code file that I took from GitHub. and just run it on localhost/ . the page returns blank. php code is not readable, problem as before.

Manjaro forum is not a support forum for someone getting their feets wet in some programming language neither a support forum for random code found on github nor anywhere else.

There is plenty fora around the interweb which has specialized in various languages.

That said - if you could make the info.php from the above topic work then php works - it is probably your lack of knowledge which is in play here.

There is only one thing you can do, search, read and learn.

Place the php file in /srv/http and point the browser to ip.x.y.z/test.php - then it may work or it may not - that depends on the code in question - and please - don’t ask why here - ask the author of said code, please?
