php not interpretated

English Programming/Scripting
#1

Hi everybody.

I never have had any problem while setting Apache with PHP under Suse. Only recently with 10.3 and 11.0 I have a strange issue. Everything seems fine, php lib is correctly loaded by Apache, but when I try to open a page, php code is visible in the “View/Page Source” of Firefox and not executed.

I’m not able to find the reason. Any idea?

Thanks
Filippo

Check your Apache log files (/var/log/apache2 probably holds them).
Make sure Apache is also configured so that ‘*.php’ files are
interpreted by PHP and not just sent out directly. Of course I assume
your file ends in ‘.php’. There is also, I believe, a command you can
issue to show Apache’s loaded modules, but I can’t remember it right
now. You mentioned you believe it is loaded… what leads you to
believe that?

Good luck.

One reason is because Apache has not been configurated with the php5 module. You can check what modules are installated with:

/usr/sbin/a2enmod - l

See that php5 is in there. If not:

/usr/sbin/a2enmod php5

as root, of course, then restart apache.

Another reason is you are using short tags <? ?>. You should be using <?php ?> now.

Right. The problem was in short tags. Setting On to short_open_tag in php.ini it works.

I guess that some version ago this switch was On as default, actually it is Off. Any reason why the programmers are pushing to use <?php ?> now?

I checked the loaded modules through Yast/http server.

Thanks to all.

Three reasons are suggested in Coding Rules - ClaroDevel

  • Compatibility with xml files (xhtml, rss, …) where <?xml is used
  • Compatibility with 100% of php server where “short_open_tags” is off
  • “short_open_tags on” will be deprecated in PHP 6

Might as well get used to it.
