An unknown PHP error occurred

[Karl Stenerud]

I've installed virtualbox, phpvirtualbox, php5-fpm, and nginx. When I
browse to phpvirtualbox, I get the following:

An unknown PHP error occurred. This is most likely a syntax error in
config.php in phpVirtualBox's folder. The most common errors are an
unclosed quote or a missing semicolon in a configuration item that has
been entered (e.g. location, username, or password).

Depending on your PHP configuration, navigating directly toconfig.phpin
your web browser may display the PHP error message.

If find that this is not the case, or have no idea what this error
message means, please raise the issue
athttp://sourceforge.net/p/phpvirtualbox/discussion/help/

I can't find any error messages anywhere. Both nginx and php5-fpm report
no errors, and phpvirtualbox doesn't seem to output any logs.
If I browse to config.php, it just shows a blank page. Note that I'm
using the example config.php with no changes.

I am having the same issue except when I navigate to the config.php my entire file shows up?

[Ian Moore]

PHP is not being parsed by your web server and it is instead just serving the raw PHP source. Please see a how-to on setting up PHP to work correctly in your environment. When navigating to config.php, it should be a blank page.

Awesome I think what I missed was this line

sudo apt-get install php5 php5-mysql libapache2-mod-php5

the last lib-mod was not included when I first installed.

Thanks for the quick response.

Just to note, I'm having a similar issue.

On Debian 8.1, with Nginx and PHP-FPM, I'm getting no errors logged, so I checked (via this StackOverflow post) that I had all my error log options turned on, and I'm still getting nothing.

I then realised that actually, adding a phpinfo.php file with the single line "<?php phpinfo();" and calling that wasn't returning anything.... so I re-checked my NGinx config - and it wasn't loading PHP.

Now, your NGINX is likely to be configured differently to mine, but for the benefit of someone following after me - check your PHP is working before you start to blame phpvirtualbox :)

For me was the solution to enable so php_soap.dll inside php.ini.

Edit
nano /etc/php/7.0/apache2/php.ini

Change
;extension=php_soap.dll
To
extension=php_soap.dll

Hellow from Spain. Any ideas for this error thanks.

Hey gusdudu, thanks for getting in touch - I'd never have come looking in this thread otherwise!

As I mentioned above, it sounds like your web server might not be serving PHP properly. I've not used phpvirtualbox (or, for that matter, written any PHP) for around 2 years now, so I don't know why it's serving up the response it is... but you should probably create a file in the path of your phpvirtualbox directory which has the extension .php and which has the text in it:

<?php phpinfo();

Browse to that file using your web browser, and confirm it's actually returning something with tables and boxes in it, rather than just that one line!

If you are getting some kind of properly formatted HTML page back, then you might actually have an issue in your config.php - in which case, run the in-built PHP linting tool (which is to say, it checks for basic syntax errors, and tells you about them) by running:

php -l config.php

This should be run against the config.php file on the machine which will be hosting phpvirtualbox.

If that comes back clean, then.... well, I have no idea, but probably worth posting back, and seeing what happens! Good luck!

Hello all. Please advise for the same php error. I have check all the possible fixes on this forum but seems that nothing is helping. I am running Ubuntu 14.04.05, Virtualbox 5.2.8, phpvirtualbox 5.0.5.

The services are started as vbox user and running ok, there are no errors in config.php, browsing config.php gives blank page.

Any advice would be appreciated. Thank you.

[Thomas]

Hi,

Did you check your web server log file? Is there any PHP error?

Can you attach you config.php here, after having blanked vbox's password in the file?

[Floin Cucu]

Hi.

Thank you for opening my eyes. I have checked the Apache's error log that led me to check PHP version and I've found out that I had installed 7.2 over 7.0 but for some reasons the system was bouncing between the two versions. Just downgraded to 7.0 with packages with unneeded packages autoremove and the problem is now solved. Thank you very much again.

Hi, same error here. After upgrading to Ubuntu 16.04.5 and Virtualbox (5.2?) and PHP7 (reason was it could/should resolve incorrect/out of of sync mouse pointer in console). PhpVirtualbox worked fine before. Spent many days/hours reading many install tutorials and error fixes but finally decided to try my luck here. I'm a linux novice and out of ideas where to look or how to fix it.

vboxwebsrv is running under the user/password as specified in config.php (although before it was started automatically and now I have to start it manually)

I inspected all log files shown by webmin and do not see any error messages related to vboxwebsrv or phpvirtualbox.

Below my config.php. Happy with any clues........
