PHP: blank page

[getmizanur]

elloo,

 

i have php script that works fine on a dev server however on staging server it is a blank page. i have set 'error_reporting(E_ALL) ' and ini_set('dsiplay_errors', 1) however only information i get is some notices and no fatal errors.

 

i'm aware that php stops executing if there is a fatal error (and appears as blank screen), is there some sort of directive in 'php.ini' which stop php from executing when there are notices. 

 

thanks in advanced

Notices CAN stop a page from working. If a notice occurs before a header() or session_start() or set_cookie() or other function that wants to send a header to the browser, then that function call will fail. Of course you should get a notice or warning (I don't know which). So, look for a message about headers already sent.

 

If you post your code and error messages, we may be able spot some potential problems, but my crystal ball is a bit foggy today.

Even if you spelled "display_errors" correctly in your code, ini_set() in a file won't affect PHP if there are parse errors. Which are 99% of the time the causes of blank screens.

You have to change error_reporting and display_errors in your php.ini to be able to see typical parse errors.

i realised that you cam check for syntax error by execute php script on the command line. in this case, i forgot to install php5_mysql package, d'oh.
