PHP syntax error causes no output

I just started a new project on a new virtual server.
If I write a small script, it executes fine.

If there is an error in the small script, I get no output at all,
but the browser shows "done."

here is the small script:
session_start();
$debug=1;
if ($debug) {
error_reporting(E_ALL);
echo "
SESSION:
";
print_r($_SESSION);
echo "
POST:
";
print_r($_POST);
echo "
";
}
echo " duh";
echo "double duh";
?>

If I remove the semicolon after echo " duh"; to generate a syntax
error, I get no output at all. no error is reported in the browser.

Any ideas ?

Check the error_reporting and display_errors in php.ini

I get this on our live servers all the time but we can't turn the
reporting on, so I usually download to an internal dev machine
and test on there with all errors/display on.

I forgot to mention that this is a new php5 installation on a
remote host. But the same thing happens when I request it be
executed as php4 (by changing the extension to php4).

Why not turn the reporting on and display off? That way you'll at
least have a logfile to examine when bad things happen.

You need to enable error reporting and/or display errors in php.ini.
If it's turned off there and there's a syntax error your call to
error_reporting() will never happen since the code cannot be compiled,
much less executed.

php.ini has a blank for display_errors and 2047 for error_reporting.

using ini_set, what are valid values for display_errors ?

You can't use ini_set to display syntax errors. Since there is a syntax
error, none of the code gets executed - including syntax errors.

Well, heck. I can reach the ceiling by pulling myself up by my
bootstraps.

Because the web host runs php as a fastcgi, they had to create a
php.ini in my cgi-bin directory that I could edit.

Thanks all, now all is well.

A poor workaround. Get a development system going. You should never
have display_errors enabled on a production system.
