I don't see my error, I think. Problem is that only
var_dump($statementNo) displays text(and $statementNo is !empty).
Neither var_dump($message) nor die($message) nor echo '#' displays
text. Function writeToLog() correctly writes to log file.
I failed to run debugging.
Here is my code:
// import_statement.php:
var_dump($statementNo); // works fine
if (!empty($statementNo)) {
error(ERRMSG_STATEMENT_ALREADY_IMPORTED); // enters error()
}
echo '#'; // here problem
// functions.inc.php:
function error($message) {
global $currentUser;
if (ob_get_length() !== false) {
ob_end_flush();
}
var_dump($message); // here problem
$page = $_SERVER['SERVER_NAME'] . '/' .
trim($_SERVER['REQUEST_URI'], '/ ');
$website = trim(ltrim(ltrim(WEBSITE_PUNYCODE, 'http:'), 'https:'),
'/ ');
$page = mb_strstr($page, $website);
$page = trim(mb_substr($page, mb_strlen($website)), '/ ');
writeToLog(null, null, $currentUser, null, null, null, "Application
error: $message Page: $page"); // works fine
die($message); // here problem
}
Please help. Thanks in advance.

OK, do you have the following in your php.ini file (on your development
system):
display_errors=on
error_reporting=E_ALL // or E_ALL | E_STRICT

I added these two lines to my code (before problem):
ini_set('display_errors',1);
error_reporting( E_ALL);
but it didn't help: no error is displayed, I don't know why.

error_reporting(-1)
is e_all + e_strict.
Having E_STRICT set, it'll punish you for passing an undefined constant
to that function. ;)

Is that code possibly placed in an errorhandler?

Although I couldn't find it documented anywhere, I made the experience,
that any var_dumps() after an ob_end_clean() don't get displayed. Maybe
it's the same with your ob_end_flush()?

OK, do you have more than one output buffer?
In fact, why are you using the ob_xxx functions at all? They just add
extra load to the server and server no useful purpose except in a few
very specific cases.

No, it's not. The file import_statement.php is opened via
header('Location: import_statement.php'). The quoted lines are at top
level, not nested in a function.
