Re: [PHP] displaying database output in a table
Hello Everyone, Thanks for all your suggestions. Unfortunately, I've replaced require_once with include_once and require with include in all the documents, I'm still not having any luck. Thanks.

We struggled with this as well. require terminates the process without any indication of why it stopped. No error, no exception, not even a whimper. Recording a basic "file not found" message in the error log would be a major improvement.

Also, I've been led to believe that $_SERVER variables are a point of entry for injection attacks, so shouldn't be relied upon, although I'm sure that's not the case for everything in the $_SERVER array. I think this is the reason why a lot of systems and frameworks have a config file which require the paths to be set up completely, without relying on these special global arrays.

"/dbconnect.php"); I ran into a similar issue yesterday. Tracked it down and figured out the "required" file did not exist. It didn't show up in my dev environment b/c I had the file. When we pushed it to QA, the file had not been uploaded. The require_once() stops execution if the file isn't found. Try changing it to include_once() and see if you can _any_ output.

Is that last part correct, or did you miscopy? It appears there's no
opening bracket on this if:
if (!($result = @ mysql_query ($query, $db)))
Which would mean that only the next statement is impacted by the if. And,
the next statement, which calls your displayEvents() function, is only
called if the query is unsuccessful.

How have you turned on the error reporting (I assume you meant that and
not debugging, which is quite different) If you've turned it on from
within PHP, then a fatal error could well result in a blank screen. Try
turning the display_errors on in the .htaccess, or preferably the
php.ini file. If you can't, then just take a look at the raw logs
(usually kept in /var/logs)
Also, I'm not sure you can use $_SERVER['DOCUMENT_ROOT'] in a cli
script, as I believe the $_SERVER is only set when PHP is running in a
web server. Are you sure that this is being correctly populated by your
server and that it is attempting to pull in the file correctly?
If the file is being pulled in correctly, is it connecting to the
database?
I would try to avoid jumping in and out of PHP code whilst inside a
function or loop, as it can lead to hard to read code. As it's very
simple html output you're after, have you considered using heredoc or
nowdoc syntax for it? You won't have to break out of PHP for a few lines
of output, and you can keep code nicely formatted and easy to read.
