A weird problem that probably has a comma in the wrong spot....

In php.ini, set error_reporting = On
Note if you override that somewhere, then change it at the overriding
point. Also, there may be some application specific setting, like in
Drupal, you can configure whether the errors are written to the dblog or
dblog and screen.

By most users I assume you mean the developers, as it's not a very good
idea to display errors to actual users of your app (it gives information
away which could be used to break your system and allow them access to
your server)
There is a section inside the php.ini that you can use. Look for the
display_errors flag and set it to on. Just above or below that line
should be another which determines the exact type of errors to display.
The documentation within the ini file itself should show you some
examples.
Thanks,
Ash

Oops oops oops. I put the wrong setting, change display_errors to On.

if(true) // TRUE for debug only
{
ini_set("display_errors", "on"); //use off if users will see them
error_reporting(E_ALL);
$error_reporting = '<span style="color:red">Error display and logging
on</span>';
}
I echo $error_reporting in the body of of my html page to remind me it is on.
This also creates an error log in the working dir.

This won't work if the error is so severe as to prevent PHP from
correctly running. It's always best to set things in the php.ini file,
which should always be accessible on a local development machine.

True. But then you usually get a server 500 error anyhow.

I've just built an experimental component logAndHandler which will
display php errors in a developer & user-attractive way, but it is in
it's infancy.
For instance, some startup errors don't make it into the logAndHandler
window yet, which can be considered a bit of a problem for an error
handler ;)
I will continue work on it though, i'm using it myself for my
commercial projects.

Hi Everyone!
So I'm sitting here trying to get my RSS feed to work off of my main
database login script so that I can centralize the management of the
whole blasted thing, you know... stuff like only having the password
in one place to log into the DB :)
I can connect just fine if I include all the connection stuff locally
in my file, but when I try and include it so I don't have to reinvent
the wheel it says it can't connect.... Host, Username, & Password have
all been checked and doubled checked. And actually the database
connection script works just fine since I'm using it to pull the
content from my main page and that's working just fine...
Here's the code I'm using locally on the page:
<?PHP
$server = "localhost";
$username = "realusername";
$password = "realpass";
$database = "realdatabase";
$linkID = mysql_connect($server, $username, $password) or die("Could
not connect to host." . mysql_error());
mysql_select_db($database, $linkID) or die("Could not find
database." . mysql_error($linkID));
?>
That code works...
When I change it to:
<?PHP
$linkID = dbconnect($server, $username, $password, $database) or
die("Could not connect to host." . mysql_error());
?>
with that function defined as:
<?PHP
function dbconnect($server, $username, $password, $database) {
mysql_connect($server, $username, $password) or die("Unable to
connect: ".mysql_error());
mysql_select_db($database) or die("Unable to select
database:".mysql_error());
}
?>
that will not work on my rss feed. But it does work on my main page
which uses the dbconnect script. The only error that I'm getting is
the one set in my dbconnect call... "Could not connect to host".
So can anyone see where I'm missing my comma or semicolon? :)

Are the MySQL ports open and available on both servers?

Hey Ash,
Yes they are. It's on the same machine so ports shouldn't be an issue
I would think?

Your dbconnect function is not returning a value, defaulting to a null
return value. That means the or statement runs the die statement -
even though you're connecting.

Hey Peter,
That was the problem... The reason it was working on the main page is
I didn't have a "Or die()" statement on the main page...
Now I'll be setting a return value on there so that it works for all
of them :)
Thanks for pointing out my stupidity :)
