warning: Undefined index warning

[Anon]

Hi I want to output some values from MySQL, but some column values are blank, which generates error

while ($row = mysql_fetch_array($result))
{
$t_too= $row["pealkiri"];
$t_pealkiri= $row["kirjeldus"];
}

how can I prevent this kind of error??

Warning: Undefined index: kirjeldus in C:\Inetpub\wwwroot\ooindex.php3 on line 73
Thanx...

try: isset();

if isset($row["pealkiri"])
{
$t_too= $row["pealkiri"];
}
if isset($row["kirjeldus"])
{
$t_kirjeldus = $row["kirjeldus"];
}

I haven't found the real reason yet, why PHP (since 4.0.4, I guess) wants variables to be declared!

The simplest way to supress it, is to put an '@' before any variable or array, that cause errors, like
@$my_var or
@$array['unknownindex']

It seems only to be the CGI version
that does this. The ISAPI version
works fine. The @ does work though.

Found sth. else:

Pre 4.0.4 version had (afa I remember) this setting as default Error output in php.ini:
E_ALL & ~E_NOTICE

My version of 4.0.4 did print ALL errors, including notices, which can safely be turned off again (cmp above).

Well, I'm using v 4.1.2 and my error_reporting (in php.ini) has what appear to be the old default setting -- error_reporting = E_ALL & ~E_NOTICE. Which should mean that it shows all errors except "notices" such as undefined variables and the like. However, I'm still getting these errors about uninitialized variables and undefined indexes.

USing the isset() function (or '@' does keep it quiet), but as a lazy PHP programmer this seems like overkill. Anyone know how exactly to set the error_reporting in php.ini in order to shut the php parser up?

Thanks,
Rob

I would think using the @ would potentially suppress errors that one might want to see. Using the isset() at least specifies the intention and other issues will come through appropriately, no?

in the php.ini file change "error_reporting"

to

error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR;

If you guys still have any trobules then mail me!
