Undefined index: REQUEST_METHOD

[Bandit]

Hi there,
I have installed a search engine on one of my websites - it had a few
bugs in it, I got all but one out of the script.

The results page works, but it displays this error on the top of the page:

Notice: Undefined index: REQUEST_METHOD in \www\search\lib s\utils.php on
line 409

I have enclosed the code it refers to below. I am an amateur when it comes
to PHP, and would appreciate any help. Thanks

Line 409 is this first line.

$retVal = $GLOBALS[$envVar];
if (strlen($retVal ) < 1) {
$retVal = getenv($envVar) ;
if (strlen($retVal ) < 1) {
$retVal = $HTTP_ENV_VARS[$envVar];
if (strlen($retVal ) < 1) {
$retVal = $HTTP_SERVER_VA RS[$envVar];
}
}

Use @ to suppress the notice.

$retVal = @$GLOBALS[$envVar];

Or lower your error_reporting level.

Noooooooooooooo . The correct answer is to write better code.

$retVal = $GLOBALS[$envVar];
if (strlen($retVal ) < 1) {
$retVal = getenv($envVar) ;
if (strlen($retVal ) < 1) {
$retVal = $HTTP_ENV_VARS[$envVar];
if (strlen($retVal ) < 1) {
$retVal = $HTTP_SERVER_VA RS[$envVar];
}
}

There are no checks if the index does exist in the array... The
nonexisting key is accessed directly...

if(array_key_ex ists($envVar,$G LOBALS))
{
$retVal=$GLOBAL S[$envVar];
}
elseif(array_ke y_exists($envVa r,$_ENV))
{
...
}
else
{
...
}

As i've found array_key_exist s the most elegant way, isset is faster.

But array_key_exist s has added value: it will barf when the haystack isn't
an array. IMHO that's more important than a few us.

Doing more when less will suffice is vain.
