[RESOLVED] the argument should be an array error

[jrough]

$addr = $_POST['q'];
$addrArray= unserialize($addr);

$addrUnique = array_unique($addrArray);

if(array_count_values($addrUnique)>200 )
{
    echo "The maximum addresses are 200 or less  at a time.  You are over the limit.";
	exit;
}

I'm getting the error message "The maximum addreses are 200 etc etc." but I don't have more than 200 addresses so something is wrong. I have the $addrArray which is an array of addresses with a numerical key. I need to count the unique values to make sure it doesn't go over 200. If it does I have to exit. I have also the need to check that I have only unique values. Is the problem I have to loop through each one? If so is it a for each loop?
thanks,

The array_count_values() returns an array.

I am not entirely sure exactly how, when it returns an array its greater than 200.

Try:

if (sizeof($addrUnique) > 200) {
    echo "The maximum addresses are 200 or less  at a time.  You are over the limit.";
    exit;
}

array_count_values() should return the unique elements, as well as the # of elements in there.

You could potentially also do:

if (sizeof(array_count_values($addrUnique)) > 200) {
    echo "The maximum addresses are 200 or less  at a time.  You are over the limit.";
    exit;
}

Best of luck

Thanks that got rid of one error but would you mind telling me what is wrong with array_unique($addrArray)? Google maps can't post if there are duplicate values. I should check for it separate from the count I'd say.
thanks for your post,
$addr = $_POST['q'];
$addrArray= unserialize($addr);
print_r($addrArray);
$addrUnique = array_unique($addrArray);

if(sizeof($addrUnique)>200 )
{
echo "The maximum addresses are 200 or less at a time. You are over the limit.";
exit;
}
