Comparing values in an array?

[spinfree]

Hi-

I'm trying to figure out how to compare all the values in a given array, and, if they are all the same (equal to NULL, actually), I'd like to unset the array.

Any ideas? Thanks.

Hope this helps.

if (count($blah) < 1) unset($blah);

The count method doesn't work because the array actually contains 9 rows, they are just NULL values.

Try this.

for ($i = 0; $i < count($arr); $i++) {
if ($arr == NULL) {
continue;
} else {
$all_null = false;
break;
}

}
