in my case

i have an array like this Array ( [0] => )

the count is 1 . but i want to get the not null count , inthis case it should be 0 , how can i do this , please help............................

Answer 1

simply use array_filter() without callback

print_r(array_filter($entry));

Answer 2

$count = count(array_filter($array));

array_filter will remove any entries that evaluate to false, such as null, the number 0 and empty strings. If you want only null to be removed, you need:

$count = count(array_filter($array,create_function('$a','return $a !== null;')));
