Wouldn't it be far easier to do this at the database level in the query?

Array example:

$total_points_awarded = array(  1 => 17, 3 => 14, 4 => 0, 5 => 1, 6 => 0 );

In this example I would like to remove element # 4 and # 6.

The “key” ( 1,3,4,5,6 ) represents the 
member’s account #.  It is an auto_increment value in a mySQL table

The “value” ( 17,14,0,1,0 ) represents their score.

The application for this is a list of the top 
users.  If someone has 0 points I don’t want to include them.


Any thoughts?  Any help is appreciated.


Look at array_filter()  ... http://php.net/array_filter

 17, 3 => 14, 4 => 0, 5 => 1, 6 => 0 );
print_r(array_filter($total_points_awarded));
