PHP/MySQL arrays/numrows crosstabulation

Question

Im trying to get crosstabulation count with next code (this is relevant piece) wich doesn't work

<?php
foreach($row as &$val_row)
{
    foreach($col as &$val_col)
    {
        $count=mysql_num_rows(mysql_query("SELECT whatever FROM data WHERE 
$field_row='$val_row' AND $field_col='$val_col'"));

        echo $count;
    }
}
?>

Im just getting a hang of using arrays, Im wondering why this doesn't work. I get only $count once right, other results are 0...

In this case, i have crosstabulation of 2 types of answers. Gender (Male, Female), Question (yes,no) My idea was to run trough both arrays with foreach and to build a table, for every field to do a query of current value of array for row and column.. It simply doesn't work.. I think that I'm doing something wrong with recursion or variable lifespan.. I'm realy confused..

Answer 1

The problem was in mysql table data. I had imported data from some lousy .csv As soon as I got correct data in table, everything started working the way it should be... Please delete this question as it doesn't have any logical purpose...
