3rd Array based on 2 arrays

[zevious]

I need to take an array (array2), compare that to array1, based on a certain field and then save it to array3.

How can I do that? I could probably do it without comparing a specific field some all of the fields on a row will match on the other array. I am looking for the fastest method of doing this, of course.

TIA!

do u want this?..

$row=mysql_fetch_array(mysql_query("QUERY"))
$fields = mysql_list_fields("$db_name", "$table_name");
$columns = mysql_num_fields($fields);
for ($i = 0; $i < $columns; $i++) {
$db_field=mysql_field_name($fields, $i);

    echo("$db_field = $row[$db_field]"); 

    if(SPECIAL_VALUE == $row[$db_field]){ echo " something to do"}

}

No, I have 2 mysql queries stored in arrays and I need to combine them into a 3rd array minus the dupes. Basically I am outputting array 1 and then I need to out another array without the results of array 1.
