Hi Rob,
I used your formula and got nothing. Below is what I
did. Can you please tell me where I am going wrong?
<?php
$rows = array();
$rows[0] = array(4,11,24, 26,36,38, 45,35,44, 48);
$rows[1] = array(1,0,13, 9,35,33,47, 25,39,55) ;
$row3[2] = array(4,11,24,26,36,38,45,35,44,48);
$row3[3] = array(1,0,13,9,35,33,47,25,39,55);
$row3[4] = array(5,12,14,54,35,36,48,65,55,87);
$row3[5] = array(0,2,55,26,41,36,67,35,36,69);
$row3[6] = array(1,3,13,24,35,42,42,45,39,70);
$row3[7] = array(1,2,3,64,8,37,6,49,35,36,48);
$row3[8] = array(9,11,24,26,16,38,45,35,44,48);
$row3[9] = array(3,0,13,9,35,23,47,25,39,55);
$max_rows = count($rows) ;
foreach ($rows as $curr_row) {
for ($i = 0; $i <= $max_rows; $i++) {
$common = array_intersect( $curr_row, $rows[$i]);
foreach ($common as $key => $value) {
echo "Key: $key; Value: $value\n";
}
echo "<BR>"
}
}
?>
