I have this

PHP Code:
<?php
$rows = 7;
$columns = 7;
$numbers = range(1,($rows*$columns));
shuffle($numbers);

for($row = 0; $row<$rows; $row++){
    $this_row = array();
    for($column =0; $column<($columns-1); $column++){
        $this_row[] = array_shift($numbers);
    }
    sort($this_row);
    $this_row[] = array_shift($numbers);
    echo implode($this_row, ' ');
    echo '<br />';
}
?>
it basically produces randomly, 7 lines of numbers, each unique between 7 lines in order, then the last number is not in order although it is counted in the 49

I need to take those lines and compare each individual line in another file to see if any match, but only the first 6 numbers

if they do match I would like a warning to refresh the page in order to re-randomize the numbers

I have been told it can be done by creating an array of numbers from my file. Once I have that, I can compare other sequences to see if they match using in_array()

although I have no clue how to do any of that lol.. thanks
