Hello, I am very new to PHP and I am focusing on
arrays to speed up my learning curse on the programme.
The following is an array I am working with and I am
stuck. Can anyone help please?
<?php
// The following is a table
$row_1 = array(4,11,24,26,36,38,45,35,44,48);
$row_2 = array(1,0,13,9,35,33,47,25,39,55);
$row_3 = array(5,12,14,54,35,36,48,65,55,87);
$row_4 = array(0,2,55,26,41,36,67,35,36,69);
$row_5 = array(1,3,13,24,35,42,42,45,39,70);
$row_6 = array(1,2,3,64,8,37,6,49,35,36,48);
$row_7 = array(9,11,24,26,16,38,45,35,44,48);
$row_8 = array(3,0,13,9,35,23,47,25,39,55);
$row_9 = array(5,12,15,14,35,36,43,65,55,87);
$row_10 = array(0,5,55,26,31,36,67,35,36,69);
$row_11 = array(1,3,17,24,34,42,42,45,33,70);
$row_12 = array(1,1,3,66,8,37,6,49,35,36,48);
$row_13 = array(0,2,55,26,41,36,67,35,36,69);
$row_14 = array(1,3,13,24,35,42,42,45,39,70);
$row_15 = array(1,2,3,64,8,37,6,49,35,36,48);
$row_16 = array(9,11,24,26,16,38,45,35,44,48);
$row_17 = array(3,0,13,9,35,23,47,25,39,55);
$row_18 = array(5,12,15,14,35,36,43,65,55,87);
$row_19 = array(0,2,55,26,41,36,67,35,36,69);
$row_10 = array(1,3,13,24,35,42,42,45,39,70);
$row_21 = array(1,2,3,64,8,37,6,49,35,36,48);
$row_22 = array(9,11,24,26,16,38,45,35,44,48);
$row_23 = array(1,0,13,9,35,33,47,25,39,55);
$row_24 = array(5,12,14,54,35,36,48,65,55,87);
$row_25 = array(0,2,55,26,41,36,67,35,36,69);
$row_26 = array(1,3,13,24,35,42,42,45,39,70);
$row_27 = array(1,2,3,64,8,37,6,49,35,36,48);
$row_28 = array(9,11,24,26,16,38,45,35,44,48);
$row_29 = array(3,0,13,9,35,23,47,25,39,55);
$row_30 = array(5,12,15,14,35,36,43,65,55,87);
$row_31 = array(0,2,55,26,41,36,67,35,36,69)
// Next is to find the common element(number) in each
row
$common = array_intersect($row_1, $row_2);
foreach ($common as $key => $value) {
echo "Key: $key; Value: $value\n";
}
echo "<BR>"
?>
My problem is the above works only on $row_1 and
$row_2, and I am stuck.
My question is two-fold. The first is, how do I write
the LOOP to get $row_1 to go through and intersect
with the rest of the rows in the table, that is, to
intersect with $row_3, $row_4 etc and not just stop at
$row_2?
The second question is; if the LOOP goes through to
the end, how do I get it to start at row $row_2 as the
main interceptor to repeat the process, after that
$row_3 and so on and so forth.
