2 multidimensional array questions

[tarscher]

Hi all,

2 array questions;
I have a multidimensional matrix.
C1 C2 C3 C4
R1[] [] [] []
R2[] [] [] []
R3[] [] [] []
R4[] [] [] []
R5[] [] [] []
R6[] [] [] []
R7[] [] [] []
R8[] [] [] []

1. Is it possible to search in a specific column?
eg: only search for a value in in C2 and get the rownumber as result?

2. Copy one or more rows and put them in between other rows?
eg: move row 5 and 6 between row 1 and row 2.
C1 C2 C3 C4
R1[] [] [] []
R5[] [] [] []
R6[] [] [] []
R2[] [] [] []
R3[] [] [] []
R4[] [] [] []
R7[] [] [] []
R8[] [] [] []

Thanks in advance
Stijn

try :

$fixed_col = 5;

for ($i=1;$i<=row_numbers;$i++) {
if ( $table[$fixed_col][$i] == $search_value ) {
echo "found !";
exit;
}
}
