    Multidimensional Array ?

    Please correct the multidimensiona l array "a" below -->


    Code:
    <html>
<body>

<?php

$input = explode(" ", $_POST['input']);

$row = $input[0];
$col = $input[1];

$k=2;
$a = array();

for($i=0; $i<$row; $i++) {
for($j=0; $i<$col; $i++) {
	$a[$i][$j] = $input[$k];
	$k++;
}
}

}
      What's wrong with it?

          Will the multidimensiona l array "a" be globally available ?

          global $a ;

                  What kind of data does $_Post['Input'] contain?

                  P.S. Your second for loop adds to the index of the first one.
