Printing a multidimensional Array(Matrix)

[serave]

Hi, i need some help printing a mutlidimensiona l array, i can do it
for square Matriz MxM but i need to print an MXN matrix.
here is my code :
function printMatrix($ma trix){
echo "<table width=\"200\" border=\"1\">";
foreach($matrix as $row =$rValue){
echo "<tr>";
foreach($rValue as $col =$cValue){
echo "<td>".$cValue. "</td>";
}
echo "</tr>";
}
echo "</table>";
}

and this is the message i get:
Warning: Invalid argument supplied for foreach()

please help me

Means you are not giving foreach an array argument.

Show the code that creates the $matrix array and the printMatrix() call
and we can go further into your problem.

I used follwing simple code to test the function:

$a=array();
for($i=1;$i<=5; $i++)
{
for($j=1;$j<=5; $j++)
{
$a[$i][$j]=$i+$j;
}
}
printMatrix($a) ;

and it is working fine for me.

So it might be a chance that the array is not 2 dimensional in your
case.
