printing 2 dimentional array

[stijn0713]

I try to write a small function to print a two dimentional array but it doesn't print the value of the array, even if i use the double quotes for variable substituation?

 

<?php 

function printvierkantematrix($matrix, $m, $n){

$tabel = "<table>";

for ($y = 0; $y <= $m-1; $y++){

	$tabel .= "<tr>";

	for ($i = 0; $i <= $n-1; $i++){	

		$tabel .= "<td>$matrix[$y][$i]</td>";	
}

	$tabel .= "</tr>";

	}
$tabel .= "</table>";

echo $tabel;

}
?>

.

 

What's wrong? Is this not a good way of printing arrays?

Php needs to be shown where array variables start and end at inside of a double-quoted string, by surrounding the array variable in {} -

 

$tabel .= "<td>{$matrix[$y][$i]}</td>";

Ok, thanks. Sometimes those are weird decision but ok. I also got it by doing "<td>" . $matrix[$][$] . "</td>"; I guess its the same?

 

thanks !
