Matriz

Boas ppl. Tou a tantar criar uma matriz em php, mas não consigo... Tenho o código seguinte:

for($i=1; $i<10; $i++)

for($j=1; $j<10; $j++)

$matriz[$i][$j] = 1;

Isto devia preencher a matriz toda, mas se tentar imprimir algum elemento da matriz fora do ciclo for, não aparace nada, parece k a matriz fica vazia quando sai do ciclo for. Alguém me sabe dizer porquê?

experimenta assim:

<?

for($i=1; $i<10; $i++){

for($j=1; $j<10; $j++){

$matriz[$i][$j] = 1;

echo $matriz[$i][$j];

}}

echo "<br>"

echo $matriz[1][2];

?>

faltavam os parentesis!!!!

abraço Carlos Aparício
