As Arrays are passed by value and not by reference, you can define the
new array outside the for loop.

$myArray = array();
$newArray = array(0, 0, 0);
for ($i=0; $i<10000; $i++) {
$myArray[] = $newArray;
}

or

$myArray = array();
for ($i=0; $i<10000; $i++) {
$myArray[] = array(0, 0, 0);
}

I don't know which is faster.
Anyway this does not explain the undefined offset notice, and it does
not really answer why one should do this at all :-)
