In addition to array_filter, you can be more explicit with

$min = min(array_diff($array1, array(0));    // result = 1

This can let you disregard more values very easily, e.g.

$min = min(array_diff($array1, array(0, 1)); // result = 3

Try array_filter:

If no callback is supplied, all entries of input equal to FALSE will be removed.

so it will remove 0 for you.

echo min(array_filter($array1)) . "\n";
