I'm getting this message showing up in the apache error_log:

PHP Notice: Undefined offset: 21 in
/usr/local/apache2/htdocs/cargo/lpdriver.php on line 104

The offending code line is:

$constraintuno[$k] .= $s." + ";

This is inside a loop where $k is integer and being being incremented on
each iteration. The final value of $k, and hence the size of array
$constraintuno, is of unknown size.

I can get rid of the error message by using array_fill:
$constraintuno = array_fill(0,1000,'');

This is pretty ugly, because I cannot predict the final size of the array.

Is there a good solution?
