Line "$value = trim($value);" does not change $array[$index] since 
"unset" was called. See image #1 and values of $value and $array[$index] 
at bottom of the image. At least it is so on PHP 5.2.1. Array always 
stays as is after the first unset line. I found it because EM shows 
garbage while trying to update tables (see image #2). Should be changed 
to explicit value setting if there was unset I think.
