When a valid delimiter is supplied with no limit, then the result is
the same as if the limit was the count of items after the split.
For negative limits (with a valid delimiter), the result is chopped by
the abs($limit).
<?php
$string = 'one.two.three.four';
$results = array();
foreach(array('Valid' => '.', 'Invalid' => '_') as $valid => $delimiter) {
$results[$valid]['No Limit'] = explode($delimiter, $string);
foreach(range(-4, 4) as $limit) {
$results[$valid][$limit] = explode($delimiter, $string, $limit);
}
}
print_r($results);
?>
outputs what I think is correct.
