the key is the length of characters after the starting point...you're
telling it to grab the next 43 characters that follow position 36. have a
look:
<?
$string = "United Parcel Service (1 x 0.55lbs) (Ground):";
$start = strrpos($string, '(');
$end = strrpos($string, ')');
$result = substr($string, $start, $end);
$length = ($end + 1) - $start; // 1 is offset
$expectedResult = substr($string, $start, $length);
echo '<pre>' .
print_r(
array(
'search' => $string ,
'start' => $start ,
'end' => $end ,
'length' => $length ,
'using just end' => $result ,
'using LENGTH' => $expectedResult
),
true
) .
'</pre>';
?>
hth,
me
