Question

Right now I am using this on my string substr($row->review[$i] , 0, 120) but I would like to take it a bit further and after I limit it find the last period and take out everything after. Any ideas?

$a = 'string you got with substr. iwehfiuhewiufh ewiufh . iuewfh iuewhf 
     iewh fewhfiu h. iuwerfh iweh f.ei wufh ewifh iuhwef';

$p = strrpos($a, '.');
if ($p !== false) // Sanity check, maybe there isn't a period after all.
  $a = substr($a, 0, $p + 1 /* +1 to include the period itself */);
echo $a;
