Note Submitter: lihatskiym at gmail dot com ---- Check that value is whole numeric or is whole integer. <?php function whole_numeric($val) { if (is_numeric($val) && floor($val) == $val) { if ((string)$val === (string)0) return true; elseif(ltrim((string)$val, '0') === (string)$val) return true; } return false; } function whole_int($val) { $val = strval($val); $val = str_replace('-', '', $val); if (ctype_digit($val)) { if ($val === (string)0) return true; elseif(ltrim($val, '0') === $val) return true; } return false; } ?> Result will be like this: <?php whole_numeric('-1.0'); // true whole_numeric(0); // true whole_numeric('0'); // true whole_numeric('00'); // false whole_numeric(1); // true whole_numeric('1'); // true whole_numeric('1.0'); // true whole_numeric('1,0'); // false whole_numeric('1.2'); // false whole_numeric('001'); // false whole_numeric(array()); // false whole_int('-1.0'); // false whole_int('-1'); // true whole_int(0); // true whole_int('0'); // true whole_int('00'); // false whole_int(1); // true whole_int('1'); // true whole_int('1.0'); // false whole_int('1.2'); // false whole_int('001'); // false whole_int(array()); // false ?>
