thx, it works fine (with string cast and strict mode):
<?php
function _bccomp($a, $b, $operator = '=', $strict = true)
{
if (($strict) && !preg_match('/^[0-9]+$/i',$a)){ return false;}
return version_compare(bccomp((string)$a, (string)$b), 0, $operator);
}
echo (_bccomp('21474836470001', '21474836470001','='))?
'true':'false', "\n"; // true - is same
echo (_bccomp('21474836470001b', '21474836470001a','>'))?
'true':'false', "\n"; // false -is less
echo (_bccomp('21474836470001a', '21474836470001a','>'))?
'true':'false', "\n"; // false -is greater
echo (_bccomp('21474836471h', '21474836471h','='))?
'true':'false', "\n"; // false - not only in numbers with strict,
because of "h"
echo (_bccomp('21474836471', '21474836472','<'))?
'true':'false', "\n"; // true
echo (_bccomp('214748364710', '21474836472','>'))?
'true':'false', "\n"; // true
?>
