[Erik W Gilling]

Add a check and use doubleval if PHP is too old.

Mine also complained about mysql_real_escape_string being
missing.

I just added this to a separate file & included it in the
luaparser.php:

function floatval($strValue) {
$floatValue =
ereg_replace("(^[0-9]*)(\\.|,)([0-9]*)(.*)", "\\1.\\3",
$strValue);
if (!is_numeric($floatValue)) $floatValue =
ereg_replace("(^[0-9]*)(.*)", "\\1", $strValue);
if (!is_numeric($floatValue)) $floatValue = 0;
return $floatValue;
}

function mysql_real_escape_string ($string) {
return mysql_escape_string($string);
}
