. . . IT CAN BE SHOWN IN THE BOX (FLAC-Files), if you want to know the data. . . . So you have data, but who has?. . . . and the BIGGEST PART of all: all this data is PROCESSED by the BIG DATA (The algorithm, this is: the PROGRAM, in this case, since you do not want to use PURE DIGITAL, unless you don't know why), it is already PROCESSED by the PROGRAM. This is my opinion and my experience, if someone want to learn more about this subject, he will have to look at the topics I have already mentioned. IMHO, there are things to learn from this. So, if you do not know, do not try to change your system. These are the rules that I follow.
Q:
PHP Regular Expression
I have an online calculator. Everything works fine except for the checker part. I've tried this checker but it doesn't work.
if (preg_match("[0-9]+", $_POST['amount'])) {
    $amount = $_POST['amount'];
    if ($amount!= $_POST['amount']) {
        echo "There is something wrong.";
    }
}
The amount can only be numbers.
A:
You can try this one:
if (preg_match("/^[0-9]+$/", $_POST['amount'])) {
The regular expression above will match any string that contains only numbers. So, to match an amount that is specified only by numbers, you need to specify this regular expression.
