Hello.

1. In the form I have a field 'phone' where I am using mask (xxx)xxx-xxxx. Then I am sending this to php file to $phone. How to get only digits in $phone?
2. How to check in php file if data form field $topic is not empty. And if it is empty how to stop the script .

is this correct?
(xxx)xxx-xxxx

$phone = preg_replace("/\(\d\d\d\)\d\d\d\-\d\d\d\d/i","/\d\d\d\d\d\d\d\d\d\d/i",$phone);

A simple way to strip out all non-digits:

$phone = preg_replace('/[^0-9]/', '', $phone);

Thx.

Could u (or somebody)tell me why in this code

$phonenumber = preg_replace('/[^0-9]/', '', $phone);
if ($phonenumber = "1"){
            echo "is1";
          }

if ($phonenumber = "2"){
            echo "is2";
          }

in result I get

is1is2

when $phonenumber was 2.

...thx....but how to stop script in this case? Is in PHP any function like stop_script() 🙂? This will be my last question this week🙂

[dagon]

you probably want something like this:

	if($phonenumber == "1"){
		echo "is1";
	}elseif($phonenumber == "2"){
		echo "is2";
	}else{
		echo "Not 1 or 2";
	}

as for stop_script() that would be exit()

Thank You !! . This example opens new ways for me🙂

Also take a look at the switch construct if you expect to have many different cases.
