split a word from string and save it in a variable

I've a question. I have a string, like this: hello, I am a string, -how are you?-.

And I want to put any text in - - sign in another variable and remove it from original string (in short: cut it!).

How can I do it? I should do it with preg_match or preg_split?

If you help me, I will grateful to you!

It's really two separate operations, but you can use the same pattern for both

$str = "hello, I am a string, -how are you?-";
$pattern = "/-(.*?)-/";

if ( preg_match( $pattern, $str, $matches ) )
{
  $matched = $matches[1];
  $str = preg_replace( $pattern, '', $str );

  echo $matched, PHP_EOL, $str;
}

Note that this assumes that (and therefore only works when) only one section of text is demarcated by -

I believe this is what you are looking for is along the lines of:

preg_match("/\-[\d,\w,\s]+-/gi",'blah blah -hello world-',$myvar)

Now you can use $myvar. It'll return an array of results, so in this case you could use $myvar[0] and it'll return the first one -hello world-

A simple string split using explode (no regex needed) may help:

$s = 'hello, I am a string, -how are you?-';
$parts = explode('-', $s);
print_r($parts);

// Prints:
// Array
// (
//     [0] => hello, I am a string, 
//     [1] => how are you?
//     [2] => 
// )

You can also use trim functions to remove whitespace.
