PHP regex for specific phone number format

Question

im trying to validate phone number in php. The requirements are (0d)dddddddd or 0d dddddddd where d is 0-9. This is what I have right now

if(!preg_match("/^0[0-9]{9}$/", $phone))
{
//wrong format
}

I have tried several similar questions, but still cant understand regex very well. Can anyone help me fix the regex?

"Something like" is not good enough when talking about regular expressions. You have to be as exact as you possibly can be. — Sverri M. Olsen

You could try the below code,

if(!preg_match("~^(?:0\d\s|\(0\d\))\d{8}$~", $phone))
{
//wrong format
}

DEMO

Explanation:

^                        the beginning of the string
(?:                      group, but do not capture:
  0                        '0'
  \d                       digits (0-9)
  \s                       whitespace 
 |                        OR
  \(                       '('
  0                        '0'
  \d                       digits (0-9)
  \)                       ')'
)                        end of grouping
\d{8}                    digits (0-9) (8 times)
$                        before an optional \n, and the end of the
                         string
