For a decent and standardized php function I want to format a user inputted string to a std. international phone number format. The string will be stripped from other characters as digits and +-signs. All spaces will be deleted. After that I want to format the different strings to a standardized form:

+310612345678  -> +31 (0)61 234 5678
00310612345678  -> +31 (0)61 234 5678

+31612345678   -> +31 (0)61 234 5678 
//add a leading zero between brackets (0))
0031612345678  -> +31 (0)61 234 5678

06 12345678   -> +31 (0)61 234 5678 
//When no country code is given (no 00xx or +xx) than add the dutch one.

This is the function which i have allready:

function formatPhoneNumber($num){
 //delete everything except digits and +
  $number = preg_replace('/[^\d|\+]/', '', $number);

 if(substr($number,0,1) == '+' || substr($number, 0,2) == 00){
  //
 }else{
  $number = "+31".$number;
 }

 /////////
 // formatting as mentioned above
 /////////


 return $num
}

  • somewhat comically, the skype firefox addon converts all of those phone numbers to a kind of widget.
  • What is your question? Are you looking for a standard for representing phone numbers (answer here: itu.int/rec/T-REC-E.123-200102-I/e)? Are you struggling with regular expressions for converting a string to another? Are you looking for an algorithm?
  • I am indeed looking for an algorithm to convert those different numbers into one format.
  • how about "vanity" numbers (0800-VANITY)? i got one for my name (123-MYNAME), and i'm always wondering why noone seems to think about this when i get another "wrong input format" error when i try entering this into web applications.
