Regular expression. What is wrong?

[Kostyantyn Shakhov <shakhov@xxxxxxxxxxxxxxxx>]

I have to check the phone number. I use some regular expression for
this. The phone number can contain only numbers and characters like
+,-,),( and space. The problem is when I use a Perl-style all works as
intended but when I use a Posix-style I've got the Warning: ereg():
REG_ERANGE and the result is opposite to intended one. What is wrong
in the following?

 <?php
   $test_phone = "8 (044) 419-0567";

   if(preg_match("/^[+]?[\d\-\040\)\(]+$/", $test_phone))
   {
     echo "valid phone<br />";
   }
   else
   {
     echo "not valid phone<br />";
   }

   if(ereg("^[+]?[0-9\-[:space:]\)\(]+$", $test_phone))
   {
     echo "valid phone<br />";
   }
   else
   {
     echo "not valid phone<br />";
   }
 ?>
