Regexp::Common::URI::tel - phpMan

NAME
    Regexp::Common::URI::tel -- Returns a pattern for telephone URIs.

SYNOPSIS
        use Regexp::Common qw /URI/;

        while (<>) {
            /$RE{URI}{tel}/       and  print "Contains a telephone URI.\n";
        }

DESCRIPTION
  $RE{URI}{tel}
    Returns a pattern that matches *tel* URIs, as defined by RFC 2806. Under
    "{-keep}", the following are returned:

    $1  The complete URI.

    $2  The scheme.

    $3  The phone number, including any possible add-ons like ISDN
        subaddress, a post dial part, area specifier, service provider, etc.

  $RE{URI}{tel}{nofuture}
    As above (including what's returned by "{-keep}"), with the exception
    that *future extensions* are not allowed. Without allowing those *future
    extensions*, it becomes much easier to check a URI if the correct syntax
    for post dial, service provider, phone context, etc has been used -
    otherwise the regex could always classify them as a *future extension*.
