[line 59]
RFC 822 Email address list validation Utility

What is it?

This class will take an address string, and parse it into it's consituent parts, be that either addresses, groups, or combinations. Nested groups are not supported. The structure it returns is pretty straight forward, and is similar to that provided by the imap_rfc822_parse_adrlist(). Use print_r() to view the structure.

How do I use it?

$address_string = 'My Group: "Richard" <richard@localhost> (A comment), ted@example.com (Ted Bloggs), Barney;'; $structure = Mail_RFC822::parseAddressList($address_string, 'example.com', true) print_r($structure);

Method Detail

Mail_RFC822 (Constructor) [line 141]

object Mail_RFC822 Mail_RFC822(
[string
$address = null], [string
$default_domain = null], [boolean
$nest_groups = null], [boolean
$validate = null], [
$limit = null])

Sets up the object. The address must either be set here or when calling parseAddressList(). One or the other.

Return: A new Mail_RFC822 object.
Access: public

Parameters:

string	`$address`	—	The address(es) to validate.
string	`$default_domain`	—	Default domain/host etc. If not supplied, will be set to localhost.
boolean	`$nest_groups`	—	Whether to return the structure with groups nested for easier viewing.
boolean	`$validate`	—	Whether to validate atoms. Turn this off if you need to run addresses through before encoding the personal names, for instance.
	`$limit`	—

[ Top ]

approximateCount [line 912]

int approximateCount(
string
$data)

Returns an approximate count of how many addresses are in the

given string. This is APPROXIMATE as it only splits based on a comma which has no preceding backslash. Could be useful as large amounts of addresses will end up producing *large* structures when used with parseAddressList().

Return: Approximate count

Parameters:

string $data — Addresses to count

[ Top ]

isValidInetAddress [line 930]

mixed isValidInetAddress(
string
$data, [boolean
$strict = false])

This is a email validating function separate to the rest of the

class. It simply validates whether an email is of the common internet form: <user>@<domain>. This can be sufficient for most people. Optional stricter mode can be utilised which restricts mailbox characters allowed to alphanumeric, full stop, hyphen and underscore.

Return: False if it fails, an indexed array username/domain if it matches

Parameters:

string	`$data`	—	Address to check
boolean	`$strict`	—	Optional stricter mode

[ Top ]

parseAddressList [line 162]

array parseAddressList(
[string
$address = null], [string
$default_domain = null], [boolean
$nest_groups = null], [boolean
$validate = null], [
$limit = null])

Starts the whole process. The address must either be set here or when creating the object. One or the other.

Return: A structured array of addresses.
Access: public

Parameters:

string	`$address`	—	The address(es) to validate.
string	`$default_domain`	—	Default domain/host etc.
boolean	`$nest_groups`	—	Whether to return the structure with groups nested for easier viewing.
boolean	`$validate`	—	Whether to validate atoms. Turn this off if you need to run addresses through before encoding the personal names, for instance.
	`$limit`	—

validateMailbox [line 619]

boolean validateMailbox(
string
&$mailbox)

Function to validate a mailbox, which is: mailbox = addr-spec ; simple address / phrase route-addr ; name and route-addr

Return: Success or failure.
Access: public

Parameters:

string &$mailbox — The string to check.
