mailparse_rfc822_parse_addresses — Parse RFC 822 compliant addresses
Parses a » RFC 822 compliant recipient list, such as that found in the To: header.
A string containing addresses, like in: Wez Furlong <wez@example.com>, doe@example.com
Hinweis:
This string must not include the header name.
Returns an array of associative arrays with the following keys for each recipient:
| display | The recipient name, for display purpose. If this part is not set for a recipient, this key will hold the same value as address. |
| address | The email address |
| is_group | TRUE if the recipient is a newsgroup, FALSE otherwise. |
Beispiel #1 mailparse_rfc822_parse_addresses() example
<?php
$to = 'Wez Furlong <wez@example.com>, doe@example.com';
var_dump(mailparse_rfc822_parse_addresses($to));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
array(2) {
[0]=>
array(3) {
["display"]=>
string(11) "Wez Furlong"
["address"]=>
string(15) "wez@example.com"
["is_group"]=>
bool(false)
}
[1]=>
array(3) {
["display"]=>
string(15) "doe@example.com"
["address"]=>
string(15) "doe@example.com"
["is_group"]=>
bool(false)
}
}
To just extract the email address out of an RFC822 line, it's faster and more reliable to just use a simple regex such as:
<?php
$rfc = '"Bob Smith" <bob@smith.com>';
preg_match('/[\\w\\.\\-+=*_]*@[\\w\\.\\-+=*_]*/', $rfc , $regs);
$parsed = $regs[0];
?>
The above code will pull out: bob@smith.com
No matter the variation of the RFC822 line, as long as there's a valid email address in it somewhere, the above regex will find it.
An alternative to the mailparse_rfc822_parse_addresses() function is Mail_RFC822::parseAddressList() from Pear:
http://pear.php.net/manual/en/package.mail.mail.php
It parses the string and returns a structured tree of data. Returns a pear_error object if the string is not valid.
Example:
require_once "PEAR.php";
require_once "Mail/RFC822.php";
$addr= "Hi <hi@world.org>";
$res= Mail_RFC822::parseAddressList($addr);
if (PEAR::isError($res)) die("NOT VALID: " . $res->getMessage() . "\n");
echo "OK. Data:\n";
print_r($res);
If for some reason you cannot compile mailparse into your install of PHP, you will also find an extremely similar function in the Mail_MIME PEAR class, specifically in mimeDecode.php.
