Re: [PHP] eregi(mail)
Hello friends,
I use the following code, but it does not work. Is there something wrong?
If
(ereg('^[-!#$%\'*+\\./0-9=?A-Z^_`a-z{|}~]+'.'@'.'[-!#$%\'*+\\/0-9=?A-Z^_`a
-z{|}~]+\.'.'[-!#$%\'*+\\./0-9=?A-Z^_`a-z{|}~]+$',
$email_address))
){
Print (Sorry, the email address seems to be invalid.);
exit;
}
Please help.
Denis

Either Google is wrong (probably) or they are now allowing things like
spaces into an email address. There are actually several things that are
not allowed in a standard email address. Here is the code that I use.
ereg('^[-!#$%\'*+\\./0-9=?A-Z^_`a-z{|}~]+'.'@'.'[-!#$%\'*+\\/0-9=?A-Z^_`a-
z{|}~]+\.'.'[-!#$%\'*+\\./0-9=?A-Z^_`a-z{|}~]+$',
$subarray))
I am honestly not sure where I got this code, but it has always worked for
me and I have not found any YET that are good address that this kills. I
have also not found any bad ones YET that this lets through (unless the
domain or user doesn't exist, of course).

You also have to think about what kind of email validation you need. Do
you
really need to control the format of the emails being stored in your
database? Or do you need to control the validity of the emails being
stored
in your database? There is a big difference. A valid email address
isn't
necessarily one that is formated in the way you expect. It is one that

Well.. anyway sorry for going off on a tangent there. In your search for

it
was useful in some tiny miniscule sort of way. :)

One problem (syntax issues aside) is that it doesn't seem to be checking
for anything remotely similar to a valid email address.
Here's what we use. Not 100% perfect but closer than most, I think:
function validate_email ($addr)
{
return
preg_match('/^[^\'\s,;]+([a-z0-9]+[a-z0-9\-]*\.)+[a-z0-9]+[a-z0-9\-]*[a-z0-9]+$/i',
trim($addr)));

Re: [PHP] eregi(mail)
As we all know ARPA is thet university network, funded by the government to
build an information infrastructure that eventually became the internet we
have today. But the standards for text messaging within the ARPA net have
been added to over the years in order to accomodate ever expanding
requirments.
For example I have read that a valid email needn't necessarily require
anything before the @ symbol. The ARPA RFC specifically states that it
does. But [EMAIL PROTECTED] can be just as valid as @foo.bar.com if the the
domain resolves and the server is setup to parse from a catch all account
named ''. Is this not true?
If this is true then eregi(/^[a-z0-9]+/, $email ) wouldn't necessarily be
valid. We could then say that eregi(/^[a-z0-9]*/, $email) is pointless
becuase if nothing has to be there then there isn't any reason to look for
it. And thus we return to the original assertion that ereg('@', $email) is
the only way to know that the string is a properly formated email address.
So why even validate that format beyond the most basic rules (@, length, and
invalid characters)? The result of which is useless, unless the address is
sendable, in which case the string format is irrelevant.

Yes, and those changes are codified into new RFCs which eventually become
standards. By all means have a look at RFC 2822 which, if passed into use,
will obsolete 822.
For example I have read that a valid email needn't necessarily require
anything before the @ symbol. The ARPA RFC specifically states that it
does. But [EMAIL PROTECTED] can be just as valid as @foo.bar.com if the the
domain resolves and the server is setup to parse from a catch all account

Sure, and if a web server is set up to respond to a request like:
SPLEARGH www.boogermax.com/greebles ? 888 *** 3424235667
then web browsers could send it and get something in return, but it
doesn't mean it's a valid HTTP request.
If this is true then eregi(/^[a-z0-9]+/, $email ) wouldn't necessarily be
valid. We could then say that eregi(/^[a-z0-9]*/, $email) is pointless
becuase if nothing has to be there then there isn't any reason to look for
it. And thus we return to the original assertion that ereg('@', $email) is
the only way to know that the string is a properly formated email address.
Properly formatted email address is a term whose meaning derives from a
prescriptive, rather than descriptive, definition. A properly-formatted
email address is one which has been properly formatted in accordance with
the rules governing mail addressing, and nothing any more arbitrary than
that.
So why even validate that format beyond the most basic rules (@, length, and
invalid characters)? The result of which is useless, unless the address is
sendable, in which case the string format is irrelevant.
Why even look for an @ sign then? I can address a message to 'mnc' and it
will arrive just fine - within my zone of control.
The reason that we use standards is to ensure that hardware and software
from various vendors can communicate with each other without unexpected
results. As soon as you start giving that up, you subdivide the internet
into smaller zones of mutual compatibility. About 99.9% of the time, there
is no constructive reason for doing it. Given the flexibility already
allowed in email addressesing, I certainly don't see this as one of the
exceptions.
