[RESOLVED] split string

[zzz]

I need to be able to split a string that contains email's "From" information.

I need to be able to extract $NAME and $EMAIL or whatever is available.

The string can be in the following format:

"Santa Clause" <[e-mail]>
Santa Clause <[e-mail]>
<[e-mail]>

I guess it is easier with email,because it is always between < >. So, I'll need some sort of regex formular, right?

Not sure how to go about the name since it could be present with quotes marks, without and sometimes not present at all...

$parts = preg_split('/[\'"<>]( *[\'"<>])*/', $text, -1, PREG_SPLIT_NO_EMPTY);

Then just add a bit of logic where if $parts only has one element, then the name is empty, whereas if it has two elements, then $parts[0] will be the name and $parts[1] will be the email.

That's brilliant. I've added the following:

if (count($parts) == 2) {
	$name = $parts[0];
	$email = $parts[1];
} else {
	$name = '';
	$email = $parts[0];
}

I also came across a few more exceptions. For example, although this line is malformed, the script worked properly:

"Your new Swiss watch here. Lanny Hebert" <steed50

(all those spam messages by the way... 😉

So I'll need to do add more logic on my side to do something else when the email is malformed.

Also there was this sort of input:

[e-mail],

it is recognized as a valid email address, of course, but I need to make sure it does not contain any non-email characters on either side.

Format-wise, I believe that is perfectly valid, if not typical, except for the trailing comma. You could run the emails through [man]filter_var/man, using the FILTER_VALIDATE_EMAIL filter.

Wow, filter_var!? I haven't even heard of this one... Isn't PHP getting even better every day? I love that!

I need to figure out a way to accomplish the same but without the use of PREG_SPLIT_NO_EMPTY flag. If I take it ou, doI need to keep -1 (no limit flag)?

Had some issues with the code and as soon as I took out PREG_SPLIT_NO_EMPTY things started to work. Maybe I am experiencing the bug with that flag as documented in the manual?..

Also, after I took out -1, PREG_SPLIT_NO_EMPTY

$parts = preg_split('/[\'"<>]( *[\'"<>])*/', $text);

in the string like this
Santa Clause <[e-mail]> the count

count($parts )

gives me 1 and not 2... When I output it

echo $parts[0]; // writes Santa Clause

...which is correct but what happen to the email?

Something broke.

Never mind... my bad. The must've been some error on my page because this works great now after I took apart and rebuilt my code.

$parts = preg_split('/[\'"<>]( *[\'"<>])*/', $text, -1, PREG_SPLIT_NO_EMPTY);
