Grabbing specific info from sting

[Anon]

Im grabbing the information from an email.
Now i need to take the email address from the 'From:' part of the email.

This is what the 'From:' looks like from an incoming email:

"Derek Comartin" <[e-mail]>

Now what want to do is to grab the email address after wards and nothing else...

So i just want this:

[e-mail]

Any ideas of how going about doing this ?

[Anon]

Try this:

$from = '"Derek Comartin" <[e-mail]>';
$email_only = substr($from, (strrpos($from, "<")+1), -1);
echo $email_only;

[Anon]

Works like a glove thanks..

i think ill ahve to look into substr and strrpos a little see exactly how those work.

Thanks again

Running into bit of a problem..
Your exact code works perfect:

$from = '"Derek Comartin" <[e-mail]>';
$email_only = substr($from, (strrpos($from, "<")+1), -1);
echo $email_only;

BUT now here is my problem... where
"Derek Comartin" <[e-mail]>

this is going to be different all the time, so this is the code i used:

$email_only = substr($fromperson, (strrpos($fromperson, "<")+1), -1);
echo $email_only;

now $fromperson will be something like this but always different because of who is sending etc:

"Derek Comartin" <[e-mail]>

This is what will come up with my modified code:

quot;Derek Comartin" <[e-mail]>

Any ideas?

[Anon]

The only thing you changed in your code is the name of the From: variable.

Your new example works fine on my end...

[Anon]

Yes i just changed the From: variable

The variable im using is $fromperson

if i do echo $fromperson;

it will get

"Derek Comartin" <[e-mail]>

Now since $fromperson is already defined i just changed teh From Variable. So my code is now:

$email_only = substr($fromperson, (strrpos($fromperson, "<")+1), -1);
echo $email_only;

and i return:

quot;Derek Comartin" <[e-mail]>

Sheesh...what is going on?

Check it out: http://www.socket7.net/derek.php3

It's working...

[Anon]

Ok maybe i wrote it a bit wrong what the problem is.. here is exactly what im doing..
Now i created a web-based email program, no im at the point where once you selected a new incoming message and you go to readmail.php3

This lets you view the message you selected.
Now teh code to grab the email header information is fine.. in your email header i have a variable to print the From: information which is $fromperson.

If you emailed me the $fromperson would be something like

"Brett" <[e-mail]>

So $fromperson code is already set.
If i did echo $fromperson it would print

"Brett" <[e-mail]>

Now im usinjg your exact code but now instead of using $from im using $fromemail
seems to me like it shouldnt be a problem but.

Here is all the code that might help understand.

Code im using to just take email from From:
$email_only = substr($fromperson, (strrpos($fromperson, "<")+1), -1);

Code to get $fromperson:
f(strcasecmp(substr($buffer,0,5),"From:")==0) {
$fromperson=substr($buffer,6,strlen($buffer)-6);
$fromperson=htmlspecialchars($fromperson);

[Anon]

Sounds like you are doing everything right...I really don't know where the problem is.

Anyone else have some input?

[Anon]

The only thing I can think of is that you may be running an htmlspecialcharacters before you run the code to get the email from the fromline. A message you left earlier leads me to beleive you that this is your problem.
Right before you run the code to parse out the email try echoing the fromline. You should get something like this :
"Derek Comartin"
The <[e-mail]> wont be there because the browser will think it's an unidentified html tag.

[Anon]

I ran into that when I was testing different things. I noticed you (Derek) used htmlspecialchars() and I used htmlentites(). It really shouldn't make too much difference since htmlspecialchars() only escapes '<', '>', '&', '"' of which you only need three....

No, the point is that if he runs something like :

$fromline = htmlspecialchars($fromline);

or

$fromline = htmlentites($fromline);

then runs :

$frommail = substr($fromline, (strrpos($fromline, "<")+1), -1);

It wont work correctly... not at all really. The strrpos() is searching for "<", but if you convert html entities firs then there wont be any "<"s in the fromline. They'll all have been converted to &lt;.

[Anon]

Just like that... my &lt; got converted to a <. Uhm... what I meant to say was that the < will have been converted to &#38;lt;.

[Anon]

I get it... yes. You are correct.

[Anon]

Alright guys just got back to work after the holiday weekend! Im going to give this a few tries hopefully this will work. Thanks for all the help guys. Much appreciated.

[Anon]

Alright this is starting to come together better then what it was.. Now here is the code im using: (sorry i changed it around a bit)

if (substr($linje, 0, 6) == "From: ") { $fra = substr($linje, (strrpos($linje, "<")+1), -1);

Now this will give me:

[e-mail]>

For some reason the -1 isnt doing anything. So everything is working fine except its not going back one space to get rid of the > at the end. Any ideas?

[Anon]

Your new code works perfectly on my end...
