PHP check a email.txt file or MySQL if exists before sending a message

maxtran2005

Hi guys,

I've downloaded couple email list scripts at hotscripts but none of them do what I wanted. Can you help me?

Basically, I have an emaillist.txt (code from this site http://www.phptutorial.info/scripts/mailinglist/) which allow user to subscribe and unsubscribe.

If user selects subscribe, enter an email and that email is already in the emaillist.txt, a message is sent to that email saying thank you you've already subscribed.

If user selects subscribe, and email is not in the emailist.txt, a message is sent saying something like thank you for your interest, your email will be added to our emaillist as soon as possible. (*I will add the email into the emaillist.txt manually)

If user selects the unsubscribe, the message will say... sorry you have to leave etc.

The reason I do this is because I don't want to send out newsletter to those who aren't interested, or that they're not in group or friends.

Any suggestion would be greatly appreciated.

[PHP]
$str = strtoupper(file_get_contents("emaillist.txt"));
if (strpos($str, strtoupper($InputedEmail)))
{//Already in file
}
else
{//New to file
}
[/PHP]
$InputedEmail will have to be declared yourself
strtoupper() lets makes all the characters uppercase to prevent captialization differences.

I just looked at that URL in your post and depending on how much of that you used, you may be able to take out the strtoupper() s and might need one strtolower(). It's up to you, but the code above will work regardless, though it might have redundancies.

Hey, I tested the script, however it doesn't work correctly.

It went to the else statement. Any idea why?

the emaillist.txt file contains

myemail1@yahoo.com,
myemail2@yahoo.com,
myemail3@abc.com

I'm not sure if it matter with breakline, or a comma added after each one

Thanks
