php limit mail ()

this might be easy but I don´t see the way. I have a shopping cart at my side where user can buy things. for this the buyer can imput his email-adress into an input-form. the order is sent with php mail() to the shopowner and the buyer.

I´m looking for a way to limit mail to sent only two email, this for preventing spam. I see the risk that spammers could input a semicolon string like this:

email@examplecom;[email protected];[email protected]

Y can't you validate using .

$validemail = filter_input(INPUT_POST, 'email', FILTER_VALIDATE_EMAIL);
if ($validemail) {
  $headers .= "Reply-to: $validemail\r\n";
}else
{
//redirect.
}

considering your actual question .

<?php
$emails = explode(';',$emailList);
if(count ($emails)<3)
{
if(filter_var_array($emails, FILTER_VALIDATE_EMAIL))
    {
    mail();
    }
  else
    {
    //die    
    }
}
?>

This should work to only pick maximum two emails (the first two):

$emailString = "email@examplecom;[email protected];[email protected]";
$emails = explode(";", $emailString);
$emails = array_slice($emails, 0, 2);
$emailString = implode(";", $emails);
var_dump($emailString);

Outputs:

string(31) "email@examplecom;[email protected]"

You could check the number of email in the string like this:

if(count(explode(';',$emailList))<3)
{
    // send email
}
else
{
    // Oh no, jumbo!
}

This code will explode your email string based on the ; characters into an array while at the same time use a count function on the array and execute one of two scenarios based on the number.
