PHP Send email with only one language

I have email marketing with all language:

Code: 
<form action="email.php" method="post">
<textarea name="emails" value="emails"></textarea>
<input type="submit" value="Subscribe">
</form>
<?php $emails = $_POST["emails"];
//$email = explode/ltrim/array/string/etc ???
echo $emails;



Code: 
All have mixed emails with all language:
(textarea emails)
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
...

But how can I have with one language? example I would have only .de

Code: 
(textarea emails)
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
...
Can you tell me? I am completey newbie to this.

If I understand you correctly you can use explode and array_filter to achieve this.

Use explode to break up the input based on the new line character and then filter out any that don't have a .de extension:

[CODE lang="php" title="Emails"]<?php

$emails = "[email protected]\[email protected]\[email protected]";
$emailsArr = explode("\n", $emails);

$filteredEmails = array_filter($emailsArr, function ($email) {
return preg_match("/\.de$/", $email);
});[/CODE]

You might want to be careful with this, in trusting user input you could end up spamming and having your server ip blacklisted.

The code is only designed to filter out emails with a suffix of ".de". If you output (print_r or something) $filteredEmails you should see "[email protected]" in the array not anything else.

The current code has no output which is why it's blank. I helped with the filtering, so now you have the ability to get the emails that you want to send a message to.

$emails btw should come from $_POST['emails'] (though as I said, remember to validate / sanitize the user input)

PHP: 
<?php
/* for testing purposes
$_POST['emails'] = "[email protected]\[email protected]\[email protected]";
*/
$separator = "\n"; // new line, but could be comma, etc
$extension = ".de"; // the allowed extension

/*
You could also use multiple allowed extensions... use in_array() and a loop or something to check each extension
$allowed = array(".de", ".com.de");
*/

if(isset($_POST['emails']) && strlen(trim($_POST['emails'])) > 0){
    $emails = explode($separator, $_POST['emails']);
    $num_emails = count($emails);
    if($num_emails > 0){
        for($loop = 0; $loop < $num_emails; $loop++){
            $ext_position = strpos($emails[$loop], $extension);
            if($ext_position === false || $ext_position !== strlen($emails[$loop]) - strlen($extension)){
                echo $emails[$loop] . " does not contain or end with $extension<br>";
                continue; // this email does not contain extension, or the extension is not at end of email
            }
            echo $emails[$loop] . " ends with $extension<br>";
        }
    } else {
        // no email list provided
    }
} else {
     // no email list provided
}
?>
