Send email with only one language

Oldemar

I have email marketing with all language:

<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;

All have mixed emails with all language:

(textarea emails)
blabla1@hotmail.com
blabla2@hotmail.de
blabla3@yahoo.com
blabla4@hotmail.es
blabla5@gmail.es
...

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

(textarea emails)
blabla1@hotmail.de
blabla2@hotmail.de
blabla3@gmail.de
blabla4@yahoo.de
blabla5@gmail.de
...

Can you tell me? I am completey newbie to this.

If by "language" you mean "top-level domain" then you'd first need to split $emails into lines (preg_split on /\s+/), and then preg_grep on /\.de$/ or whatever TLD you want to keep.

$emails = "test@example.com test@example.de test@example.net test@example.com";
echo "<br>preg_split";
$emails = preg_split("/[\s,]+/", $emails);
print_r($emails);

//preg_split Array ( [0] => test@example.com [1] => test@example.de [2] => test@example.net [3] => test@example.com )

$emails = "test@example.com test@example.de test@example.net test@example.com"; echo "<br>preg_grep"; $emails = preg_grep("/^(\d+)?\.\d+$/", $emails); print_r($emails);
//preg_grep

That wont work. Can you help me?

You could do it with just one preg_match_all(), I suppose:

test ="test@example.com, test@example.de, test@example.fr, test2@example.de";
preg_match_all('/(?:^|,|\s)(\S+\.de)(?:$|,|\s)/i', $test, $matches);
print_r($matches[1]);
/*
Array
  (
    [0] => test@example.de
    [1] => test2@example.de
)
*/

Add some code to make the ".de" part of the regex dynamic for whichever TLD you are looking for, and you're good to go. 🙂

NogDog Great 😀
can you have with more strings (, < > " ,) also? Example:

$test ='<test@example.com>, "test@example.de", test@example.fr <test2@example.de>';
having to do with this '/(?:^|,|\s)(\S+\.de)(?:$|,|\s)/i'

 $emails = preg_grep("/^(\d+)?\.\d+$/", $emails);

I'm not surprised that doesn't work. Where did you get that from?

NogDog

Things get a bit messy when you try to account for all valid email formats, but maybe '/\b\w\S+\.de\b/i' would suffice as the regex?
