Ask how to judge a string is a mailbox format and can exist multiple.

Currently I can judge the mailbox format
function Is_email ($email) {
return strlen ($email) > 6 && preg_match ("/^[\w\-\.") +@[\w\-]+ (\.\w+) +$/", $email);
}


The goal is to be able to judge and send multiple people after a comma is separated.

Greatly appreciated

You can split the array with commas.
Then foreach calls your method to judge.

For example:

$emails = ' abc@test.com,efg@test.com '; Var_dump (Checkemail ($emails)); function Checkemail ($data) {        $ret = true;    $emails = Explode (', ', $data);    foreach ($emails as $email) {        if (!) ( strlen ($email) > 6 && preg_match ("/^[\w\-\.] +@[\w\-]+ (\.\w+) +$/", $email))) {            $ret = false;            break;        }    }    return $ret;}

Var_dump (Checkemail ($emails));

function Checkemail ($data) {

$ret = true;
$emails = Explode (', ', $data);

foreach ($emails as $email) {
if (! ( strlen ($email) > 6 && preg_match ("/^[\w\-\.] +@[\w\-]+ (\.\w+) +$/", $email))) {
$ret = false;
Break
}
}

return $ret;

}

Thank you for the answer, now just see embarrassed.
You mean to judge whether each is a mailbox, not a word to terminate the loop, yes, in the back of the statement to do their own operations?
