The official Wordpress documentation can be found here.

separate resulting values from a foreach with commas – WordPress

I am saving values with add_user_meta within the same meta key.

What I need is to separate them with commas when getting them with foreach so I can send them by wp_mail.

I need something like this:


[email protected], [email protected], [email protected]

but when obtaining them directly, it returns them all together and glued.

some help?


$email = get_user_meta ($vendor_id, 'list_email', false);

foreach ($email as $emails) {
    echo $emails;
}

Result:


[email protected]@[email protected]

I tried some options, but the comma in front must be from the second email to be readable in wp_mail and I don’t understand how to do it

    You just need to append the "," in your loop and then remove the last "," using PHP rtrim() function.
    This code will do what you want:

    $email = ['[email protected]', '[email protected]', '[email protected]', '[email protected]'];
$output = '';
foreach ( $email as $emails ) {
  $output .= $emails . ', ';
}
$output = rtrim( $output, ', ' );
echo $output;

    The output:

    [email protected], [email protected], [email protected], [email protected]

    Edit: Thanks Vee for mentioning, there is way simpler solution for this that is Using implode() function, like this:

    $email = ['[email protected]', '[email protected]', '[email protected]', '[email protected]'];
$output = implode(', ', $email);
echo $output;

    Result:

    [email protected], [email protected], [email protected], [email protected]

    Tip: Always try to use proper names for your variables, here you should use $emails for the array of emails and $email for the single email item.

    If emails are array like this.

    $emails = ['[email protected]', '[email protected]', '[email protected]'];

    Use array_key_last().

    if (! function_exists("array_key_last")) {
    /**
     * Get last array key for PHP version older than 7.3.
     *
     * @link https://www.php.net/manual/en/function.array-key-last.php#123016
     * @param array $array
     * @return int|string|null
     */
    function array_key_last($array) {
        if (!is_array($array) || empty($array)) {
            return NULL;
        }
       
        return array_keys($array)[count($array)-1];
    }
}
foreach ($emails as $index => $email) {
    echo $email;
    if (array_key_last($emails) !== $index) {
        echo ', ';
    }
}

    Use implode().

    echo implode(', ', $emails);

    All of these result:

    [email protected], [email protected], [email protected]
