Question

I got the follow error:

verzend mail naar t met attachment: e
verzend mail naar w met attachment: w
verzend mail naar r met attachment: a
verzend mail naar w met attachment: w
verzend mail naar r met attachment: a
verzend mail naar w met attachment: w

Notice: Uninitialized string offset: 0 in /variables.php on line 248

Notice: Uninitialized string offset: 1 in /variables.php on line 248
verzend mail naar met attachment: 

This is my code:

<?php
    $emailString = '[e-mail];www.test.nl^[e-mail];www.test2.nl^[e-mail];www.test3.nl^';

    $user = explode("^", $emailString); // urls 
    foreach($user as $a_user) {

        $user2 = explode(";", $a_user); // emails
        $a_mailing = array();

        foreach ($user2 as $a_user) {
            $a_mailing[$a_user[0]][] = $a_user[1];
        }   

       foreach($a_mailing as $key => $a_values) {
            foreach($a_values as $value) {
                echo 'verzend mail naar ' . $key . ' met attachment: ' . $value . '<br />';
            }
        }
    }
?>

Can anyone help me??

Answer 1

The issue is that $a_user in the first loop is a string. For example.. in the first iteration the $a_user variable contains this: “[e-mail];www.test.nl”;

From what I can see, I believe you are just trying to use the email address as a key and the url as a value so you dont need to use a second loop for that. You can replace:

foreach ($user2 as $a_user) {
    $a_mailing[$a_user[0]][] = $a_user[1];
} 

with:

$a_mailing[$user2[0]][] = $user2[1];
