php - Simple array foreach -

i'm sure simple ... can't seem figure out. need send email each of email addresses mentioning points. both emails have 36 points.

$emails = $usertools->weeklymail(); 

print_r:

array (     [0] => array         (             [0] => email1@gmail.com             [1] =>              [2] => 36         )      [1] => array         (             [0] => email2@gmail.com             [1] =>              [2] => 25         )  ) 

loop:

foreach($emails $email) {         $email = $email[0];         $subject = "you have ".$email[2]." points!!! !!!";         // message         $message = "hello\r\nyou have ".$email[2]." points .";         $helperclass->sendemail($email, $subject, $message); } 

your problem overwrite reference variable $email means $email[2] undefined.

change to:

foreach($emails $email) {         // $email = $email[0]; can't use $email[2] if $email overwritten         $subject = "you have ".$email[2]." points!!! !!!";         // message         $message = "hello\r\nyou have ".$email[2]." points .";         $helperclass->sendemail($email[0], $subject, $message); }
