Way does my for loop not complete the task if there are 4 emails it only 
process 3 emails through the foreach loop if there is 3 it only process 2

     #  Connect up
     $host ="domain.com";
     $port ="110";
     $mailtype = "pop3";
     $mailbox ="INBOX";
     $username ="[email protected]";
     $password ="boat1234";
    
     $conn = @imap_open("{" . $host . ":" . $port . "/" . $mailtype . 
"/notls}" . $mailbox, $username, $password);

$number=imap_num_msg($conn);
for($i = 1; $i <= $number; $i++) {
$file="C:\web\bouncehandler\eml\em$i";
imap_savebody($conn,$file,$i);


$file=file_get_contents("C:\web\bouncehandler\eml\em$i");
$multiArray = Bouncehandler::get_the_facts($file);

 $EMAIL = $the['recipient'];
foreach($multiArray as $the){
        switch($the['action']){
        case 'failed':
        $sql="UPDATE contacts SET emailstatus = 'Fatal-Bounced' WHERE 
emailaddress = '$EMAIL'";
        mysql_query($sql) or die("Invalid query: " . mysql_error());    
        break;
        case 'transient':
        $sql="UPDATE contacts SET emailstatus = 'Bounced' WHERE 
emailaddress = '$EMAIL'";
        mysql_query($sql) or die("Invalid query: " . mysql_error());
        break;
        case 'autoreply':
        $sql="UPDATE contacts SET emailstatus = 'Bounced' WHERE 
emailaddress = '$EMAIL'";
        mysql_query($sql) or die("Invalid query: " . mysql_error());
        break;
        default:
        //don't do anything
        break;
        }
    }

}
