problem with for loop

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 ="bounce@domain.com";
    $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;
       }

} }
