重置電子郵件主題中的訂單計數？

Question

我想發送一封電子郵件給客戶，每個訂單有一個訂單（＃1），訂單（＃2）等主題。在本月初，它會在發送電子郵件時重置爲訂單（＃1）？

好吧，讓我們看看

<?php 
    if(file_exists("id.txt")) { 
     $storedID = unserialize(file_get_contents('id.txt')); 
    } else { 
     $storedID = 1; 
     $toStoreID = serialize($storedID); 
     $handleID = fopen('id.txt','w+'); 
     fwrite($handleID, $toStoreID); 
    } 

    function sendEmail(){ 
     saveID(); 
     global $storedID; 
     echo "Order No (".$storedID.")"; 
     // $to = "customer@domain.com"; 
     // $subject = "Hello "Order No (".$storedID.")"; 
     // $body = "Hi,\n\nTahnks God For Stackoverflow"; 
     // if (mail($to, $subject, $body)) { 
     // echo("<p>Message sent!</p>"); // Put saveID(); here so failed emails dosen't count ! 
     // } else { 
     // echo("<p>Message delivery failed</p>"); 
     // } 
    } 

    function saveID(){ 
     global $storedID; 
     $today = date("d"); 
     if($today == 01 && file_exists("1st.txt")){ 
      $storedID = $storedID+1; 
      $toStoreID = serialize($storedID); 
      $handleID = fopen('id.txt','w+'); 
      fwrite($handleID, $toStoreID); 
     } else if($today == 01 && !file_exists("1st.txt")){ 
      fopen('1st.txt','w+'); 
      $storedID = 1; 
      $toStoreID = serialize($storedID); 
      $handleID = fopen('id.txt','w+'); 
      fwrite($handleID, $toStoreID); 
     } else { 
      $storedID = $storedID+1; 
      $toStoreID = serialize($storedID); 
      $handleID = fopen('id.txt','w+'); 
      fwrite($handleID, $toStoreID); 
     } 
     if ($today != 01 && file_exists("1st.txt")){ 
      unlink("1st.txt"); 
      $toStoreID = $toStoreID+1; 
     } 
     } 

    sendEmail(); 

?> 

我曾經寫過（4分鐘）代碼的最蠢行，反正會做的工作：/
