閱讀PHP中用於創建標籤的文件部分

Question

我有一個從MYSQL數據庫提取數據以創建標籤的文件。我在標籤結束處添加了一個字符串「BREAK」。我的數據文件看起來像這樣。

 
--------- Start File ------- 

BREAK 
Order: 10000 
NAME: XYZ 
Phone: XXX-XXX-XXX 

6 x ABC 
6 x Main ST 
6 x CITY 
6 x STATE 
6 x COUNTRY 

BREAK 
Order: 10001 
NAME: XYZ1 
Phone: XXX-XXX-XXX 

BMC 
MJ ST 
CITY 
STATE 
COUNTRY 

BREAK 
Order: 10002 
NAME: XYZ2 
Phone: XXX-XXX-XXX 

BMC 
MJ ST 
CITY 
STATE 
COUNTRY 

......more orders.. 

--------- End File ------- 

除了讀取3點或更多的塊和打印分開它們，對於第一塊，這是「6×」，我想從塊中刪除「6 x」和替代地存儲6作爲值在與unix上的lpr/print命令一起使用的變量中，用於打印6份副本。這不是一個大問題，我可以稍後解決它，但在php中閱讀這些塊並從它們創建3個或更多文件是我的要求。

這個小腳本會將您的訂單解析爲多維數組（請參閱下面的輸出）。 從這個數組中可以產生任何其他格式，比如將其插入數據庫，將其寫入其他文件或其他文件。

解析器

$orders = explode("BREAK", $fileContents); 
array_shift($orders); // only required if a "BREAK" is before the first order 
$ordersData = array(); 
foreach($orders as $order) { 

    if (preg_match("/Order: ([^\r\n]+)[\r\n]+NAME: ([^\r\n]+)[\r\n]+Phone: ([^\r\n]+)[\r\n]+(.+)/si", $order, $regs)) { 

     $items = preg_split("/[\r\n]+/", $regs[4], null, PREG_SPLIT_NO_EMPTY); 
     foreach ($items as &$item) { 

      if (preg_match("/(\d+) *?x *?(.+)/", $item, $regs2)) { 

       $item = array(
        'count' => $regs2[1], 
        'item' => $regs2[2] 
       ); 
      } else { 

       $item = array(
        'count' => 1, 
        'item' => $item 
       ); 
      } 
     } 

     $orderData = array(
      'order_no' => $regs[1], 
      'name' => $regs[2], 
      'phone' => $regs[3], 
      'items' => $items 
     ); 

     $ordersData[] = $orderData; 
    } 
}
