在php preg正則表達式中匹配/省略多行

Question

當前在PHP preg_match語句中有一個正則表達式preg_match($regex,trim($searchText),$matches);

使用的正則表達式為（不帶分隔符）

Primary Redeemer: (?<name>.*), (?<phone>.*), (?<email>.*).*[.\r\n\s]*.*Valid Travelers:.*[.\r\n\s]*.*Valid Days: (?<date_in>\d{4}\/\d{2}\/\d{2}) - (?<date_out>\d{4}\/\d{2}\/\d{2}).*[.\r\n\s]*.*Item: (?<desc>.*) \/.*[.\r\n\s]*.*Voucher #: (?<voucher>\d+)  Itin. #:(?<itin>\d+)

對下面的$searchText運行就好了（如預期的那樣）

Booking
1 Travelers -- Vehicles: 1 (TBA),   
    Primary Redeemer: Joe Schmoe, 1 (555) 5555555, schmoe@joe.com
    Valid Travelers: Joe Schmoe, Sue Schmoe, Schmoe twins, 
    Valid Days: 2012/01/01 - 2012/02/02
    Item: Some Item Purchased - weekly 12345 / 
    Voucher #: 10835756  Itin. #:153244150897

返回$ matches數組中的各種命名元素。 但是，我們引入了一個新元素（航班），該元素在出發和返回時可能有1條或更多條線路。

克服一些障礙，以捕獲（和/或丟棄）可能出現的可變飛行信息行，而其余匹配/返回信息保持不變。

提前致謝。

不知道為什么. 不適用於您，但是[\\s\\S]* （或([\\s\\S]*)進行捕獲）應該可以抓取飛行塊：

<?php

  $regex = "/Primary Redeemer: (?<name>.*), (?<phone>.*), (?<email>.*).*[.\r\n\s]*.*Valid Travelers:.*[.\r\n\s]*.*Valid Days: (?<date_in>\d{4}\/\d{2}\/\d{2}) - (?<date_out>\d{4}\/\d{2}\/\d{2}).*[.\r\n\s]*[\s\S]*Item: (?<desc>.*) \/.*[.\r\n\s]*.*Voucher #: (?<voucher>\d+)  Itin. #:(?<itin>\d+)/";

  $searchText = <<<SEARCHTEXT_HEREDOC

SEARCHTEXT_HEREDOC;

  preg_match($regex,trim($searchText),$matches);

  echo "\n";
  foreach($matches as $match) {
    echo "  -> ".$match;
    echo "\n";
  }
  echo "\n";
?>
