目前在 PHP preg_match 语句中有一个正则表达式 preg_match($regex,trim($searchText),$matches);

使用的正则表达式是（不带分隔符）

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+)

符合以下$searchText条件就好了（如预期的那样）

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 数组中的各种命名元素。但是，我们引入了一个新元素（航班），它可能在出发和返回时都有 1 条或更多条线路。

在捕获（和/或丢弃）可能出现的可变飞行信息行时遇到一些障碍，同时保持匹配/返回的其余部分完好无损。

提前致谢。

不知道为什么.不适合你，但[\s\S]*（或([\s\S]*)捕获）应该可以抓住飞行块：

<?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";
?>

结果：
