正在調試正則表達式時遇到問題。首先,該代碼(這是完整的文件...對不起缺乏換行符 - 見http://pastebin.com/h5CeiY5F的引擎收錄):正則表達式適用於某些服務器而非其他服務器
<?php
$matches = null;
$returnValue = preg_match('#" FirstDownType="[A-Z][0-9]+"/><Play PlayDescription="Penalty[^<]+/>#', '<Play DownDistanceYardline="3-1-GB 7" EarnedFirstDown="False" PlayDescription="(3:40) 71-C.Brown reported in as eligible. 28-M.Ingram left guard to GB 7 for no gain (94-J.Wynn; 95-H.Green)."/><Play DownDistanceYardline="4-1-GB 7" EarnedFirstDown="False" PlayDescription="(3:10) 9-D.Brees pass incomplete short left to 23-P.Thomas."/><Play Header="Green Bay Packers at 3:02"/><Play DownDistanceYardline="1-10-GB 7" EarnedFirstDown="False" PlayDescription="(3:02) 44-J.Starks right tackle to GB 11 for 4 yards (94-C.Jordan)."/><Play DownDistanceYardline="2-6-GB 11" EarnedFirstDown="False" PlayDescription="(2:26) 12-A.Rodgers pass deep right to 85-G.Jennings pushed ob at GB 33 for 22 yards (33-J.Greer)."

print_r($matches);
當我在幾個沙箱(如http://sandbox.onlinephpfunctions.com/或功能,在線運行此它返回:
Array ([0] => " FirstDownType="P17"/><Play PlayDescription="Penalty on NO-33-J.Greer, Defensive Pass Interference, declined."/>)
這是我正在尋找的預期輸出。
然而,當我在我的服務器上運行它(我已經測試了兩臺不同的服務器),我得到:
Array ([0] => " FirstDownType="P17"/>)
所有我能想到的是PHP 5.3.10之間的變化的preg_match (沙箱上的版本)和PHP 5.3.6(我們的版本),還是我們的Ubuntu版本配置錯誤?
我非常感謝任何幫助。謝謝!
如果您不能懶得添加這些換行符,我爲什麼要費心去從引擎收錄下載並找到了這個錯誤? – 2012-07-06 16:48:50
它確實匹配 - 但我必須查看源代碼才能看到完整匹配,因爲瀏覽器試圖將其解析爲HTML。另外,你真的不應該試圖通過REGEX解析標籤結構。使用DOM方法。 – Utkanos 2012-07-06 16:56:02
@Utkanos - 耐心等待+1。爲什麼不能有人問一個沒有水平滾動條的問題? – 2012-07-06 16:58:37
