我寫了使用RegExr這個正則表達式。它捕捉到第5列（由分隔|），如果該行是匹配：

.*\|.*\|2010\|ford\|(.*)\|.*\|.*\|.*\|.*\|.*\|.*

當我運行就可以了preg_match_all，我得到這個錯誤：

preg_match_all() [<a href='function.preg-match-all'>function.preg-match-all</a>]: Unknown modifier '*'

我真的很好奇，爲什麼從b第四行數據中的ottom與其餘的語法突出顯示不同。 – Paulpro 2012-01-07 21:30:24

請確保您使用delimiters，它看起來像你想有一個case insensitive比賽還有：

$matches = array(); 
preg_match_all('/.*\|.*\|2010\|ford\|(.*)\|.*\|.*\|.*\|.*\|.*\|.*/i', $subject, $matches);

這很好 - 我接受了答案。這可能是我缺乏理解 - 但它應該返回兩個（F-250 SUPER DUTY PICKUP）時纔會返回一個匹配（F-350 SUPER DUTY PICKUP） – Avisra 2012-01-07 21:33:58

正則表達式表達不會與preg_match_all
