我写了使用RegExr这个正则表达式。它捕捉到第5列（由分隔|），如果该行是匹配：

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

当我运行就可以了preg_match_all，我得到这个错误：

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

我真的很好奇，为什么从b第四行数据中的ottom与其余的语法突出显示不同。 – Paulpro 2012-01-07 21:30:24

请确保您使用delimiters，它看起来像你想有一个case insensitive比赛还有：

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

这很好 - 我接受了答案。这可能是我缺乏理解 - 但它应该返回两个（F-250 SUPER DUTY PICKUP）时才会返回一个匹配（F-350 SUPER DUTY PICKUP） – Avisra 2012-01-07 21:33:58
