我使用RegExr编写了这个正则表达式。它捕获第5列（由|分隔），如果该行匹配：

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

当我在其上运行preg_match_all时，我收到此错误：

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

答案 0 :(得分：3)

请务必使用delimiters，看起来您还想要case insensitive匹配：

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