Question

这是我的RE，我正在使用preg_match_all PHP，但我的结果并不准确 http://screencast.com/t/FPsoJkAT

#(\d+/\d+/\d+)|(\d+:\d+(AM|PM).*?[$]\d)#i

我正在获得额外的行（空行+ PM和AM），这些行应该被跳过

当我尝试使用RE实用程序测试它时，这是预期的结果。 http://screencast.com/t/RRteFlCD

有人请帮助我对此RE进行排序，以便将该确切结果与该实用程序生成的正确顺序相匹配。

RE不能正常工作

 preg_match_all("#(\d+/\d+/\d+)|(\d+:\d+(AM|PM).*?[$]\d)#i",$response,$result);

由于

Answer 1

preg_match_all()的结果数组是一个二维数组。 $result[0]是整个RE的所有匹配的数组。剩余的$result[i]是每个匹配中i捕获组的数组。

因此，出于您的目的，您关心的只是$result[0]。我对此进行了测试，它有47个元素。

此外，您应该将RE中的所有组更改为非捕获组，以避免首先生成所有这些无关的字符串。因此，每个(...)应为(?:...)。

print_r($result[0])打印：
