我有以下PHP正则表达式:
@<tr[\s\S]*?<a class="b1"[\s\S]*?<em[^>]*>([^<]*)[\s\S]*?stars_small_([0-9].[0-9])@
我在本网站上使用的内容:
我收回了这些数据:
[1] => Array
(
[0] => AC/DC Live: Rock Band Track Pack
[1] => Ace Combat 6: Fires of Liberation
[2] => All-Pro Football 2K8
[3] => Alone in the Dark
[4] => Armored Core 4
[5] => Army of Two
[6] => Army of Two: The 40th Day
)
[2] => Array
(
[0] => 3.5
[1] => 2.5
[2] => 3.5
[3] => 3.5
[4] => 2.5
[5] => 3.5
[6] => 3.5
)

AC/DC Live: Rock Band Track Pack
Ace Combat 6: Fires of Liberation
Afro Samurai
Alan Wake
Aliens vs. Predator
All-Pro Football 2K8
Alone in the Dark
Amped 3
