从日志文件中的行中提取数字

I'm trying to convert a log file from:

我正在尝试转换日志文件:

2/20/2016 12:23:35 PM 80.0
2/20/2016 12:23:36 PM 76.7
2/20/2016 12:23:37 PM 75.0
2/20/2016 12:23:38 PM 75.4

To output only:

仅输出:

80.0
76.7
75.0
75.4

I have a pre-existing regex but it looks for the number with an A after and won't work for these logs. I know there is an EOL find by number but I can't seem to get it to work:

我有一个预先存在的正则表达式,但它会查找带有A after的数字,但不适用于这些日志。我知道有一个EOL按编号查找,但我似乎无法让它工作:

$regex = '/\d+$/'

Thanks!
