php - 解析 Skype 日志

Question

我需要解析 Skype 日志，获取所有通话时长并将它们相加，找出整个聊天记录的通话总时长。

示例:

[3/12/2012 11:36:44 AM] * 通话结束，持续时间 21:33 *

我想我需要使用带有正确正则表达式的 preg_match。如果可以同时将实际时间戳存储在数组中，那就更好了。

我认为我真正难过的是仅获取通话时长所需的实际正则表达式规则。

Answer 1

试试这个

(?i)\[(?P<time_stamp>[^[]+)\]\s*[*]\s*[a-z ,]+(?P<duration>(?:\d{2}:?){2,3})\s*[*]

(?i)               # Match the remainder of the regex with the options: case insensitive (i)
