正则表达式-从字符串中拆分持续时间

Question

I currently have a string that is the title of a video. The string has annexed a time duration 00:00 . My regex currently is not splitting the tittle and duration. How can accomplish this?

print_r(preg_split('#(?<=\d)(?=[a-z])#', "The title of video 2:43"));

Result:

Array
(
    [0] => The title of video 2:43
)

Desired Result:

Array
(
    [0] => The title of video
    [1] => 2:43
)

Answer 1

You need to put [az] inside the positive lookbehind and \\d inside the positive lookahead. Put \\s inbetween those assertions so that it would split your input according to the in-between space character.

print_r(preg_split('#(?<=[a-z])\s(?=\d)#', "The title of video 2:43"));

Answer 2

为避免视频标题以数字结尾时出现过度匹配，您可以尝试使用以下代码：

print_r(preg_split('#(?<=[az])\\s(?=\\d{1,2}\\:\\d{2})#', "The title of video 2:43"));
