or 25m
or 1h
or 23s
. I need to convert that into time format of 00:00:00
.
将JIRA时间日志#h #m #s格式的持续时间转换为00:00:00

You can use a regex of
^(?:(?<hours>\d+)h\s*)?(?:(?<minutes>\d+)m\s*)?(?:(?<seconds>\d+)s\s*)?$
andsprintf
to make sure that zeroes are prepended:<?php function translateTime($timeString) { if (preg_match('/^(?:(?<hours>\d+)h\s*)?(?:(?<minutes>\d+)m\s*)?(?:(?<seconds>\d+)s\s*)?$/', $timeString, $matches)) { return sprintf( '%02s:%02s:%02s', (!empty($matches['hours']) ? $matches['hours'] : '00'), (!empty($matches['minutes']) ? $matches['minutes'] : '00'), (!empty($matches['seconds']) ? $matches['seconds'] : '00') ); } return '00:00:00'; } var_dump( translateTime('1h 20m 53s') ); //string(8) "01:20:53" var_dump( translateTime('20m 53s') ); //string(8) "00:20:53" var_dump( translateTime('53s') ); //string(8) "00:00:53" var_dump( translateTime('1h 30s') ); //string(8) "01:00:30" var_dump( translateTime('2h 3m') ); //string(8) "02:03:00"
While looking scary the regex is just a bunch of named capture groups:
\s
is a white space character (space, tab,,
\f
)\d
is a digit (0
