把HH:MM:SS格式的時間字符串轉換成秒數,可以使用date_parse函數解析具體的時間信息。
<?php
$time = '21:30:10';
$parsed = date_parse($time);
$seconds = $parsed['hour'] * 3600 + $parsed['minute'] * 60 + $parsed['second'];
echo $seconds;
?>
更詳細的例子
轉換成多少天/多少小時/多少分
function get_stay_time($timestamp, $is_hour = 1, $is_minutes = 1)
{
$CI =& get_instance();
if(empty($timestamp) || $timestamp <= 60) {
return false;
}
$time = time();
$remain_time = $time - $timestamp;
$day = floor($remain_time / (3600*24));
$day = $day > 0 ? $day.'天' : '';
$hour = floor(($remain_time % (3600*24)) / 3600);
$hour = $hour > 0 ? $hour.'小時' : '';
if($is_hour && $is_minutes) {
$minutes = floor((($remain_time % (3600*24)) % 3600) / 60);
$minutes = $minutes > 0 ? $minutes.'分' : '';
return $day.$hour.$minutes;
}
if($hour) {
return $day.$hour;
}
return $day;
}
