本篇文章给大家带来的内容是关于php实现的时间帮助类 （代码示例），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
工作的过程中经常会遇到各种时间类的操作，因此封装了一个帮助工具类，提高代码的复用率
主要功能
根据相差的天数获取连续的时间段
/**

* @param string $dateFormat
* @return array
*/

for ($i=1;$i<=$diffDay;$i++){
$diff = $diffDay - $i;
$mday = date($dateFormat,strtotime("$today -$diff day"));
array_push($timeLabel,$mday);
}
//转化查询条件
$year = date('Y');
$startDay = str_replace('.','-',$timeLabel[0]);
$endDay = str_replace('.','-',$timeLabel[$diffDay-1]);
$startTime = strtotime($startDay." 00:00:00");
$endTime = strtotime($endDay." 23:59:59");
return [
'start_time' => $startTime,
'end_time' => $endTime,
'time_label' => $timeLabel,
