如何return一个有效的日期时间格式？

Question

小四行代码return空值

 <?php 
   $date = "03-30-15";
   $time = "13:00";
   $zone = "America/Chicago";
   echo "String to time is: " . strtotime("$date $time $zone");
  ?>

Answer 1

strtotime 无法识别您传递的日期格式。需要采用 Y-m-d 格式：

来自Definition：

The function expects to be given a string containing an English date format

<?php 
   $date = "2015-03-30";
   $time = "13:00";
   $zone = "America/Chicago";
   echo "String to time is: " . strtotime("$date $time $zone");
  ?>
