Incorrect results showing on Date conversion in php

问题

$testTime   =   strtotime("2016-03-03 07:40:45 pm");    
echo "final=".$final        =   DATE("Y-m-d H:i",$testTime);//2016-03-03 19:40

Showing the correct out put But when ever I tried to change the hour to Zero

$testTime   =   strtotime("2016-03-03 00:30:45 am");    
echo "final=".$final        =   DATE("Y-m-d H:i",$testTime);//1970-01-01 01:00

Incorrect values are showing.
Any idea?

回答1:

you are using am/pm with 24 hours format. am/pm should be with 12 hr

12 hour = 12:30:45 AM

$testTime   =   strtotime("2016-03-03 12:30:45 am");
$final      =   DATE("Y-m-d H:i",$testTime);//1970-01-01 01:00

24 hour = 00:30:45

$testTime   =   strtotime("2016-03-03 00:30:45");
$final      =   DATE("Y-m-d H:i",$testTime);//1970-01-01 01:00
