PHP Convert UNIX Timestamp UTC Time (TZ Format) Standard Time Methods to convert UNIX UTC GMT time and local time to each other

In PHP programming, we often encounter time in various formats

For example:

unix timestamp: 1547740800

UTC time: 2019-1-18T00:00:00Z

Standard time: 2019-1-18 00:00:00

The above three time formats all represent 0:00:00 on January 18, 2019. How to convert these three time formats in PHP? Here I will teach you

1. Convert UNIX to UTC

echo date('Y-m-dTH:i:sZ', 1547740800);
//输出:2019-1-18T00:00:00Z

or

echo date('c',1547740800);
//输出:2019-1-18T00:00:00Z+02:00

2. Convert UNIX to standard time

echo date('Y-m-d H:i:s', 1547740800);
//输出:2019-1-18 00:00:00

3. Convert UTC Standard time

 $utc='2019-1-18T00:00:00Z';
   $unix= str_replace(array('T','Z'),' ',$utc);
   echo $unix;
  //输出:2019-1-18 00:00:00

4. Convert UTC to UNIX timestamp

$utc='2019-1-18T00:00:00Z';
   $time= str_replace(array('T','Z'),' ',$utc);
   $unix=strtotime($time);
   echo $unix;
  //输出:1547740800

5. Convert standard time to UNIX timestamp

$time='2019-1-18 00:00:00';
   $unix=strtotime($time);
   echo $unix;
   //输出:1547740800

6. Convert standard time to UTC time

$time='2019-1-18 00:00:00';
   $unix=strtotime($time);
   $utc=date('Y-m-dTH:i:sZ', $unix);
   echo $utc;
   //输出:2019-1-18T00:00:00Z
