In php, convert the U.S. time to the custom function of Beijing Time. Beijing time _ PHP Tutorial

In php, the user-defined function of converting the U.S. time to Beijing time is shared. In php, the user-defined function of converting the U.S. time to Beijing time is shared. due to the time conversion used by the recent email system in Beijing time, we need to share the custom function of converting us time to Beijing time in php when we download emails from Google gmail.

The following code is directly used:

function datezhuanhuan($dateparams){$ccc=strtotime($dateparams);$date=date(‘Y-m-d');$bjtime=date(‘Y-m-d',$ccc);if($date==$bjtime){$sbjtime=date(‘Y-m-d H:i:s',$ccc);echo substr($sbjtime,11,5);}else{$sbjtime=date(‘Y-m-d H:i:s',$ccc);return substr($sbjtime,5,5);}}

Another 8-hour algorithm:

$bj_time = date ("Y-m-d H:i:s" , mktime(gmdate('H')+8,gmdate('i'),gmdate('s'),gmdate('m'),gmdate('d'),gmdate('Y')));
