PHP common library functions, php library functions

1. Time and date

• How to get the timestamp time()--the number of milliseconds since 1970

echo time();

• Date

echo date(<span>'</span><span>Y-m-d H:i:s</span><span>'</span>);

• The default time zone is obtained

echo date_default_timezone_get();

• The time obtained by default is inconsistent with the local computer time, and the corresponding time zone needs to be set

date_default_timezone_set('Asia/Shanghai'); //设置为上海的时区
echo date(<span>'</span><span>Y-m-d H:i:s</span><span>'</span>);

• Convert timestamp to date and present it

echo date(<span>'</span><span>Y-m-d H:i:s</span><span>'</span><span>,time());
echo </span><span>'</span><span><br/></span><span>'</span><span>;
echo date(</span><span>'</span><span>Y-m-d H:i:s</span><span>'</span>,time());
