php -- 显示当前时间

默认为UTC

----- 002-time.php -----

 <!DOCTYPE html>
 <html>
 <head>
     <meta http-equiv="content-type" content="text/html; charset=utf-8">
     <title>一个PHP网页</title>
 </head>
 <body>
 <?php echo date("Y-m-d H-i-s", time()) ?>
 </body>
 </html>

显示警告

Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in D:\a\php\root\002-time.php on line 8

屏蔽警告

 <!DOCTYPE html>
 <html>
 <head>
     <meta http-equiv="content-type" content="text/html; charset=utf-8">
     <title>一个PHP网页</title>
 </head>
 <body>
 <?php @echo date("Y-m-d H-i-s", time()) ?>
 </body>
 </html>

显示错误：

Parse error: syntax error, unexpected 'echo' (T_ECHO) in D:\a\php\root\002-time.php on line 8

继续改原来@只作用于表达式

 <!DOCTYPE html>
 <html>
 <head>
     <meta http-equiv="content-type" content="text/html; charset=utf-8">
     <title>一个PHP网页</title>
 </head>
 <body>
 <?php echo @$cur_time = date("Y-m-d H-i-s", time()); ?>
 </body>
 </html>

换东八区

echo $cur_time = @date("Y-m-d H-i-s", time()+8*3600);
