Question

我已经使用自定义时区在表格中保存了行。现在我想从这些表中检索数据，只需今天。

所以这就是我试过的

date_default_timezone_set('America/Los_Angeles'); 
$dt = new DateTime();
$today = $dt->format('Y-m-d'); //outputs 2015-12-07
$ok = mysqli_query($sqli,"SELECT * FROM `table` WHERE `date` = '$today'" );

我的行包含时间戳格式的日期，如2015-12-07 22:42:02

但我得到空洞的结果。

Answer 1

试试这个：

$ok = mysqli_query($sqli,"SELECT * FROM `table` WHERE DATE(date) = CURDATE()" );

根据时区转换时间：ConvertTimeZone

Answer 2

您应该在将日期传递给mysql之前将日期转换为时间戳：

date_default_timezone_set('America/Los_Angeles'); 
$dt = new DateTime();
$today = $dt->format('Y-m-d'); //outputs 2015-12-07

$ok = outputs("SELECT * FROM `table` WHERE DATE_FORMAT(date,'%Y-%m-%d')= $today" );

Answer 3

如果$ today =＆＃39; 2015-12-07 22：42：02＆＃39 ;;您的查询将给出结果。

$today='2015-12-07 22:42:02';
$ok = mysqli_query($sqli,"SELECT * FROM `table` WHERE `date` = '$today'" );

否则传递今天的日期和下一个日期并检索给定的值

$today='2015-12-07';
$next='2015-12-08';
$ok = mysqli_query($sqli,"SELECT * FROM `table` WHERE `date` >= '$today' and `date` <= '$next'  " );
