Question

给curr_date='2019/07/02'起作用时，但给curr_date='$b'起作用时

$b = date("Y-m-d",strtotime("yesterday"));

$sql = "SELECT * 
        FROM tbl_order_item 
        WHERE item_selected ='liquor' 
          and curr_time  BETWEEN '17:00:00' AND '24:00:00' 
          AND '1:00:00' 
          and item_name LIKE 'd%' 
          and curr_date='$b'";

Answer 1

在您的console.time('letCounter'); for (let letCounter = 0; letCounter < 10500; letCounter++) { console.log('letCounter', letCounter); } console.timeEnd('letCounter'); // 598.838134765625ms console.time('varCounter'); for (var varCounter = 0; varCounter < 10500; varCounter++) { console.log('varCounter', varCounter); } console.timeEnd('varCounter'); // 656.56494140625ms中使用-而不是$b = date("Y-m-d",strtotime("yesterday"));短划线

还修改BETWEEN子句，因为它仅采用两个值，例如

没有显示昨天的日期的正确日期
