推荐答案

在mysql中一次插入多行需要在第一组数据后加逗号

to insert multiple rows at one time in mysql you need to add a comma after your first set of data

<?php
$con=mysqli_connect("example.com","mysqluser","mysqlpw","my_db");
if (mysqli_connect_errno())
  {
  echo "Failed to connect: " . mysqli_connect_error();
  }
mysqli_query($con,"INSERT INTO tablename(`uid`, `firstname`, `lastname`) VALUES ('15', 'James', 'thompson'),('25', 'Michael', 'Bagwell')");

mysqli_close($con); 
?> 

对于每个额外的行添加另一个 ,('id', 'first', 'last')

for each additional row add another ,('id', 'first', 'last')

由于您的请求发生了很大变化，这里更新了日期

since your request has quite changed here is an update for the dates

<?php
$startdate = strtotime($_POST["startdate"]);
$enddate = strtotime($_POST["enddate"]);
$sdate = date('Y-m-d',$startdate);
$edate = date('Y-m-d',$enddate);
$datediff = $sdate - $edate;
$countdays = floor($datediff/(60*60*24));
$query = "INSERT INTO tablename(`incdate`, `data1`, `data2`) VALUES ('" . $sdate . "', 'data', 'data')"

for ($i = 1; $i < $countdays; $i++) {
    $sdate->add(new DateInterval('P1D'));
    $query .= "('" . $sdate . "', 'data', 'data')"
}

$con=mysqli_connect("example.com","peter","abc123","my_db");
if (mysqli_connect_errno())
  {
  echo "Failed to connect: " . mysqli_connect_error();
  }
mysqli_query($con, $query);

mysqli_close($con); 
?> 

未测试但它应该可以工作，它会发现您输入的开始日期和结束日期之间的差异(以天为单位)，然后根据需要将每一天添加到查询中 - 一旦完成，它就会运行查询

not tested but it should work, it finds the difference in your inputted start and end date in days then adds each day to the query as appropriate - once completed it runs the query
