如何解决SQL中的多次插入，数据库中的经常性费用插入
用户增加收入或费用。如果他将其归类为经常性交易，则他从包含（每周，每两周，每月等）的frequency_dropdown中选择。用户还输入开始日期和结束日期。
我想根据选择的频率增加日期。例如，如果我有每周，那么我想使用“修改”功能添加+1周，但是此功能未对日期进行任何修改，并且卡在了连续的if循环中。
我的第一个查询成功，并且将数据插入数据库中，但是循环内的查询不起作用，因为日期没有按照所选频率增加。
//db query is done here.
$sde=$_POST['startdateexpense'];
$ede=$_POST['enddateexpense'];
$dt = new DateTime(str_replace("-","/",$sde));
$dtUntil = new DateTime(str_replace("-",$ede ? $ede : date("m-d-Y")));
$modifiers=[
"Annually"=>"+1 year","Daily"=>"+1 day","Weekly"=>"+1 week","Fort-nightly"=>"+2 weeks","Monthly"=>"+1 month","Quarterly"=>"+4 months","Semi-Annually"=>"+6 months","Annually"=>"+1 year"
];
$modifier=$modifiers[$ExpenseFrequency];
$dt->modify($modifier);
if($dt <= $dtUntil){
$dt->modify($modifier);
//db query is done here.
}
INPUT Expected and actual output
有人可以帮我解决这个问题吗？

$ modifier = $ modifiers [$ ExpenseFrequency];
这部分需要放在[]大括号内。
应该对$ sde进行格式化，以将其插入数据库。
$modifiers=[
"Annually"=>"+1 year","Daily"=>"+1 day","Weekly"=>"+1 week","Fort-nightly"=>"+2 weeks","Monthly"=>"+1 month","Quarterly"=>"+4 months","Semi-Annually"=>"+6 months",];
//$dt->modify($modifier);
if($sde <= $ede){
$modifier= $modifiers[$ExpenseFrequency];
