使用PHP的日子

如何解决使用PHP的日子

我在功课上有些卡住。我在医院住院日柜台，

记录输入的时间，日期，月份和年份，以及可能退出的日期和月份。

程序需要计算每月的住宿天数，并每月向他们收取费用，无论住宿月度是否已完成。

我非常受困，希望您能帮助我，我正在学习。

在脚本案例PHP中，它面向事件：

    $f = {folio};

//fechasdeenTrada

$check_sql3 = "SELECT id FROM HabitaAct WHERE folio = ".$f;
sc_lookup(ds_3,$check_sql3 );
$id1 = {ds_3[0][0]}; 
$check_sql4 = "SELECT diae FROM HabitaAct WHERE id = '".$id1."' ";
sc_lookup(ds_4,$check_sql4 );
$diae = {ds_4[0][0]}; // day
$check_sql2 = "SELECT mese FROM HabitaAct WHERE id = '".$id1."' ";
sc_lookup(ds_2,$check_sql2 );
$mese = {ds_2[0][0]}; // month
$check_sql5 = "SELECT Ane FROM HabitaAct WHERE id = '".$id1."' ";
sc_lookup(ds_5,$check_sql5 );
$Ane = {ds_5[0][0]}; // year
$check_sql6 = "SELECT tieme FROM HabitaAct WHERE id = '".$id1."' ";
sc_lookup(ds_6,$check_sql6 );
$tieme = {ds_6[0][0]}; // time

//exit date

$check_sql7 = "SELECT diaS FROM HabitaAct WHERE id = '".$id1."' ";
sc_lookup(ds_7,$check_sql7 );
$diaS = {ds_7[0][0]}; //day
$check_sql8 = "SELECT mesS FROM HabitaAct WHERE id = '".$id1."' ";
sc_lookup(ds_8,$check_sql8 );
$mesS = {ds_8[0][0]}; //month
$check_sql9 = "SELECT AnS FROM HabitaAct WHERE id = '".$id1."' ";
sc_lookup(ds_9,$check_sql9 );
$AnS = {ds_9[0][0]}; // year

$dientr = $diae;
$anac = $Ane;
$vd =$diae;
$ma = $mese;
$aa=  $Ane;
$an = $Ane; 
$limanu = 12;   


if( $mesS == $mese ){
    
    if($AnS==$Ane){
        
        $dmeig = $diaS - $diae;     
        
        echo $dmeig;
        
        if($diae=0){
            $diae=1;
        }
        
        echo $diae;
        
    }

}else{
