   oldYearValue= currentYear-i;
  
  if(oldYearValue != new Date().getFullYear()){
    
  
     $('#select1').append('<option value='+oldYearValue+'>'+oldYearValue+'</option>');
  }
  if (i==0){
    
    for (var j = 0; j <= 5; j++) {
   
   newYearValue= currentYear+j;
     $('#select1').append('<option value='+newYearValue+'>'+newYearValue+'</option>');
}

在PHP中可能对您有帮助

<div class="col-12">
 <select class="form-select bg-light border-0">
         <option disabled selected>Years</option>
         <?php
         for ($i = 4; $i >= 0; $i--) {
           $year_= date('Y', strtotime("-$i year"));
           echo '<option value="'.$year_.'">'.$year_.'</option>';
         }?>
  </select>
