While uploading an image with php, deleting the old image at the same time. (unlink)

first of all I'm sorry for using Google translate. I don't know much about these things. As a result of my Google research, I learned that I could delete the old image with unlink, but it didn't work. The code below loads an image into the database and file but does not delete the old image.

if ($_FILES['fotodort']['tmp_name'] != "")
{
    $boyutdort = $_FILES['fotodort']['sizedort'];
    $tip = mime_content_type($_FILES['fotodort']['tmp_name']);
    if($tip!="image/jpeg" && $tip!="image/jpg" && $tip!="image/png" && $tip!="application/pdf"){
        echo 'Dosya Jpeg veya Png yada Gif , PDF formatında olmalı';
    }elseif ($boyutdort > (1024 * 1024 * 30)) {
        echo 'Dosya 10MB den büyük olamaz.';
    } else {
        $tipdort = $_FILES['fotodort']['type'];
        $isimdort = $_FILES['fotodort']['name'];
        $uzantidort = explode('.', $isimdort);
        $uzantidort = $uzantidort[count($uzantidort) - 1];
        $randomdort = rand();
        $dosyadort = $_FILES['fotodort']['tmp_name'];
        $foto_urldort = $randomdort . "." . $uzantidort;
        copy($dosyadort, '../assets/images/admin-img/' . $foto_urldort);
        if (file_exists("../assets/images/admin-img/".$foto_urldort)) {
            unlink("../assets/images/admin-img/".$foto_urldort);
        }
        $settings = $dbh->prepare("UPDATE general_settings SET foto_dark = '".$foto_urldort."' WHERE id=1 ");
        $settings->execute();
    }
}

I tried to integrate the code I found from a different system into this code, but I could not succeed.

       if (file_exists("../assets/images/admin-img/".$fotodort)) {
            unlink("../assets/images/admin-img/".$fotodort);
        }

I would be grateful if you could help with this. There are more than 20 image upload fields. I will update all of them with the method I will learn from you. It will also work if you teach a different code structure that will do the same operations.

I found a solution and the system works fine. Do you check if block sequences are in the right place?

if ($_FILES['fotodort']['tmp_name'] != "") {
      $boyutdort = $_FILES['fotodort']['sizedort'];
      $tip = mime_content_type($_FILES['fotodort']['tmp_name']);
      if($tip!="image/jpeg" && $tip!="image/jpg" && $tip!="image/png" && $tip!="application/pdf"){
        echo 'Dosya Jpeg veya Png yada Gif , PDF formatında olmalı';
      }elseif ($boyutdort > (1024 * 1024 * 30)) {
       echo 'Dosya 10MB den büyük olamaz.';
     } else {
      $tipdort = $_FILES['fotodort']['type'];
      $isimdort = $_FILES['fotodort']['name'];
      $uzantidort = explode('.', $isimdort);
      $uzantidort = $uzantidort[count($uzantidort) - 1];
      $randomdort = rand();
      $dosyadort = $_FILES['fotodort']['tmp_name'];
      $foto_urldort = $randomdort . "." . $uzantidort;
      copy($dosyadort, '../assets/images/admin-img/' . $foto_urldort);
      echo " 
      <script>
      const Toast = Swal.mixin({
        toast: true,
        position: 'top-end',
        showConfirmButton: false,
        timer: 6000,
        timerProgressBar: true,
        didOpen: (toast) => {
          toast.addEventListener('mouseenter', Swal.stopTimer)
          toast.addEventListener('mouseleave', Swal.resumeTimer)
        }
        })

        Toast.fire({
          icon: 'success',
          title: 'Başarı ile güncellendi.'
          })
          </script> ";
          $settings = $dbh->prepare("UPDATE general_settings SET foto_dark = '".$foto_urldort."' WHERE id=1 ");
          $settings->execute();
          
            if (file_exists('../assets/images/admin-img/'.$_POST['eskiresimsil']) && $dosyadort) {
                unlink('../assets/images/admin-img/'.$_POST['eskiresimsil']);
            }
        
         }
 }

I wrote the old image name before the submit button:

<input type="hidden" name="eskiresimsil" value="<?=$ayar['foto_dark'];?>">

try this

if ($_FILES['fotodort']['tmp_name'] != "") {
    $size = $_FILES['fotodort']['sizedort'];
    $type = mime_content_type($_FILES['fotodort']['tmp_name']);
    if($type!="image/jpeg" && $type!="image/jpg" && $type!="image/png" && $type!="application/pdf"){
        echo 'Dosya JPEG/JPG, PNG, yada PDF formatında olmalı';
    }elseif ($boyutdort > (1024 * 1024 * 30)) {
        echo 'Dosya 10MB den büyük olamaz.';
    } else {
        $dosyadort = $_FILES['fotodort']['tmp_name'];
        $name = rand().$_FILES['fotodort']['extension'];
        copy($dosyadort, '../assets/images/admin-img/' . $name);

        $upload = $dbh->prepare("UPDATE general_settings SET foto_dark ='".$foto_urldort."' WHERE id=1");
        $upload->execute();

         if (file_exists("../assets/images/admin-img/".$fotodort) && $dosyadort) {
            unlink("../assets/images/admin-img/".$fotodort);
         }
    }
}
