我正在使用fpdf创建pdf

我正在使用以下代码:

$pdf = new tFPDF();
$questions = $_POST['question'];
$count = count($questions);
$quests = "";
$pdf->AddFont('DejaVu','','DejaVuSansCondensed.ttf',true);
$pdf->SetFont('DejaVu','',14);

$pdf->SetTextColor(50,60,100);

$pdf->AddPage('P');


$pdf->SetFontSize(12);

for($i=1;$i<=$count;$i++)
{
    $qus_id = $questions[$i-1];
    $get_q = "select * from `SelleXam_question` where `id`='$qus_id'";
    $get_q =  $wpdb->get_results($get_q);
    $questf = "Quest $i : ".$get_q[0]->question;
            $pdf->Cell(0, 10, iconv('UTF-8', 'windows-1252', $questf)."\n");                                if($get_q[0]->image !=='')      {           $pdf->Ln();         $path = plugins_url();          $imagenurl = $path.'/roque/uploads/'.$get_q[0]->image;                      $pdf->Cell(0, 10, $pdf->Image($imagenurl,$pdf->GetX()+60, $pdf->GetY() + 5,50,50), 0, 0, 'L','');       }
    $questf = "Option 1 : ".$get_q[0]->op1;
    $pdf->Ln();
    $pdf->Cell(0, 10, $questf."\n");
    $questf = "Option 2 : ".$get_q[0]->op2;
    $pdf->Ln();
    $pdf->Cell(0, 10, $questf."\n");
    $questf = "Option 3 : ".$get_q[0]->op3;
    $pdf->Ln();
    $pdf->Cell(0, 10, $questf."\n");
    $questf = "Option 4 : ".$get_q[0]->op4;
    $pdf->Ln();
    $pdf->Cell(0, 10, $questf."\n");
    $pdf->Ln();
    $pdf->Ln();
}
$pdf=new tFPDF();
$questions=$_POST['question'];
$count=count($problems);
$quests=“”;
$pdf->AddFont('DejaVu','','DejaVuSansCondensed.ttf',true);
$pdf->SetFont('DejaVu','',14);
$pdf->SetTextColor(50,60100);
$pdf->AddPage('P');
$pdf->SetFontSize(12);
对于($i=1;$iget\u结果($get\u q);
$questf=“Quest$i:”.$get_q[0]->问题;
$pdf->Cell(0,10,iconv('UTF-8','windows-1252','questf.)“\n”);if($get_q[0]->image!=''){$pdf->Ln();$path=plugins\u url();$imagenurl=$path./roque/uploads/'.$get_q[0]->image;$pdf->Cell(0,10,$pdf->image($imagenurl,$pdf->GetX()+60,$pdf->GetY()+5,50,50),0,0,'L','';}
$questf=“选项1:”.$get_q[0]->op1;
$pdf->Ln();
$pdf->Cell(0,10,$questf.“\n”);
$questf=“选项2:”.$get_q[0]->op2;
$pdf->Ln();
$pdf->Cell(0,10,$questf.“\n”);
$questf=“选项3:”.$get_q[0]->op3;
$pdf->Ln();
$pdf->Cell(0,10,$questf.“\n”);
$questf=“选项4:”.$get_q[0]->op4;
$pdf->Ln();
$pdf->Cell(0,10,$questf.“\n”);
$pdf->Ln();
$pdf->Ln();
}
pdf已创建,但当我显示pdf时,会在该行末尾创建一个小框,pdf示例如下:

如何删除这些框?

删除字符串末尾的“\n”。单元格()不支持多行,tFPDF似乎不正确地将字符子集化,或将其替换为缺少的字形字符
