PHP原生代码生成pdf---解决中文乱码问题

github地址

尝试了使用composer下载FPDF或者FPDI，但是无法解决中文乱码问题。只有使用这个github上的中文包才可以，那俩没必要下。

直接上代码(这里并没有使用任何框架)

	require('./fpdf/chinese.php');//生成pdf$pdf = new PDF_Chinese();$pdf->AddPage();$pdf->AddGBFont('songti');$pdf->SetFont('songti', '', 13);$pdf->Write(0, iconv("UTF-8", "gbk", "客户名:" . $_POST['customer_name']) . " ");$pdf->Ln(8);$pdf->Write(0, iconv("UTF-8", "gbk", "客户手机号:") . $_POST['tel'] . " ");$pdf->Ln(8);$pdf->Write(0, iconv("UTF-8", "gbk", "客户地址:" . $_POST['address']) . " ");$pdf->Ln(8);//换行$pdf->Write(0, iconv("UTF-8", "gbk", "面积:") . $_POST['area'] . " ");$pdf->Ln(8);$pdf->Write(0, iconv("UTF-8", "gbk", "客户等级:" . $level_name) . " ");$pdf->Ln(8);$pdf->Write(0, iconv("UTF-8", "gbk", "备注:" . $_POST['remark']) . " ");$pdf->Ln(8);//换行$pdf->Write(0, iconv("UTF-8", "gbk", "客厅图片:"));$pdf->Ln(5);$pdf->Image($_POST['room_pic1'], $pdf->GetX(), $pdf->GetY(), 100, 80, 'JPEG');$pdf->Ln(83);$pdf->Image($_POST['room_pic2'], $pdf->GetX(), $pdf->GetY(), 100, 80, 'JPEG');$pdf->Ln(83);$pdf->Image($_POST['room_pic3'], $pdf->GetX(), $pdf->GetY(), 100, 80, 'JPEG');$pdf->AddPage();$pdf->Ln(3);$pdf->Write(0, iconv("UTF-8", "gbk", "客厅备注:" . $_POST['room_remark']));//换行$pdf->Ln(5);$pdf->Write(0, iconv("UTF-8", "gbk", "卧室图片:"));$pdf->Ln(3);$pdf->Image($_POST['bedroom_pic1'], $pdf->GetX(), $pdf->GetY(), 100, 80, 'JPEG');$pdf->Ln(83);$pdf->Image($_POST['bedroom_pic2'], $pdf->GetX(), $pdf->GetY(), 100, 80, 'JPEG');$pdf->Ln(83);$pdf->Image($_POST['bedroom_pic3'], $pdf->GetX(), $pdf->GetY(), 100, 80, 'JPEG');$pdf->Ln(3);$pdf->AddPage();$pdf->Write(0, iconv("UTF-8", "gbk", "卧室备注:" . $_POST['bedroom_remark']));$pdf->Output('F', 'example.pdf');
