Question

我正在从mysql数据库中检索我的图像并使用FPDF打印到我的PDF。我的问题是我希望我的MemImages从左到右排成一行而不是在彼此之下，以便在我打印时节省空间。可以请你请提前帮助和谢谢。我的代码如下。

$resultImage = mysql_query("SELECT * FROM DBImage WHERE projectSectionId = '$projectSectionId' AND userId = '$userId' AND date = '$date' AND time = '$time'");

while($runImage = mysql_fetch_assoc($resultImage))
{
$image = $runImage['image'];

if(empty($image)){
 } else {
 $pdf->Ln(2);
 $pdf->MemImage($image);
 $pdf->Ln(2);

 }
}

我终于得到了答案，也解决了其他将面临同样问题的开发人员。以下是我的答案。

$resultImage = mysql_query("SELECT * FROM DBImage WHERE projectSectionId =     '$projectSectionId' AND userId = '$userId' AND date = '$date' AND time = '$time'");

while($runImage = mysql_fetch_assoc($resultImage))
{
$array[] =$runImage;
$image = $runImage['image'];

$image_height = 45;
$image_width = 60;

//get current X and Y
$start_x = $pdf->GetX();
$start_y = $pdf->GetY();

if(empty($image)){
 }else{

// place image and move cursor to proper place. "+ 2" added for buffer
 $pdf->MemImage($runImage['image'],$pdf->GetX(), $pdf->GetY(),$image_width,$image_height);
 $pdf->SetXY($start_x + $image_width + 2, $start_y);

  }

}

使用FPDF和PHP水平对齐多个图像
