如何在php页面上显示存储在数据库中的图像？

Question

我已将图像上传到我的数据库中的表中，并且我想使用php在页面上显示图像。 到目前为止它所做的只是显示一大堆丑陋的代码，我只是想知道如何改变它以回应实际图像？

Answer 2

试试下面的代码，部分内容来自这里

$filename = basename($file);
$file_extension = strtolower(substr(strrchr($filename,"."),1));

switch( $file_extension ) {
    case "gif": $ctype="image/gif"; break;
    case "png": $ctype="image/png"; break;
    case "jpeg":
    case "jpg": $ctype="image/jpg"; break;
    default:
}
header('Content-type:'.$ctype);
readfile($file);

Answer 3

$query = mysql_query('select image from table');

$row = mysql_fetch_assco($query);

$image = $row['image'];

echo "<img src='type:image/png;path/yourpath/'$image>";
