This is echo output of image我将图像作为blob存储在数据库中,如下面的代码所示
<?php
// extract form values
if(isset($_POST['submit']))
{
$empnum = $_POST['emp_num'];
$lastname = $_POST['emp_lname'];
$firstname = $_POST['emp_fname'];
$initial = $_POST['emp_initial'];
$job = $_POST['job'];
$username = $_POST['emp_usr'];
$password = $_POST['emp_pass'];
$emp_bdate = $_POST['emp_bdate'];
$check = getimagesize($_FILES["image"]["tmp_name"]);
if($check !== false){
$image = $_FILES['image']['tmp_name'];
$imgContent = addslashes(file_get_contents($image));
插入员工详细信息
// build query
$qry = "INSERT INTO employee VALUES(" .
"'$empnum','$lastname','$firstname'," .
"'$initial','$job'," .
"'$username',PASSWORD('$password'),' $emp_bdate',' $imgContent')";
}
// execute query
$added = mysqli_query($dbconn,$qry);
这是为了检查是否有错误
// report results
if(trim($added) != "")
echo "Record added successfully." . "<br>";
else
{
echo "ERROR: Record could not be added<br>" .
mysqli_error($dbconn);
}
// close connection
mysqli_close($dbconn);
}
?>
我没有显示图像,但正在输出以下图像
$imageData =base64_encode($line['image']);
echo "<img src='data:image/jpeg;base64,$imageData' height='200' width='250' alt=''>'"

尝试使用此代码,确保您的图片扩展名始终为“ jpeg”,或者需要使其动态化。
<?php
$imageData = base64_encode($line['image']);
echo "<img src='data:image/jpeg;base64,$imageData' height='200' width='250'>";
?>

不要将图像文件另存为base64,您只需将图像目录保存在其中。因此,当您调用图片时,只需将网址调用到图片目录位置即可。
