使用PHP上传图像并显示在单独的页面上

<form action="upload.php" method="POST" enctype="multipart/form-data">
  <input type="file" name="image">
  <input type="submit" value="Upload">
</form>

$targetDir = "uploads/"; // 上传目录
$targetFile = $targetDir . uniqid() . basename($_FILES["image"]["name"]); // 生成唯一文件名

if (move_uploaded_file($_FILES["image"]["tmp_name"], $targetFile)) {
  echo "Image uploaded successfully.";
} else {
  echo "Image upload failed.";
}

<?php
$imageFile = "uploads/" . $_GET["filename"]; // 获取图像文件名

if (file_exists($imageFile)) {
  echo "<img src='$imageFile' alt='Uploaded Image'>";
} else {
  echo "Image not found.";
}
?>

header("Location: image.php?filename=" . basename($targetFile));
exit;
