[英]PHP image type application/png
出於某種原因,圖像類型在IE 7和Edge中顯示為“application / png”,在Chrome和Firefox中顯示為“image / png”。 我嘗試了幾種不同的圖像,jpeg做同樣的事情。 這是正常的嗎? 我應該包含一個或聲明來說明“application / png”嗎? 或者我做錯了什么?
if ((($screenshot_type == 'image/gif') || ($screenshot_type == 'image/jpeg') ||
($screenshot_type == 'image/pjpeg') || ($screenshot_type == 'image/png')) &&
(($screenshot_size > 0) && ($screenshot_size <= GW_MAXFILESIZE))) {
if ($_FILES['screenshot']['error'] == 0) {
// Move the file to the targe upload folder
$target = GW_UPLOADPATH . $screenshot;
if (move_uploaded_file($_FILES['screenshot']['tmp_name'], $target)) {
// Connect to the database
$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME)
or die('Unable to connect to databse');
// Write the data to the database
$query = "INSERT INTO guitarwars VALUES (0, NOW(), '$name', '$score', '$screenshot')";
mysqli_query($dbc, $query)
or die('Unable to complete query');
// Confirm success with the user
echo '<p>Thanks for adding your new high score!</p>';
echo '<p><strong>Name:</strong> ' . $name . '<br>';
echo '<strong>Score:</strong> ' . $score . '</p>';
echo '<img src="' . GW_UPLOADPATH . $screenshot . '" alt="Score image" /></p>';
echo '<p><a href="index.php"><< Back to high scores</a></p>';
// Clear the score data to clear the form
$name = "";
$score = "";
$screenshot = "";
mysqli_close($dbc);
}
else {
echo '<p class="error">Sorry, there was a problem uploading your screen shot image.</p>';
}
}
}
else {
echo '<p class="error">The screen shot must be a GIF, JPEG, or PNG image file no ' .
'greater than ' . (GW_MAXFILESIZE / 1024) . ' KB in size.<br>' . $screenshot_size . '<br>' . $screenshot_type . '</p>';
}
不同的瀏覽器和操作系統提供不同的mime類型。 您可能應該只在上傳的文件中使用http://php.net/getimagesize ,並使用IMG_PNG,IMG_JPG,IMG_GIF的案例打開$ getimagesizeresult [2],並自行應用適當的mime類型。
