我试图创建一个上传表单，用户可以通过3个输入上传3个文件/图像，但不幸的是，我没有足够的PHP知识，使其工作。
我使用的代码是:

我已经修改了您的代码，以便您可以从相同的输入类型上传多个图像
下面是你的index.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

<body>
<form action="upload-script.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload[]" id="fileToUpload" multiple="multiple">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
这将是你的upload-script.php文件
<?php
if (isset($_FILES['fileToUpload'])) {
$total = count($_FILES['fileToUpload']['name']);
$target_dir = "uploads/";
$uploadOk = 1;
// Check if image file is a actual image or fake image
for( $i=0 ; $i < $total ; $i++ ) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"][$i]);
if($check !== false) {
echo "<br>File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "<br>File is not an image.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"][$i]);
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"][$i], $target_file)) {
echo "<br>The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"][$i])). " has been uploaded.";
} else {
echo "<br>Sorry, there was an error uploading your file.";
}
}
}
?>
如果你只想上传3张图片，那么你可以根据需要修改$total变量为for循环。
同样，如果你需要3个单独的文件选择器，你可以检查修改后的代码。

您可以删除图像的isset检查，因为我已经制作了所需的所有图像。如果你从html中删除了必需的attr，那么你将需要isset checks
