我有以下文件（html和php），并且能够在服务器上运行php，但是单击“上传”后，我仍然收到“无法发布/fileUpload.php”的信息。
(Upload.html) （Upload.html）
<!DOCTYPE html>
<html>
<body>
<form action="fileUpload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<!--<input type="hidden" name="MAX_FILE_SIZE" value="500"> -->
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
(fileUpload.php) （fileUpload.php）
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";

Try to check the directory of fileUpload.php 尝试检查fileUpload.php的目录
And don't you want to have that moving process inside if(isset($_POST["submit"])) ? 而且，您是否不希望在if（isset（$ _ POST [“ submit”]）））内部进行移动？

Your code is working fine. 您的代码运行正常。 I am able to upload JPG, JPEG, PNG & GIF files. 我能够上传JPG，JPEG，PNG和GIF文件。 Please check your file structure. 请检查您的文件结构。
You can check the file destination path before upload by using file_exists() function 您可以使用file_exists（）函数在上传之前检查文件目标路径。
