推荐答案

我不知道您要执行的操作或执行操作的原因，因为您没有提供要更改为的完整详细信息还是为什么，但这是代码:

I don't know what you are trying to do or why you are doing it, as you haven't provided full details of what you want to change to or why, but here is the code :

<?php

$filename = "YOUR_FILE_NAME";

$target_dir = "photos/";
$target_file = $target_dir . $filename;
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

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;
   }
}

if (file_exists($target_file)) {
   echo "Sorry, file already exists.";
   $uploadOk = 0;
}

if ($_FILES["fileToUpload"]["size"] > 5000000) {
   echo "Sorry, your file is too large.";
   $uploadOk = 0;
}

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
   echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
   $uploadOk = 0;
}

if ($uploadOk == 0) {
   echo "Sorry, your file was not uploaded.";

} 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.";
   }
}

Echo "<b><button class=button onclick=location.href='images.html'>Click here to go back</button></b>";
?>
