图像文件上传无法在wamp服务器上运行

Here is my HTML code "post.html"

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="upload" id="upload">
<input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

and here is my PHP code "upload.php"

<?php
target_dir = "upload/";
$target_file = $target_dir . basename($_FILES["upload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["upload"]["tmp_name"]);
if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
} else {
    echo "File is not an image.";
    $uploadOk = 0;
}
}
?>

and the result I am getting is

File is an image - image/jpeg.

There is no issue with execution of the files but the thing is whenever I uploads any file or image via html code the file does not comes up in the upload folder despite of successful execution of the code.

P.S I am using php7 on wampserver

    You should use below code line before your code line $uploadOk = 1;

    move_uploaded_file($_FILES["upload"]["tmp_name"], $target_file);

    Like:

    if (move_uploaded_file($_FILES["upload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["upload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
    

    While coping codes from some other sites please understand what is written in there and proceed. :-)

    $check = getimagesize($_FILES["upload"]["tmp_name"]); this line of code used to get size of image & do a size validation.

    Try this :   
    
    
     <?php
    
        // Check if image file is a actual image or fake image
        if(isset($_POST["submit"])) {
    
        target_dir = "upload/";
        $target_file = $target_dir . basename($_FILES["upload"]["name"]);
        $uploadOk = 1;
        $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
    
        $check = getimagesize($_FILES["upload"]["tmp_name"]);
        if($check !== false) {
            echo "File is an image - " . $check["mime"] . ".";
            $uploadOk = 1;
        } else {
            echo "File is not an image.";
            $uploadOk = 0;
        }
        }
        ?>
