File is an image - image/jpeg.
文件是图像 - image/jpeg。 Warning: move_uploaded_file(uploads/IMG-20191002-WA0009.jpg): Failed to open stream: No such file or directory in C:\xampp\htdocs\resume\uploads\upload.php on line 46警告：move_uploaded_file(uploads/IMG-20191002-WA0009.jpg): 无法打开 stream: No such file or directory in C:\xampp\htdocs\resume\uploads\upload.php on line 46

Try an absolute path, by replacing:尝试绝对路径，通过替换：
$target_dir = "uploads/";
With something like:有这样的东西：
$target_dir = __DIR__ . '/uploads/';

The brackets are not set correctly and the form tag is missing.括号设置不正确，缺少表单标签。 All should be declared after the post event by clicking the submit button:应在发布事件后通过单击提交按钮声明所有内容：
$imageFileType = "";
$target_file = "";
if(isset($_POST["submit"])) {
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".<br>";
$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 ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
}
print "<FORM action='{$_SERVER['PHP_SELF']}' method='POST' enctype='multipart/form-data'>";
?>
<input type="file" name="fileToUpload"/>
<?php
print "<button type='submit' name='submit' style='width:100px;'>upload</button>";
print "</form>";
