안녕하세요

업로드가 도저히 되지 않아 인터넷에서 코드를 통째로 긁어서 쓰는데도 안되네여;;;

$target_dir = "data/evidence_img/";
$target_file = $target_dir . basename($_FILES["co_img"]["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["co_img"]["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["co_img"]["size"] > 5000000) {
    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["co_img"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["co_img"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

echo $_FILES["co_img"]["error"];
?>

이렇게 사용중인데

해당 폴더안에 이미지가 업로드 되지 않습니다

Sorry, there was an error uploading your file.

move_uploaded_file 여기서 처리가 되지 않아 위에 문구가 뜨는것 같은데

도저히 해결이 안되네요;;;

도움 부탁드립니다
