¿Cómo cargar una imagen en el servidor localhost mientras la ruta está almacenada en la base de datos mysql?

También tuve este problema, aunque lo descubrí. Haré un recorrido rápido sobre cómo cargar un archivo en un directorio y guardar la ruta en MySQL, puede hacer varias consultas después de ver la consulta inicial, de esa manera puede soltar y eliminar el archivo como desee . Aquí va:

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:<br>

    <input type="file" name="fileToUpload" id="fileToUpload"><br><br>


    <input type="submit" value="Upload Image" name="submit">
</form>

    <?php $target_dir = "ANY_DIRECTORY_YOU_LIKE/PICTURES/";
    $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"] > 1000000) {
        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.";
            $pictureName = "ANY_DIRECTORY_YOU_LIKE/PICTURES/". basename( $_FILES["fileToUpload"]["name"]);



$servername = "localhost";
$username = "MySQL_USERNAME";
$password = "MySQL_PASSWORD";
$dbname = "MySQL_DATABASE_NAME";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "UPDATE TableName SET myPicture='$pictureName' WHERE email='$myEmail' AND password='$myPassword'";
// Make Sure to tell MySQL which user you want to update which means setting the variable $myEmail and $myPassword accordingly

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

$conn->close();





    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

¡Que te diviertas! Ah, y mi base de datos usa VarChar para las imágenes. Si quieres ser creativo y descubrir otra forma, adelante.
