What are the best practices for handling image uploads and storage in a PHP application connected to an Oracle database?

When handling image uploads and storage in a PHP application connected to an Oracle database, it is important to properly sanitize and validate user input to prevent security vulnerabilities. Additionally, it is recommended to store images in a designated directory on the server and save the file path in the database for retrieval. Utilizing PHP's file handling functions and Oracle's BLOB data type can help efficiently manage image uploads and storage. 

// Sample code for handling image upload and storage in PHP connected to an Oracle database

// Validate and sanitize image upload
if(isset($_FILES['image'])){
    $file_name = $_FILES['image']['name'];
    $file_tmp = $_FILES['image']['tmp_name'];
    
    // Move uploaded file to designated directory
    move_uploaded_file($file_tmp, 'uploads/' . $file_name);
    
    // Save file path to Oracle database
    $file_path = 'uploads/' . $file_name;
    $query = "INSERT INTO images (file_path) VALUES (:file_path)";
    $stmt = oci_parse($conn, $query);
    oci_bind_by_name($stmt, ':file_path', $file_path);
    oci_execute($stmt);
    
    echo "Image uploaded and stored successfully.";
}
