What is the significance of using the complete file path instead of just the file name when working with uploaded files in PHP?

When working with uploaded files in PHP, using the complete file path instead of just the file name is important because it ensures that the file is being accessed from the correct location on the server. This helps prevent any potential security vulnerabilities or file manipulation issues. By using the complete file path, you can ensure that the file is being accessed from the intended directory, providing a more secure and reliable method for handling uploaded files. 

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

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