How can the issue of opening a file stream be resolved when using an input field of type "file"?

Issue: When using an input field of type "file" in HTML to upload a file, the file stream needs to be opened in PHP to read the contents of the uploaded file. This can be achieved by using the "fopen" function in PHP with the "r" mode to open the file stream. PHP code snippet: 

if(isset($_FILES['file'])) {
    $file = $_FILES['file']['tmp_name'];
    
    $fileStream = fopen($file, 'r');
    
    // Read the contents of the file stream here
    
    fclose($fileStream);
}
