Question

[Xaotik]

Приветствую, появился такой вопрос, имеется такой код, на загрузку файлов на гугл диск, но собственно как получать еще идентификатор файла которого загрузили?, если понадобится сохранить его

<?php

        echo "Go back and Select file to upload.";
        exit;
    }
    
    $file_tmp  = $_FILES["file"]["tmp_name"];
    $file_type = $_FILES["file"]["type"];
    $file_name = basename($_FILES["file"]["name"]);
    $path = "uploads/".$file_name;

    move_uploaded_file($file_tmp, $path);

    $folder_id = create_folder( "google-drive-test-folder" );

    $success = insert_file_to_drive( $path , $file_name, $folder_id);

    if( $success ){
        echo "file uploaded successfully";
    } else { 
        echo "Something went wrong.";
    }
}

// This will create a folder and also sub folder when $parent_folder_id is given
function create_folder( $folder_name, $parent_folder_id=null ){

    $folder_list = check_folder_exists( $folder_name );

    // if folder does not exists
    if( count( $folder_list ) == 0 ){
