yang akan menyebabkan/melempar kesalahan penguraian, seperti:
Di antara kesalahan lain seperti yang ditunjukkan dalam komentar saya dari kode asli Anda yang diposting.
Plus, Anda tidak menggunakan mysql_query dalam pembuatan tabel Anda.
Berikut adalah mysqli_ metode, di mana saya mengomentari kode asli Anda.
Sidenote:Anda menggunakan ID untuk kolom Anda di $query = "SELECT ID FROM " . $table; namun Anda membuat tabel dan kolom sebagai id dalam huruf kecil; kedua huruf harus cocok.
