Saya cuma mau menambahkan saja.
Memang fungsi hash atau operator sama akuratnya, asal parameter
pada kedua fungsi tsb sama
Misalnya:
if hash("Test") == hash("Test ")
Akan menghasilkan false sebab ada trailing space.
Lebih aman sebelum di hash menggunakan
triming atau change case dulu.
Misalnya: $str = trim(strtolower($str))
