Newbie using gnuchess

Hari ini tepatnya dini hari tadi, pas ketika lagi bete ngoding akhirnya browsing-browsing ga jelas vi Chromium tapi ternyata internet sangat lambat, karena koneksi IX dari kantor lagi kacau, buat ngebuka satu google.com aja lama banget, tapi yang aneh buka situs Indonesia juga lambat banget, yah.. tingkat keboringan jadi meningkat gara-gara ini

Akhirnya buat ngilangin bosen dari browsing ane main catur, pas nyari di Games ternyata belum ada tuh caturnya,, dengan berat hati (karena koneksi lagi kacau) akhir nginstall via apt-get meski agak lama akhirnya gnuchess sukses dengan gemilang terinstall.

Seperti biasa ketika jalanin aplikasi ane pencet ALT+F2 trus ketik gnuchess  dan dengan penuh semangat kelingking ane menekan Enter and... ga ada muncul apa-apa?? Trus coba lagi dengan metode yang sama, ternyata ga muncul apa-apa juga... Ok its time to googling.. ternyata gnuchess itu cuma engine nya doang, kalaupun ada tampilan ini juga sangat-sangat sederhana sekali.. like this screenshot

php: array_key_exists or isset

and this is code for the which array_key_exists i look in the php source code.

In my mind, array_key_exists is like that :)

boolean array_key_exists (key, arrayName) {
    return isset(arrayName[key]);
}

Using keyword as method in PHP

As we know, we can't use keyword like if, while in common language programming as function, method or variables, neither does in PHP Programming.

Alasan utama adalah performance dari skrip yang dibuat, hal ini bertujuan untuk membandingkan fungsi yang akan digunakan sehingga losstime bisa dikurangi. Dalam pemrograman PHP bisa dilakukan dengan mengambil nilai fungsi microtime(), tentu saja ditambahkan parameter boolean bernilai true agar nilai yang dikembalikan adalah float, karena jika tidak ada parameter yang diberikan maka nilai return dari fungsi ini adalah string.
