While Loops syntax untuk while loop: while (expression) { code to execute; } contoh while loop yang menghitung sampai 10 script------------- <?php $num = 1; while ($num <= 10){ print "Number is $num<br />\n"; $num++; } print 'Done.'; ?> script------------- menghasilkan:

Number is 1 Number is 2 Number is 3 Number is 4 Number is 5 Number is 6 Number is 7 Number is 8 Number is 9 Number is 10 Done. script nya akan me-loop sampai 10 dan script $num++ bertambah 1 2. For Loops syntax untuk For Loops adalah for (initialization expression; test expression; modification expression){ code that is executed; } contoh script untuk for loop: script------------- <?php for ($num = 1; $num <= 10; $num++) { print "Number is $num<br />\n"; } ?> script------------- menghasilkan: Number is 1 Number is 2 Number is 3 Number is 4 Number is 5 Number is 6 Number is 7 Number is 8

Number is 9 Number is 10 3. Menghentikan sebuah Loop contoh Menghentikan sebuah Loop untuk menghindari Loop: script------------- <?php $counter = -3; for (; $counter < 10; $counter++){ // Check for division by zero if ($counter == 0){ echo "Stopping to avoid zero."; break; } echo "100/$counter<br />"; } ?> script------------- menghasilkan: 100/-3 100/-2 100/-1 Stopping to avoid division by zero. *dia akan loop sampai fungsi if dan karena ada script break, maka proses akan berhenti *script ini suatu saat akan berguna "Trust me" 4. continue Statements penggunaan continue selain break script------------- <?php

$counter =- 3; for (; $counter < 10; $counter++){ // Check for division by zero if ($counter == 0){ echo "Skipping to avoid zero.<br />"; continue; } echo "100/$counter<br />"; } ?> script------------- menghasilkan: 100/-3 100/-2 100/-1 Skipping to avoid zero. 100/1 100/2 100/3 100/4 100/5 100/6 100/7 100/8 100/9 *dia akan loop sampai fungsi if dan karena ada script continue, maka proses akan berhenti mengganti angka 0 menjadi Skipping to avoid zero, lalu looping akan di lanjutkan kembali Membahas Fungsi include - include_once - require - include() - include_once() - require() Fugnsi di atas berguna untuk menggabungkan file PHP atau bukan PHP kedalam file PHP +++ include()

sebagai contoh head.php ----- <?php echo "selamat datang di website ku<br>"; ?> ----- body.php ----- <?php include 'head.php'; echo "<br>Ini adalah contant atau isi dari website ku<br>"; ?> ----- hasilnya: selamat datang di website ku Ini adalah contant atau isi dari website ku +++ include_once() "include_once()" berfungsi untuk membatasi fungsi include cuma untuk satu kali saja contoh jika tidak menggunakan "include_once()": body.php ----- <?php include 'head.php'; include 'head.php'; include 'head.php'; echo "<br>Ini adalah content atau isi dari website ku<br>"; ?> ----- hasilnya: selamat datang di website ku selamat datang di website ku selamat datang di website ku Ini adalah content atau isi dari website ku contoh jika menggunakan "include_once()": body.php ----- <?php include_once 'head.php'; include_once 'head.php'; include_once 'head.php'; echo "<br>Ini adalah contant atau isi dari website ku<br>"; ?>

----- hasilnya: selamat datang di website ku Ini adalah content atau isi dari website ku +++ require() fungsi ini tidak jauh beda dengan fungsi "include()" alias sama, jadi kita loncati saja fungsi ini Sekarang untuk sisi security/keamanan dari fungsi include() kenapa?? ya.. karena fungsi ini paling banyak di manfaatkan hacker .... 1. include hanya file yang berasal dari server anda saja... caranya: body.php ------ <?php include($_SERVER['DOCUMENT_ROOT'].'/head.php'); ?> ------ jika file head.php ada di root atau tidak dalam folder body.php ------ <?php include_once($_SERVER['DOCUMENT_ROOT'].'/head.php'); ?> ------ body.php ------ <?php require_once($_SERVER['DOCUMENT_ROOT'].'/head.php'); ?> ------ Untuk melihat dimana posisi file php anda, anda bisa gunakan: <?php echo $_SERVER['DOCUMENT_ROOT']; ?> !!! PENTING !!! Jika "$_SERVER['DOCUMENT_ROOT']" tidak bisa jalan di server anda dikarenakan

restrict dari penyedia jasa hosting, anda tetap boleh menggunakan "include 'head.php';" !!! KESALAHAN YANG FATAL !!! JANGAN GUNAKAN "VARIABEL" DALAM FUNGSI INCLUDE / REQUIRE Contoh: body.php ----- <?php include $_GET['file']; echo "<br>Ini adalah contant atau isi dari website ku<br>"; ?> ----- BAHAYA !!! kenapa?? karena orang lain bisa menambahkan file dari luar ...!!! binggo..!!! server anda kena...!!! ------

Membahas Fungsi if - ifelse - else 24-03-2007 | 00:16:54 | Halaman Ini dibaca 7004 kali Di bagian ini kita akan membahas - Define - PHP Decision Making Ok kita mulai - Define di sini saya akan jelaskan sedikit tentang define: define mirip dengan, "string": --------------- <?php define("HELLO", "Hello world!"); echo HELLO; ?> --------------- Nanti hasilnya: "Hello world." - PHP Decision Making PHP Decision Making yang akan saya jelas kan kali ini adalah yang sering di pakai dalam programing website - if

- else - elseif Penggunaan fungsi "if" Sebagai penalaran "if" anda samakan dengan "jika" Contoh: if (kondisi expresi) { kode anda; } Contoh Penerapan: <?php if ($user == b_scorpio) { echo "user anda b_scorpio"; } ?> Contoh Penerapan untuk user autentifikasi: <?php if ($user == b_scorpio && $password == 8_5c0rp10) { echo "anda berhasil login"; } ?> Penggunaan fungsi "else" Sebagai penalaran anda asumsikan "else" sebagai "jika tidak" Contoh: if (kondisi expresi) { kode anda; } else { kode anda; } Contoh Penerapan: <?php if ($user == b_scorpio) { echo "user anda b_scorpio"; } else

{ echo "anda bukan b_scorpio"; } ?> Contoh Penerapan untuk user autentifikasi: <?php if ($user == b_scorpio && $password == 8_5c0rp10) { echo "anda berhasil login"; } else { echo "anda tidak bisa login"; } ?> Penggunaan fungsi "elseif" "elseif" di gunakan untuk, statment "if" lebih dari satu Contoh Penerapan untuk user autentifikasi: -------------- <?php if ($user == b_scorpio) { echo "anda login sebagai $user"; } elseif ($user == alk) { echo "anda login sebagai $user"; } elseif ($user == johan) { echo "anda login sebagai $user"; } else { echo "anda tidak bisa login"; } ?>

Membatasi Donload Dengan PHP <?php
