- 2. PURPOSE Dengan pesatnya perkembangan Internet dan World Wide Web ada peningkatan permintaan untuk pengembang dengan kemampuan untuk melakukan manipulasi Web data lebih maju. Siswa yang terlibat dalam pengembangan Web statis membutuhkan teknik untuk memanipulasi konten Web sehingga web menjadi dinamis. Tujuan dari program PHP adalah alat dan teknik untuk mengembangkan lebih dinamis Web berbasis aplikasi, dengan manipulasi data yang disimpan dalam database online

- 4. 1. INTRODUCTION PHP (Personal Home Page Tools) created by Rasmus Lerdorf In 1994, umumnya digunakan untuk: 1. Melakukan fungsi sistem: membuat, membuka, membaca dari, menulis, dan menutup file di sistem, menjalankan perintah sistem, membuat direktori, dan mengubah hak akses. 2. Mengumpulkan data dari bentuk: menyimpan data ke file, mengirim data melalui email, mengembalikan data dimanipulasi untuk pengguna. 3. Akses database dan menghasilkan konten on-the-fly, atau membuat antarmuka Web untuk menambahkan, menghapus, dan memodifikasi elemen-elemen dalam database Anda. 4. Mengatur cookie dan variabel akses. 5. Otentikasi pengguna PHP untuk membatasi akses ke bagian situs Web Anda. 6. Membuat gambar on-the-fly. 7. Enkripsi data.

- 10. 3. GETTING STARTED WITH VARIABLES 1. Variable Scalar, berisi satu nilai dalam satu waktu • Integers • floating poin numbers (floats/doubles). • Strings.Text and/or numeric yg ada diantara double quotes (" ") or single quotes (' ') 2. Variable Arrays, berisi sejumlah nilai dan array lain sehingga membentuk multidimensi array 3. HTML Variabel, variable yg didapat dari HTML form atau URL link 4. Supperglobal Variable, variable yg sudah ada di php engine
- 11. VARIABLE SCOPE 1. 2. Sigle Scope Global Scope dan Local Scope <?php var $r = 'I am r.'; class foo { var $bar = 'I am bar.'; var $arr = array('I am A.', 'I am B.', 'I am C.'); } $foo = new foo(); $bar = 'bar'; $baz = array('foo', 'bar', 'baz', 'quux'); echo $foo->$bar . "n"; echo $foo->$baz[1] . "n"; ?>
- 13. 4. OPERATORS Assignment Operator : =, += , -= , and .= Arithmetic Operator: Addition(+), subtraction(-), multiplication(*), division(/), modulus(%) Comparison Operator equal to (==), not equal to (!=), greater than (>), less than(<), greater than or equal to (>=), less than or equal to (<=) (&&) and; (||) or ; NOT (!).
- 14. 5. CONTROL STRUCTURE if continue else switch elseif/else if declare while return do-while require for include foreach require_once break include_once goto
- 15. ARRAYS IN PHP <?php $array = array( "foo" => "bar", "bar" => "foo", 100 => -100, -100 => 100, ); var_dump($array); ?> count(), is_array(), explode(), implode(), split(), preg_split(), unset() Isset() print_r() var_dump()
- 16. 7. FUNCTIONS function function_name($arg_1, $arg_2, ..., $arg_n) { code_line1; code_line2; code_line3; return ($value); //stops execution of the function and returns its argument as the value at the point where the function was called. }
