Sejarah Bahasa Pemrograman PHP

                 Sejarah Bahasa Pemrograman PHP

Banyak Programmer PHP tidak mengetahui sejarah dari PHP, berikut adalah sedikit sejarah pendek dari bahasa pemrograman yang sangat populer di seluruh dunia.  

PHP diciptakan oleh Rasmus Lerdorf, seorang pemrograman C yang andal. semula PHP hanya digunakan untuk mencatat jumlah pengunjung pada homepagenya. Pada waktu itu PHP masih bernama Form Interpreted (FI), yang wujudnya berupa sekumpulan skrip yang digunakan untuk mengolah data formulir dari web.
Selanjutnya Rasmus merilis kode sumber tersebut untuk umum dan menamakannya PHP/FI. Dengan perilisan kode sumber ini menjadi sumber terbuka, maka banyak pemrogram yang tertarik untuk ikut mengembangkan PHP.

Pada November 1997, dirilis PHP/FI 2.0. Pada rilis ini, interpreter PHP sudah diimplementasikan dalam program C. Dalam rilis ini disertakan juga modul-modul ekstensi yang meningkatkan kemampuan PHP/FI secara signifikan. Pada tahun 1997, sebuah perusahaan bernama Zend yang terdiri  dari sebuah kelompok pengembangan software yang terdiri dari Rasmus, Zeew Suraski, Andi Gutman, Stig Bakken, Shane Caraveo dan Jim Winstead bekerja selama tujuh bulan ulang interpreter PHP menjadi lebih bersih, lebih baik, dan lebih cepat. Kemudian pada Juni 1998, perusahaan tersebut merilis interpreter baru untuk PHP dan meresmikan rilis tersebut sebagai PHP 3.0 dan singkatan PHP diubah menjadi akronim berulang PHP: Hypertext Preprocessing.

Pada pertengahan tahun 1999, Zend merilis interpreter PHP baru dan rilis tersebut dikenal dengan PHP 4.0. PHP 4.0 adalah versi PHP yang paling banyak dipakai pada awal abad ke-21. Versi ini banyak dipakai disebabkan kemampuannya untuk membangun aplikasi web kompleks tetapi tetap memiliki kecepatan dan stabilitas yang tinggi.
Pada Juni 2004, Zend merilis PHP 5.0. Dalam versi ini, inti dari interpreter PHP mengalami perubahan besar. Versi ini juga memasukkan model pemrograman berorientasi objek ke dalam PHP untuk menjawab perkembangan bahasa pemrograman ke arah paradigma berorientasi objek.

Kelebihan PHP dari bahasa Pemrograman lain

1. 'Bahasa pemrograman PHP adalah sebuah bahasa script yang tidak melakukan sebuah kompilasi dalam penggunaanya.'
2. 'Web Server yang mendukung PHP dapat ditemukan dimana - mana dari mulai apache, IIS, Lighttpd, hingga Xitami dengan konfigurasi yang relatif mudah.'
3. 'Dalam sisi pengembangan lebih mudah, karena banyaknya milis - milis dan developer yang siap membantu dalam pengembangan.'
4. 'Dalam sisi pemahamanan, PHP adalah bahasa scripting yang paling mudah karena memiliki referensi yang banyak.'
5. 'PHP adalah bahasa open source yang dapat digunakan di berbagai mesin (Linux, Unix, Macintosh, Windows) dan dapat dijalankan secara runtime melalui console serta juga dapat menjalankan perintah-perintah system.'

How To Create Array to XML with PHP

How to Create Array to XML with PHP

Extensible Markup Language (XML) is a markup language which defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined in the XML 1.0 Specification produced by the W3C, and several other related specifications, all  open standards.

<?php
$data = array(
  'name' => array(
    'first' => 'Randy',
    'last' => 'Septian'
  ),
  'phone' => array(
    'personal' => array(
      'mobile' => '085687xxxxx',
      'home' => '0217788xxxx'
    ),
    'office' => array(
      'fax' => '0217788xxxx'
    )
  ),
  'gender' => 'male'
);

$xml = new XmlWriter();
$xml->openMemory();
$xml->startDocument('1.0', 'UTF-8');
$xml->startElement('root');

function write(XMLWriter $xml, $data){
    foreach($data as $key => $value){
        if(is_array($value)){
            $xml->startElement($key);
            write($xml, $value);
            $xml->endElement();
            continue;
        }
        $xml->writeElement($key, $value);
    }
}

PHP Error Logging Reporting Handler

PHP Error, Logging, Reporting and Handler 


1. error_get_last()
example:

echo $testing;print_r(error_get_last());?>

Output :

Array([type] => 8[message] => Undefined variable: testing[file] => C:\webfolder\test.php[line] => 2)

2. error_log(error,type,destination,headers)

Parameter	Description
error	Required. The error message to log
type	Optional. Specifies the error log type. Possible log types: 0 - Default. The error is sent to the servers logging system or a file, depending on how the error_log configuration is set in the php.ini file 1 - The error is sent by email to the address in the destination parameter. This message type is the only one that uses the headers parameter 2 - The error is sent through the PHP debugging connection. This option is only available in PHP 3 3 - The error is added to the file destination string
destination	Optional. Specifies where to send the error message. The value of this parameter depends on the value of the "type" parameter
headers	Optional. Only used if the "type" parameter is "1". Specifies additional headers, like From, Cc, and Bcc. The additional headers should be separated with a CRLF (\r\n).Note: When sending an email, it must contain a From header. This can be set with this parameter or in the php.ini file.

example:

$test=2;
if ($test>1){error_log("A custom error has been triggered",1,"someone@example.com","From: webmaster@example.com");}?>

Output:

A custom error has been triggered

3. error_reporting(report_level)

Value	Constant	Description
1	E_ERROR	Fatal run-time errors. Errors that can not be recovered from. Execution of the script is halted
2	E_WARNING	Non-fatal run-time errors. Execution of the script is not halted
4	E_PARSE	Compile-time parse errors. Parse errors should only be generated by the parser
8	E_NOTICE	Run-time notices. The script found something that might be an error, but could also happen when running a script normally
16	E_CORE_ERROR	Fatal errors at PHP startup. This is like an E_ERROR in the PHP core
32	E_CORE_WARNING	Non-fatal errors at PHP startup. This is like an E_WARNING in the PHP core
64	E_COMPILE_ERROR	Fatal compile-time errors. This is like an E_ERROR generated by the Zend Scripting Engine
128	E_COMPILE_WARNING	Non-fatal compile-time errors. This is like an E_WARNING generated by the Zend Scripting Engine
256	E_USER_ERROR	Fatal user-generated error. This is like an E_ERROR set by the programmer using the PHP function trigger_error()
512	E_USER_WARNING	Non-fatal user-generated warning. This is like an E_WARNING set by the programmer using the PHP function trigger_error()
1024	E_USER_NOTICE	User-generated notice. This is like an E_NOTICE set by the programmer using the PHP function trigger_error()
2048	E_STRICT	Run-time notices. PHP suggest changes to your code to help interoperability and compatibility of the code
4096	E_RECOVERABLE_ERROR	Catchable fatal error. This is like an E_ERROR but can be caught by a user defined handle (see also set_error_handler())
8191	E_ALL	All errors and warnings, except level E_STRICT (E_STRICT will be part of E_ALL as of PHP 6.0)

example:

//Disable error reportingerror_reporting(0);
//Report runtime errorserror_reporting(E_ERROR | E_WARNING | E_PARSE);
//Report all errorserror_reporting(E_ALL);?>

4. restore_error_handler()

example:

//custom error handler functionfunction customError($errno, $errstr, $errfile, $errline)  {  echo "Custom error: [$errno] $errstr
";  echo " Error on line $errline in $errfile
";  }
//set user-defined error handlerset_error_handler("customError");
$test=2;
//trigger errorif ($test>1)  {  trigger_error("A custom error has been triggered");  }
//restore built-in error handlerrestore_error_handler();
//trigger error againif ($test>1)  {  trigger_error("A custom error has been triggered");  }?>

Output

Custom error: [1024] A custom error has been triggeredError on line 14 in C:\webfolder\test.php
Notice: A custom error has been triggered in C:\webfolder\test.php on line 21

Case Studies on PHP Website Security from XSS Attack and Sql Injection

XSS (Cross Side Scripting) is a way to enter tag/script HTML  (injection) in to website for disrupt thats website.
Example attack with XSS: entered HTML or Javascript Code in some form, such like Comment Form. entered comment like this

I want to enter comment with  <script>alert('this xss attack'); </scipt>

if thats website don't have XSS filtering, when the comment appear, the alert script will working.
In PHP there are so many function, where we can use for xss attack filtering, and we can combine to make own xss filtering function

function xss_filtering($text) {
     $f = stripslashes (strip_tags (htmlspecialchars ($text, ENT_QUOTES)));
    return $f;
}
$text_comment = xss_filtering($_POST['comment']);

SQL Injection is a technic for manipulation sql command ..
Example Sql Injection in login form with " 'OR 1=1;//     " , thats logic will like this

SELECT * FROM user_table WHERE username=' ' OR 1=1;// ' AND password ='anything';

the logic is true, and whos ever can enter, ok lets make anti sql injection with PHP.

function sql_injection_filtering($data){
    $filter = mysql_real_escape_string($data);
     return $filter;
}
$username = sql_injection_filtering($_POST['username']);
$password = sql_injection_filtering($_POST['password']);
if (!ctype_alnum($username) OR !ctype_alnum($password)){
    echo "Only alpha numeric";
} else {
    echo "Login Succes";
}

Manual PCNTL

Running a Case Sensitive Query Select String in MySql

contoh / example :
I have data in table user structure like this :

_ _ _ _ _ _ _ _ _
| ID  |  Name |
-------------------
| 1    |  Andre |
-------------------
| 2    |  andre  |
----------------------

when i using Select `ID`,`Name` from user where name = 'andre';
result is 2 row in set but i just need name 'andre' not 'Andre' , so you need case sensitive string

solution :

Select `ID`,`Name` from user where binary name = 'andre';
result is 1 row in set

Menggunakan Smarty Template Engine PHP

Mengapa menggunakan Smarty?

-Memisahkan logika presentasi dari logika bisnis (Kode dan desain dipisahkan)
-Jika kita menggunakan PHP inti dengan dicampur dengan HTML kemudian berantakan untuk mengelola.
-Tidak ada pengetahuan PHP diperlukan untuk mengelola template Smarty.
-Web desainer dan pengembang PHP dapat dengan mudah bekerja dan tidak saling menyalahkan. (Ketika mereka mengembangkan website besar)

Smarty menawarkan alat
- Data granular caching
- Template warisan
- Fungsional sandboxing untuk beberapa nama

Dimana menemukan?

Download paket dari smarty.net / men-download versi yang kompatibel dengan PHP Anda.

Bagaimana menginstal?
Unzip file yang didownload ke appserv smarty Anda / folder www dan menjalankan aplikasi.

Dasar sintaks di smarty yang
Pada file index.php (Di root folder aplikasi Anda)

a) Sertakan kelas smarty (Yang libs folder).
membutuhkan ('libs / Smarty.class.php');
b) Membuat obyek untuk kelas smarty yang
$ Smarty = new Smarty;
c) Menetapkan variabel
$ Smarty-> assign ("var_name", "Smarty");

Di sini:
"Var_name" adalah untuk digunakan dalam template Smarty (. Tpl file)
"Smarty" adalah nilai yang
