{"source_text": "# PHP - PEAR: A Comprehensive Guide for Beginners\n\n## Introduction to PEAR\n\nHello, aspiring PHP developers! Today, we're going to dive into the world of PEAR, a fantastic tool that will make your PHP programming journey much smoother. As your friendly neighborhood computer teacher, I'm excited to guide you through this adventure. Let's start with the basics!\n\n### What is PEAR?\n\nPEAR stands for PHP Extension and Application Repository. Think of it as a treasure chest filled with ready-to-use PHP components. It's like having a magical toolbox that can help you build amazing web applications without reinventing the wheel every time.\n\n## Getting Started with PEAR\n\n### Installing PEAR\n\nBefore we can use PEAR, we need to install it. Don't worry; it's easier than you might think!\n\n1. For Windows users:\n - Download the go-pear.phar file from the official PEAR website.\n - Open your command prompt and navigate to the folder where you downloaded the file.\n - Run the following command:\n\n\nphp go-pear.phar\n\n\n2. For Mac and Linux users:\n - Open your terminal and run:\n\n\ncurl -O https://pear.php.net/go-pear.phar\nphp go-pear.phar\n\n\nFollow the installation prompts, and voila! You've got PEAR installed.\n\n## Using PEAR Packages\n\nNow that we have PEAR installed, let's explore how to use its packages. It's like opening that magical toolbox and picking out the perfect tool for the job!\n\n### Installing a PEAR Package\n\nLet's install a popular PEAR package called HTML_QuickForm which helps create and validate HTML forms.\n\n\npear install HTML_QuickForm\n\n\n### Creating a Simple Form with HTML_QuickForm\n\nNow, let's create a simple registration form using the package we just installed. Here's an example:\n\nphp\n<?php\nrequire_once 'HTML/QuickForm.php';\n\n$form = new HTML_QuickForm('registration', 'post');\n\n$form->addElement('text', 'username', 'Username:');\n$form->addElement('password', 'password', 'Password:');\n$form->addElement('submit', null, 'Register');\n\nif ($form->validate()) {\n echo '<h2>Thank you for registering!</h2>';\n echo 'Username: ' . $form->getElement('username')->getValue() . '<br>';\n echo 'Password: ' . str_repeat('*', strlen($form->getElement('password')->getValue()));\n} else {\n $form->display();\n}\n\n\nLet's break this down:\n\n1. We include the HTML_QuickForm package.\n2. We create a new form object.\n3. We add form elements: a text field for the username, a password field, and a submit button.\n4. We check if the form is submitted and valid.\n5. If valid, we display a thank you message with the entered username (and asterisks for the password).\n6. If not valid or not submitted, we display the form.\n\n## PEAR Package Management\n\nPEAR comes with a handy package manager. Let's look at some common commands:\n\n| Command | Description |\n|---------|-------------|\n| pear list | Lists installed packages |\n| pear search <keyword> | Searches for packages |\n| pear install <package> | Installs a package |\n| pear upgrade <package> | Upgrades a package |\n| pear uninstall <package> | Uninstalls a package |\n\n## Creating Your Own PEAR Package\n\nFeeling adventurous? Let's create a simple PEAR package! We'll make a basic calculator class.\n\n1. Create a file named Calculator.php:\n\nphp\n<?php\nclass Calculator\n{\n public function add($a, $b) {\n return $a + $b;\n }\n\n public function subtract($a, $b) {\n return $a - $b;\n }\n\n public function multiply($a, $b) {\n return $a * $b;\n }\n\n public function divide($a, $b) {\n if ($b == 0) {\n throw new Exception(\"Division by zero!\");\n }\n return $a / $b;\n }\n}\n\n\n2. Create a package.xml file:\n\nxml\n<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<package version=\"2.0\" xmlns=\"http://pear.php.net/dtd/package-2.0\">\n <name>Calculator</name>\n <channel>pear.php.net</channel>\n <summary>Simple calculator class</summary>\n <description>A basic calculator class with add, subtract, multiply, and divide functions.</description>\n <lead>\n <name>Your Name</name>\n <user>yourusername</user>\n <email>[email protected]</email>\n <active>yes</active>\n </lead>\n <date>2023-06-15</date>\n <version>\n <release>1.0.0</release>\n <api>1.0.0</api>\n </version>\n <stability>\n <release>stable</release>\n <api>stable</api>\n </stability>\n <license uri=\"http://www.php.net/license\">PHP License</license>\n <notes>Initial release</notes>\n <contents>\n <dir name=\"/\">\n <file name=\"Calculator.php\" role=\"php\" />\n </dir>\n </contents>\n <dependencies>\n <required>\n <php>\n <min>5.0.0</min>\n </php>\n <pearinstaller>\n <min>1.4.0</min>\n </pearinstaller>\n </required>\n </dependencies>\n <phprelease />\n</package>\n\n\n3. Package your class:\n\n\npear package\n\n\nCongratulations! You've just created your first PEAR package.\n\n## Conclusion\n\nWe've journeyed through the basics of PEAR, from installation to creating our own package. Remember, PEAR is like a Swiss Army knife for PHP developers - it's got a tool for almost every job. As you continue your PHP adventure, you'll find PEAR to be an invaluable companion.\n\nKeep exploring, keep coding, and most importantly, have fun! Who knows? Maybe the next big PEAR package will be created by you!", "target_language": "id"}

PHP - PEAR

PHP - PEAR: Panduan Lengkap untuk Pemula

Pengenalan ke PEAR

Halo, para pengembang PHP yang berambisi! Hari ini, kita akan mendalam ke dunia PEAR, alat yang fantastis yang akan membuat perjalanan pemrograman PHP Anda menjadi lebih mulus. Sebagai guru komputer tetangga yang ramah, saya sangat antusias untuk memandu Anda dalam petualangan ini. Mari kita mulai dari dasar-dasar!

Apa Itu PEAR?

PEAR adalah singkatan dari PHP Extension and Application Repository. Bayangkan itu seperti sebuah peti Harta Karun yang penuh dengan komponen PHP siap pakai. Itu seperti memiliki sebuah kotak pernak-pernik ajaib yang dapat membantu Anda membangun aplikasi web yang menakjubkan tanpa perlu menciptakan roda lagi.

Memulai dengan PEAR

Menginstal PEAR

Sebelum kita dapat menggunakan PEAR, kita perlu menginstalnya. Jangan khawatir; itu jauh lebih mudah daripada yang Anda pikirkan!

Untuk pengguna Windows:

Unduh file go-pear.phar dari situs web resmi PEAR.
Buka command prompt dan navigasikan ke folder tempat Anda mendownload file tersebut.
Jalankan perintah berikut:

php go-pear.phar
```

2. Untuk pengguna Mac dan Linux:
- Buka terminal dan jalankan:

curl -O https://pear.php.net/go-pear.phar php go-pear.phar


Ikuti petunjuk instalasi, dan voila! Anda sudah menginstal PEAR.

## Menggunakan Paket PEAR

Sekarang kita memiliki PEAR terinstal, mari kita jelajahi bagaimana menggunakan paketnya. Itu seperti membuka kotak pernak-pernik ajaib dan memilih alat yang sempurna untuk pekerjaan Anda!

### Menginstal Paket PEAR

Mari kita instal paket PEAR populer yang disebut `HTML_QuickForm` yang membantu membuat dan validasi formulir HTML.

pear install HTML_QuickForm


### Membuat Formulir Sederhana dengan HTML_QuickForm

Sekarang, mari kita buat formulir pendaftaran sederhana menggunakan paket yang kita baru saja instal. Ini adalah contoh:

```php
<?php
require_once 'HTML/QuickForm.php';

$form = new HTML_QuickForm('registration', 'post');

$form->addElement('text', 'username', 'Username:');
$form->addElement('password', 'password', 'Password:');
$form->addElement('submit', null, 'Register');

if ($form->validate()) {
echo '<h2>Terima kasih telah mendaftar!</h2>';
echo 'Username: ' . $form->getElement('username')->getValue() . '<br>';
echo 'Password: ' . str_repeat('*', strlen($form->getElement('password')->getValue()));
} else {
$form->display();
}
?>

mari kitauraikan ini:

Kita termasukkan paket HTML_QuickForm.
Kita membuat objek formulir baru.
Kita menambahkan elemen formulir: field teks untuk username, field password, dan tombol submit.
Kita memeriksa apakah formulir dikirimkan dan valid.
Jika valid, kita tampilkan pesan terima kasih dengan username yang dimasukkan (dan bintang untuk password).
Jika tidak valid atau belum dikirimkan, kita tampilkan formulir.

Manajemen Paket PEAR

PEAR datang dengan manajer paket yang praktis. Mari kita lihat beberapa perintah umum:

Perintah	Deskripsi
`pear list`	Daftar paket yang terinstal
`pear search <keyword>`	Cari paket
`pear install <package>`	Instal paket
`pear upgrade <package>`	Perbarui paket
`pear uninstall <package>`	Uninstal paket

Membuat Paket PEAR Sendiri

Rasakan keberanian Anda? Mari kita buat paket PEAR sederhana! Kita akan membuat kelas kalkulator dasar.

Buat file bernama Calculator.php:

<?php
class Calculator
{
public function add($a, $b) {
return $a + $b;
}

public function subtract($a, $b) {
return $a - $b;
}

public function multiply($a, $b) {
return $a * $b;
}

public function divide($a, $b) {
if ($b == 0) {
throw new Exception("Pembagian oleh nol!");
}
return $a / $b;
}
}
?>

Buat file package.xml:

<?xml version="1.0" encoding="UTF-8"?>
<package version="2.0" xmlns="http://pear.php.net/dtd/package-2.0">
<name>Calculator</name>
<channel>pear.php.net</channel>
<summary>Kelas kalkulator sederhana</summary>
<description>Kelas kalkulator dasar dengan fungsi tambah, kurang, kali, dan bagi.</description>

<min>5.0.0</min>
</php>
<pearinstaller>
<min>1.4.0</min>
</pearinstaller>
</required>
</dependencies>
<phprelease />
</package>

Paketkan kelas Anda:

pear package

Selamat! Anda baru saja membuat paket PEAR pertama Anda.

Kesimpulan

Kita telah menjelajahi dasar-dasar PEAR, dari instalasi hingga membuat paket kita sendiri. Ingat, PEAR seperti sebuah pisau Switzerland bagi pengembang PHP - itu memiliki alat untuk hampir semua pekerjaan. Ketika Anda terus menjelajahi petualangan PHP, Anda akan menemukan PEAR sebagai teman yang tak ternilai.

Terus jelajahi, terus kode, dan yang paling penting, bersenang-senang! Siapa tahu? Mungkin paket PEAR besar berikutnya akan diciptakan oleh Anda!
