---

Installation

composer require cyvax/privatebin_php

---

Default Instance

By default, the library is configured to use:

https://paste.i2pd.xyz/

You can override it with setUrl() or via constructor options.

---

Usage

Modern camelCase API

use Cyvax\Clients\Privatebin;

$result = (new Privatebin())
    ->setUrl("https://privatebin.net/")
    ->setText("Because ignorance is bliss!")
    ->setExpire("1hour")
    ->encodeAndPost();

Factory method

PrivatebinPHP::init() supports named parameters for a more concise setup on PHP 8+:

use Cyvax\Clients\Privatebin;

$result = Privatebin::init(
    url: "https://privatebin.net/",
    text: "Because ignorance is bliss!",
    expire: "1hour",
)->encodeAndPost();

---

Original snake_case API

use Cyvax\Clients\PrivatebinSnakeCase;

$result = (new PrivatebinSnakeCase())
    ->set_url("https://privatebin.net/")
    ->set_text("Because ignorance is bliss!")
    ->set_expire("1hour")
    ->encode_and_post();

Note

PrivatebinSnakeCase is also available as the alias \Cyvax\PrivatebinPHP for compatibility with older versions of the library.

---

Constructor Options

Both clients accept an options array in their constructor:

use Cyvax\Clients\Privatebin;

$result = (new Privatebin([
    "url"  => "https://privatebin.net/",
    "text" => "Because ignorance is bliss!",
]))->encodeAndPost();

---

Attachments

use Cyvax\Clients\Privatebin;

$result = (new Privatebin())
    ->setAttachment("/path/to/image.png")
    ->encodeAndPost();

Note

setAttachment() throws PrivatebinException if the file cannot be read.

An optional second argument overrides the attachment filename:

->setAttachment("/path/to/image.png", "screenshot.png")

---

SSL Verification

SSL verification is enabled by default. Disable it only for local or self-signed instances:

use Cyvax\Clients\Privatebin;

$result = (new Privatebin())
    ->setUrl("https://local.privatebin/")
    ->setSslVerify(false)
    ->setText("Hello!")
    ->encodeAndPost();

The ssl_verify key is also accepted in the constructor options array and in PrivatebinPHP::init().

---

Pipe-style API

PrivatebinPHPPipe provides functional-style helper closures.

On PHP versions supporting the pipe operator:

use Cyvax\Clients\PrivatebinPipe;

$result = PrivatebinPipe::init("https://privatebin.net/")
    |> PrivatebinPipe::text("Hello!")
    |> PrivatebinPipe::expire("1hour")
    |> PrivatebinPipe::encodeAndPost();

Without pipe support, it is recommended to use PrivatebinPHP or PrivatebinSnakeCase directly.

If needed, closures can still be invoked manually:

use Cyvax\Clients\PrivatebinPipe;

$client = PrivatebinPipe::init("https://privatebin.net/");

$client = PrivatebinPipe::text("Hello!")($client);
$client = PrivatebinPipe::expire("1hour")($client);

$result = PrivatebinPipe::encodeAndPost()($client);

---

Fetching and Decrypting

use Cyvax\Clients\Privatebin;

$client = new Privatebin();

// Fetch and decrypt in one call
$data = $client->fetchAndDecrypt($pasteId, $b58);

echo $data['paste'];
// $data['attachment'] and $data['attachment_name'] are set if the paste had an attachment

---

Interfaces

Interface	Namespace	Used by
PrivatebinClientInterface	Cyvax\Contracts	PrivatebinPHP (camelCase)
PrivatebinSnakeCaseClientInterface	Cyvax\Contracts	PrivatebinSnakeCase

Type-hint against an interface when you want to swap implementations:

use Cyvax\Contracts\PrivatebinClientInterface;

function postPaste(PrivatebinClientInterface $client): array {
    return $client->setText("Hello!")->encodeAndPost();
}
