README

This library helps with the content field of the Page Telegraph API object. It converts an HTML string or a DOMDocument into the format required by the Telegraph API, and also converts it back to an HTML string or a DOMDocument.

Installation

To install this library run the command:

composer require candysax/telegraph-node-converter

Usage

Converting from HTML to an array of Node

As the source data for conversion, the convertToNode method accepts a string containing html tags or a DOMDocument object. The result can be obtained as an array of Node or its representation as a JSON string.

$nodes = HTML::convertToNode('<p>Hello <b>world</b></p>');

Get as array:

$nodes->array();

Array
(
    [0] => Array
        (
            [tag] => p
            [children] => Array
                (
                    [0] => Hello
                    [1] => Array
                        (
                            [tag] => b
                            [children] => Array
                                (
                                    [0] => world
                                )

                        )

                )

        )

)

Get as JSON:

$nodes->json();

'[{"tag":"p","children":["Hello ",{"tag":"b","children":["world"]}]}]'

Passing the DOMDocument object as a data source for conversion:

$dom = new DOMDocument();
$dom->loadHTML('<p>Hello world <a href="https://example.com/">link</a></p>');

$nodes = HTML::convertToNode($dom)->json();

Converting from an array of Node to HTML

As the source data for the conversion, the convertToHtml method accepts an array of Node or a JSON string. The result can be obtained in the form of a string with HTML tags or a DOM object.

$html = Node::convertToHtml([
    [
        'tag' => 'p',
        'children' => [
            'Hello ',
            [
                'tag' => 'b',
                'children' => [
                    'world',
                ],

            ],
        ],
    ],
]);

Get as string:

$html->string();

'<p>Hello <b>world</b></p>'

Get as DOMDocument:

$html->dom();

DOMDocument Object

Multiple conversions

$input = '<p>Hello <b>world</b> <a href="https://example.com/">link</a></p>';

HTML::convertToNode($input)->convertToHtml()->convertToNode()->convertToHtml()->string();

Examples

Creating a Telegraph page:

use GuzzleHttp\Client;
use Candysax\TelegraphNodeConverter\HTML;

function createPage() {
    $client = new Client();
    $client->request('POST', 'https://api.telegra.ph/createPage', [
        'form_params' => [
            'access_token' => 'your_telegraph_token',
            'title' => 'Example',
            'content' => HTML::convertToNode(
                '<p>Hello world <a href="https://example.com/">link</a></p>'
            )->json(),
        ],
    ]);
}

Getting the content of the Telegraph page:

use GuzzleHttp\Client;
use Candysax\TelegraphNodeConverter\HTML;

function getPageContent() {
    $client = new Client();
    $response = $client->request('POST', 'https://api.telegra.ph/getPage', [
        'form_params' => [
            'path' => 'path_to_the_telegraph_page',
            'return_content' => true,
        ],
    ])->getBody();
    $data = json_decode($response, true);

    return Node::convertToHtml($data['result']['content'])->string();
}
