Perpustakaan untuk mengonversi artikel HTML, postingan blog, atau konten serupa ke AMP (Accelerated Mobile Pages).
Catatan : Library ini tidak dimaksudkan untuk mengonversi seluruh dokumen HTML, jika Anda ingin mengonversi seluruh halaman sebaiknya gunakan pustaka yang lebih canggih, misalnya: Lullabot/amp-library
composer require magyarandras/amp-converter
Contoh sederhana:
Pastikan kode HTML Anda tidak mengandung tag atau atribut yang tidak valid di HTML5 jika tidak, AMP yang dihasilkan juga tidak valid.
<?php
use magyarandras AMPConverter Converter ;
/*
If you have images with unknown dimensions in your HTML code and use relative URLs, you must pass the images' base URL to the constructor.
Examples:
$converter = new Converter('https://example.com');
$converter = new Converter('https://cdn.example.com');
*/
$ converter = new Converter ();
//Load built-in converters
$ converter -> loadDefaultConverters ();
//HTML to convert
$ html = '
<p><strong>This is a sample HTML code generated by TinyMCE.</strong></p>
<p><strong><img src="https://cdn.example.com/photo/example_960_720.jpg" alt="" width="960" height="640" /></strong></p>

//Convert html to amp html
$ amphtml = $ converter -> convert ( $ html );
//Get the necessary amp components
$ amp_scripts = $ converter -> getScripts ();
print_r ( $ amphtml );
echo PHP_EOL ;
print_r ( $ amp_scripts );
Keluarannya:

[0] => <script async custom-element="amp-youtube" src="https://cdn.ampproject.org/v0/amp-youtube-0.1.js"></script>
[1] => <script async custom-element="amp-twitter" src="https://cdn.ampproject.org/v0/amp-twitter-0.1.js"></script>
)
Anda dapat menentukan konverter mana yang akan digunakan dengan memuatnya secara manual:
<?php
use magyarandras AMPConverter Converter ;
use magyarandras AMPConverter TagConverter AMPImgZoom ;
use magyarandras AMPConverter TagConverter AMPYoutube ;
//PHP 7+ syntax:
//use magyarandrasAMPConverterTagConverter{AMPImgZoom,AMPYoutube}
$ converter = new Converter ();
$ converter -> addConverter ( new AMPImgZoom ());
$ converter -> addConverter ( new AMPYoutube ());
$ amphtml = $ converter -> convert ( $ html );
$ amp_scripts = $ converter -> getScripts ();
print_r ( $ amphtml );
print_r ( $ amp_scripts );
Jika Anda memiliki gambar dengan dimensi yang tidak diketahui dalam kode HTML Anda (Anda harus menghindari situasi ini jika mungkin) dan menggunakan URL relatif, Anda harus meneruskan URL dasar gambar tersebut ke konstruktor. Anda juga dapat menentukan batas waktu untuk memperoleh ukuran satu gambar (defaultnya adalah 10 detik). (Catatan: batas waktu berlaku untuk setiap gambar, bukan untuk keseluruhan proses)
<?php
use magyarandras AMPConverter Converter ;
$ converter = new Converter ([
' image_base_url ' => ' https://example.com ' , //This base URL will be used if the src of an image is a relative path.
' image_timeout ' => 5 //Obtaining the size of a single image (downloading the required data) can't take longer than 5 seconds.
]);
//Load built-in converters
$ converter -> loadDefaultConverters ();
//HTML to convert
$ html = '
<p><strong>This is a sample HTML code generated by TinyMCE.</strong></p>
<p><strong><img src="images/picture.jpg" alt="Sample image" /></strong></p>
' ;
//Convert html to amp html
$ amphtml = $ converter -> convert ( $ html );
//Get the necessary amp components
$ amp_scripts = $ converter -> getScripts ();
print_r ( $ amphtml );
echo PHP_EOL ;
print_r ( $ amp_scripts );
Pustaka tidak dapat mendukung semuanya, tetapi Anda dapat memperluasnya dengan konverter Anda sendiri (atau Anda dapat mengganti yang sudah ada jika perlu).
Misalnya, pertimbangkan hal berikut: Anda menggunakan pustaka hitung mundur jQuery di beberapa artikel/postingan blog dan Anda ingin mengonversi kode berikut ke AMP.
<!-- The following line should be replaced with amp-date-countdown component -->
< div data-countdown =" 2038/01/19 " > </ div >
<!-- Countdown library: http://hilios.github.io/jQuery.countdown/examples/multiple-instances.html -->
< script >
$ ( '[data-countdown]' ) . each ( function ( ) {
var $this = $ ( this ) , finalDate = $ ( this ) . data ( 'countdown' ) ;
$this . countdown ( finalDate , function ( event ) {
$this . html ( event . strftime ( '%D days %H:%M:%S' ) ) ;
} ) ;
} ) ;
</ script >
Anda dapat membuat kelas konverter khusus yang mengimplementasikan TagConverterInterface.
<?php
class CountdownConverter implements magyarandras AMPConverter TagConverterInterface
{
private $ necessary_scripts = [];
private $ extension_scripts = [
' <script async custom-element="amp-date-countdown" src="https://cdn.ampproject.org/v0/amp-date-countdown-0.1.js"></script> ' ,
' <script async custom-template="amp-mustache" src="https://cdn.ampproject.org/v0/amp-mustache-0.2.js"></script> '
];
public function convert ( DOMDocument $ doc )
{
$ query = ' //div[@data-countdown] ' ;
$ xpath = new DOMXPath ( $ doc );
$ entries = $ xpath -> query ( $ query );
if ( $ entries -> length > 0 ) {
$ this -> necessary_scripts = $ this -> extension_scripts ;
}
foreach ( $ entries as $ tag ) {
//Although in this example there isn't any validation, you definitely should check if the date is valid.
$ timestamp = strtotime ( $ tag -> getAttribute ( ' data-countdown ' ));
$ countdown = $ doc -> createElement ( ' amp-date-countdown ' );
$ countdown -> setAttribute ( ' timestamp-seconds ' , $ timestamp );
$ countdown -> setAttribute ( ' layout ' , ' fixed-height ' );
$ countdown -> setAttribute ( ' height ' , ' 50 ' );
$ template = $ doc -> createElement ( ' template ' );
$ template -> setAttribute ( ' type ' , ' amp-mustache ' );
$ paragraph = $ doc -> createElement ( ' p ' );
$ paragraph -> setAttribute ( ' class ' , ' p1 ' );
$ text = $ doc -> createTextNode ( ' {{d}} days, {{h}} hours, {{m}} minutes and {{s}} seconds ' );
$ paragraph -> appendChild ( $ text );
$ template -> appendChild ( $ paragraph );
$ countdown -> appendChild ( $ template );
$ tag -> parentNode -> replaceChild ( $ countdown , $ tag );
}
return $ doc ;
}
public function getNecessaryScripts ()
{
return $ this -> necessary_scripts ;
}
}
Menggunakan konverter khusus:
<?php
require_once ' vendor/autoload.php ' ;
require_once ' CountdownConverter.php ' ;
use magyarandras AMPConverter Converter ;
$ converter = new Converter ();
//Load built-in converters
$ converter -> loadDefaultConverters ();
$ converter -> addConverter ( new CountdownConverter ());
$ html = ' <div><h1>Hello!</h1><div data-countdown="2038/01/19"></div></div> ' ;
//Convert html to amp html
$ amphtml = $ converter -> convert ( $ html );
//Get the necessary amp components
$ amp_scripts = $ converter -> getScripts ();
print_r ( $ amphtml );
print_r ( $ amp_scripts );
