README
phtml is pure object-oriented HTML construction templating library for PHP with functional interface, inspired by JavaTags and ScalaTags.
This fragment:
use Maxonfjvipon\Phtml\at; use function Maxonfjvipon\Phtml\{html5, attr, head, meta, title, link, text}; html5(attr([at::lang => 'en']), head( meta(attr([at::http_equiv => 'Content-Type', at::content => 'text/html', at::charset => 'UTF-8'])), title(text("Title")), link(attr(["href" => "/css/custom.css", "rel" => "stylesheet"])) ) )->asString();
will be turned into this html:
<!DOCTYPE html> <html lang='en'> <head> <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'/> <title>Title</title> <link href='/css/custom.css' rel='stylesheet'/> </head> </html>
Getting started:
Requirements
- PHP >= 8.0
Installation
composer require maxonfjvipon/phtml
Examples
basic:
Library provides all html tags as functions with only one exception - <var></var>. PHP does not allow you to create function named var since this word is reserved. So to create <var></var> tag use _var function
(if you know more elegant way to handle this <var></var> - please create an issue)
This code
use function Maxonfjvipon\Phtml\{html5, head, body, div, _var, text}; html5( head(), body( div( _var(text("Hello world!")) ) ) )->asString();
will render to you this html:
<!DOCTYPE html> <html> <head> </head> <body> <div> <var>Hello world!</var> </div> </body> </html>
Attributes:
To add attributes to your tag you should use attr function. Function accepts an array with arguments.
Array may has 'key' => 'value' and just 'value' elements:
use function Maxonfjvipon\Phtml\{a, attr}; a(attr(['href' => '/some/url', "download"]))->asString(); // <a href='/some/url' download></a>
Attributes will be rendered only if they are at the first place. Other attributes on other places will be ignored.
use function Maxonfjvipon\Phtml\{a, attr}; div(attr(['class' => 'div']), div())->asString(); // <div class='div'><div></div></div> div(div(), attr(['class' => 'div']))->asString(); // <div><div></div></div>
Library provides helper class Maxonfjvipon\Phtml\at that contains all existed html attributes as consts.
You can use it in this way:
use Maxonfjvipon\Phtml\at; use function Maxonfjvipon\Phtml\{html5, attr}; html5(attr([at::lang => "en"]))->asString(); // <!DOCTYPE html><html lang='en'></html>
Note!
at::class will return you \Maxonfjvipon\Phtml\at instead of expected 'class' (since ::class is reserved by PHP)
(if it's possible to override this ::class and you know how to do it - please create an issue)
To get 'class' string from at you can do at::_class or at::$class. Or you can just write it manually
use Maxonfjvipon\Phtml\at; use function Maxonfjvipon\Phtml\{html5, attr}; attr([at::class => 'main'])->asString(); // \Maxonfjvipon\Phtml\at='main' attr(['class' => 'main'])->asString(); // class='main' attr([at::$class => 'main'])->asString(); // class='main' attr([at::_class => 'main'])->asString(); // class='main'
Helpers:
Custom tags
You can create your custom tags using 2 helper functions: paired and unpaired:
use function Maxonfjvipon\Phtml\{unpaired, paired}; unpaired('somebody', attr(['class' => 'custom unpaired']))->asString(); // <somebody class='custom unpaired'/> paired('somebody', attr(['class' => 'custom paired']))->asString(); // <somebody class='custom paired'></somebody>
If you want to add many tags (for example from array) you can use tags function:
use function Maxonfjvipon\Phtml\{tags, div, unpaired, link}; tags(div(), unpaired('my'), link())->asString(); // <div></div><my/><link/>
Strings, Tags and Texts
Library is based on Maxonfjvipon\ElegantElephant\Txt class from ElegantElephant.
So besides attributes every paired tag can accept other tags, strings and Texts.
This tag:
use Maxonfjvipon\ElegantElephant\TxtOf; use function Maxonfjvipon\Phtml\{div, link}; div(attr(['class' => 'main']), link(), // other tag TxtOf::str('text'), // Text text("alias"), // wrap string to Maxonfjvipon\ElegantElephant\Txt "just string", )->asString();
will be turned into:
<div class='main'> <link/>\n text\n alias\n just string\n </div>
Import
If you want to use all available tags and functions you have to add this import.
(if you know how to make this whole import shorter - please create an issue)
Keep in mind that some tag functions have the same name as built in php functions (like \header(), \time(), etc).
So make sure that you have imported these functions before using them.
use function Maxonfjvipon\Phtml\{ text, unpaired, paired, a, abbr, address, article, aside, audio, b, bdi, ddo, blockquote, body, button, canvas, caption, cite, code, colgroup, data, datalist, dd, del, dfn, div, dl, dt, em, fieldset, figcaption, figure, footer, form, h1, h2, h3, h4, h5, h6, head, header, i, iframe, ins, kbd, label, legend, li, main, map, mark, meter, nav, noscript, object, ol, optgroup, option, output, p, pre, progress, q, rb, rp, rt, rtc, ruby, s, samp, script, section, select, small, span, strong, style, sub, sup, table, tbody, td, template, textarea, tfoot, th, thead, time, title, tr, u, ul, video, attr, tags, br, html5, area, base, col, command, embed, hr, img, input, link, meta, param, source, track, wbr, _var, xmp };
