Fast and powerful php template engine

Syntax close to php for easy learning and management.

Installation

You can install the package via composer:

composer require tleckie/template

Printing variable:

{{$name}}

Flexibility of spaces in variables:

<p>{{$name}}</p>

<p>{{   $user->getName()   }}</p>

<p>
    {{
    $user->getName()
    }}
</p>

Printing constant:

{{CONSTANT}}

Set variables:

{set $variable = 'test'}

{set $variable = 355}

{set $userId = 25}

{set $userModel = new \MyNamespace\User($userId)}

{set $userModel = new \MyNamespace\User(25, 'John')}

Dump:

{dump $users}

Comments:

{# {dump $users} #}

Extends template:

<html>
<head></head>
<body>

    {extends Common/Header.html}
    
    <p>List</p>
        
    {foreach $users as $user}
        <p>{{$user->getName()}}</p>
    {endforeach}

    {extends Common/Footer.html}

</body>
</html>

If you add changes to the included templates as extensions, the compiler will not show these changes. To remove the compiled files you have the "flushCompiled()" method

$tpl = new Template(__DIR__.'/tpl/', '/var/www/cache/compiled/');
$tpl->flushCompiled();

You can enable development mode so that templates are always compiled.

use Tleckie\Template\Template;

$tpl = new Template(
    __DIR__.'/tpl/', 
    '/var/www/cache/compiled/', 
    null, 
    true // development mode
);

Conditionals if, else & elseif:

{if $title === 'title'}
    <div>{{$title}}</div>
{else}
    It is not a headline!
{endif}

{if $type === 'Orange'}
    <div>{{$type}}</div>
{elseif $title !== 'Apple'}
    It is not an Apple!
{else}
    Other fruit!
{endif}

{if $age >= 18}
    <div>Yes!</div>
{else}
    Ups :)
{endif}

{if $age !== 18}
    <div>Yes!</div>
{else}
    Ups :)
{endif}

Nested loops:

Foreach and for supported.

<html>
<head></head>
<body>

    {foreach $data as $key => $persons}
        {foreach $persons as $id => $name}
            <div><string>{{$name}}:</string>{{ $key }}</div>
        {endforeach}
    {endforeach}
    
</body>
</html>

Helpers:

Create your own helpers to invoke on the template.

{{$this->arrayHelper::last($persons)}}

Create the template instance:

<?php

require_once "vendor/autoload.php";

use Tleckie\Template\Template;

$tpl = new Template(__DIR__ . '/tpl/', '/var/www/cache/compiled/');

$data = [
    'names' => ['Marcos', 'John', 'Pedro', 'Marta'],
    'title' => 'User list',
    'users' => [
        new User('Marcos'), new User('John'), new User('Pedro')
    ]
];

$tpl->render('List/Users.html', $data);

Template List/Users.html

<html>
<head></head>
<body>
    {foreach $users as $user}
        <p>{{ strtoupper($user->getName()) }}</p>
    {endforeach}
</body>
</html>

Rules:

The Tleckie\Template\Compiler\Parser\Rules class establishes the rules for handling templates. You can create new rules to enrich your templating engine through the RuleInterface interface.

use Tleckie\Template\Template;
use Tleckie\Template\Compiler\Compiler;
use Tleckie\Template\Compiler\Parser\Rules;

$rules = [
    new Rules(),
    new MyOwnRules()
];

$compiler = new Compiler($rules);

$tpl = new Template(
    __DIR__.'/tpl/', 
    '/var/www/cache/compiled/',
     $compiler
);

Helpers:

You can create your own helpers to be invoked from templates to do complex tasks, manipulate objects or strings.

The Template class has a method for adding helpers. Note that by this mechanism you can also add your dependency injector.

<?php

require_once "vendor/autoload.php";

use Tleckie\Template\Template;

$tpl = new Template(
    __DIR__ . '/tpl/', 
    '/var/www/cache/compiled/'
);

$tpl->registerHelper(
    'arrayHelper', 
    new \MyNamespace\Infrastructure\Helpers\ArrayHelper()
);

Each helper added to the template object must have an alias to be invoked through it.

{{$this->arrayHelper::last($persons)}}

Helper example:

<?php

namespace MyNamespace\Infrastructure\Helpers;

use function end;

/**
 * Class ArrayHelper
 * @package MyNamespace\Infrastructure\Helpers
 * @author Teodoro Leckie Westberg <[email protected]>
 */
class ArrayHelper
{
    public static function last(array $array)
    {
        return end($array);
    }
}

That's all! I hope this helps you ;)
