I have this example which works great:
$text = 'Lorem Ipsum';
$html = <<<HTML
<div>
<span>$text</span>
</div>
HTML;
Now how to do this the right way to get option 2 selected:
$val = 2;
$html = <<<HTML
<select>
<option if ($val == 1) {echo 'selected';} >Option 1</option>
<option if ($val == 2) {echo 'selected';} >Option 2</option>
<option if ($val == 3) {echo 'selected';} >Option 3</option>
</select>
HTML;
分享 I think this is the work for template engine - but don`t worry, is pretty easy to use.
Only thing you need is prepared project with composer and after that easily install one of the template engine (for this example I picked up Latté).
Install of composer:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
after that installing Latté:
php composer.phar require latte/latte
And on the end, you can create something like this:
$latte = new \Latte\Engine;
$latte->setTempDirectory('/path/to/tempdir');
$parameters['val'] = 2;
$html = $latte->renderToString('template.latte', $parameters);
and put this content into file "template.latte" in same directory:
<select>
{foreach [1, 2, 3] as $key}
<option {if $val === $key}>Option {$key}</option>
{/foreach}
</select>
This solution is used by professionals for many reasons:
BTW you always should use triple equals in condition in PHP (compares also type of variable). Its much more safe and you can save a lot of time of debug using this principle :-).
