Laravel 5 - Compile String and Interpolate Using Blade API on Server

Question

Using the Blade service container I want to take a string with markers in it and compile it down so it can be added to the blade template, and further interpolated.

This should do it:

// CustomBladeCompiler.php

use Symfony\Component\Debug\Exception\FatalThrowableError;

class CustomBladeCompiler
{   
    public static function render($string, $data)
    {
        $php = Blade::compileString($string);

        $obLevel = ob_get_level();
        ob_start();
        extract($data, EXTR_SKIP);

        try {
            eval('?' . '>' . $php);
        } catch (Exception $e) {
            while (ob_get_level() > $obLevel) ob_end_clean();
            throw $e;
        } catch (Throwable $e) {
            while (ob_get_level() > $obLevel) ob_end_clean();
            throw new FatalThrowableError($e);
        }

        return ob_get_clean();
    }
}

Usage:

$first_name = 'Joe';
$dbString = '<p>Welcome {{ $first_name }},</p>';

return CustomBladeCompiler::render($dbString, ['first_name' => $first_name]);
