SELECT CURDATE(), (
  (SUM(shares_copylink) + ... +SUM(shares_whatsapp))
   - (select * from shares order by date desc limit 1)) FROM communities AS DailyShares

tengo el siguiente escenario:

un array:

```php
        $array  = [
            [
                'char'  => ' ',
                'count' => 15,
            ],
            [
                'char'  => 'nombre',
                'count' => 25,
            ],
            [
                'char'  => '//Comentario',
                'count' => 30,
            ],
        ];
```

pensaba recorrerlo de la siguiente forma:

```php
        $buffer = '';
        foreach ($array as $line_constructor) {
            $buffer .= str_pad($line_constructor['char'], $line_constructor['count'], " ");
