Number Helper

In your AppView:

$this->loadHelper('Shim.Number');

instead of the core one.

You now have the empty-value handling of CakePHP 5.3+ in your Number helper:

• format()
• currency()

Instead of ternary checks you can pass your database values directly; it will print out an empty string (or a defined default string) where needed.

echo $this->Number->format($entity->value);
// or
echo $this->Number->format($entity->value, ['default' => '-']);

and

echo $this->Number->currency($entity->value);
// or
echo $this->Number->currency($entity->value, ['default' => '-']);
