Test, validate and match regular expressions
This regex is designed to capture components from PHP code lines, specifically targeting refactoring tasks in the Adianti Framework. It extracts three main groups: a quoted text label (including Portuguese characters like 'ã'), a PHP variable representing the widget (e.g., $field), and a quoted width parameter (e.g., '50%'). It is highly useful for developers migrating from older methods like `form->addQuickField` to the newer `form->addFields` syntax.
