The <strong>PHP Visualizer<\/strong> transforms PHP classes, interfaces, traits, and enums into clear, interactive UML class diagrams. By parsing PHP type declarations, access modifiers (<code>public<\/code>, <code>protected<\/code>, <code>private<\/code>), property declarations, and class relationships (<code>extends<\/code>, <code>implements<\/code>), web developers and backend architects can visually inspect application structure at a glance.<\/p>\n<h2>The Mechanics of PHP Visualizations<\/h2>\n<p>In VPasCode, PHP rendering automatically parses <code>class<\/code> statements, <code>interface<\/code> definitions, <code>enum<\/code> types, explicit property declarations, and type hints into structured visual diagram cards. Classes render as primary entity blocks, visibility flags reflect member access levels, and inheritance keywords generate clear structural relationship lines between visual nodes.<\/p>\n<h3>1.
