A method call on a model, a comment, a line in a test fixture, an unrelated class that happens to have a method with the same name. That is what regex refactoring looks like. Regex does not know a method call from a string literal.</p> <p>Rector does. A young tool I found this month: it parses PHP into an AST with nikic/php-parser, applies transformation rules, prints the code back. Rename a class across the whole project. Change a method call, add an argument everywhere. The AST sees that this <code>fetch</code> is called on that type and touches only those places. Mechanical change becomes exact.</p>
