Library to covert class names to file paths and vice-versa
This library provides facilities to guess/transform class names to files paths and vice-versa.
It uses the composer autoload to guess the best candidates using PSR-0 and PSR-4.
// require the composer autoloader for the class you want to investigate $autoloader = require(__DIR__ . '/vendor/autoload.php'); // for file candidates $converter = ClassFileConverter::fromComposerAutoloader($autoloader); $candidates = $classToFile->classToFileCandidates(ClassName::fromString('Foobar\\Barfoo\\MyClass')); echo (string) $candidates->empty(); // return true if there are no candidates echo (string) $candidates->best(); // path to the "best" candidate // or for class candidates $candidates = $classToFile->fileToClassCandidates(FilePath::fromString('lib/Foobar/BarFoo/MyClass.php'));
Yes it does, but only if the class exists. One of the purposes of this class is to be able to determine a file path for a class which may not exist (for example to generate a class in a new file).
You may also want to do this and not pollute your autoloading environment (unfortunately this library currently does pollute the autoloader, but it can be avoided in the future.
Glad you asked! This is can be useful when you want to generate an empty class in an empty file.
In some exceptional cases you may have a project which has more than one
composer autoloader, this is supported through the
ChainClassToFile classes, or most simply through the facade:
$converter = ClassFileConverter::fromComposerAutoloaders([ $autoloader1, $autoloader2 ]);
