Flow analysis use casees:

• Indexing:
  • Determine references to a type
• Completion:
  • Discover context for completion
• Refactoring:
  • Find method calls, properties, etc

Non use cases:

• Finding references to a type in source code: Types can be structural elements (e.g. class properties, class names). Flow analysis cannot help with this.

  Although: if the property is used then flow analysis may be able to infertype information for it. But that "information" may well be in a completely different source file.

<?php

$ir = $interpret->interpret($code);
$ir->findMethodCalls(Class::class, 'foobar');

$node = $ir->nodeAtOffset(1234);
$node->getRange()->start(); // new LineCol(1, 1);
if ($node instanceof TypedNode) {
    echo $node->getType(); // e.g. new StringLiteralType("foobar"), new StringType(), etc;
}
if ($node instanceof MethodCall) {
    echo $node->getClassType(); // new ClassType("Foobar")
    echo $node->getReturnType();
}
if ($node instanceof UnhandledNode) {
    echo $node->getNodeClass();
