 static method used. You can also resolve types from a string (as shown in the
 ``bool`` parameter of the previous example)

+The TypeInfo component provides a new Type "ArrayShapeType" to define exact array structures with specific key-value type relationships.
+
+.. versionadded:: 7.3
+
+    The ``ArrayShapeType`` method was introduced in Symfony 7.3.
+
+Array shape types support:
+
+* Required and optional keys
+* Nested array shapes
+* Union types for values
+* Exact key ordering validation
+
+The ArrayShapeType support Associative Array definition::
+
+    use Symfony\Component\TypeInfo\Type;
+
+    // Simple array shape
+    $type = Type::arrayShape([
+        'name' => Type::string(),
+        'age' => Type::int()
+    ]);
+
+    // With optional keys (denoted by "?" suffix)
+    $type = Type::arrayShape([
+        'required_id' => Type::int(),
+        'optional_name?' => Type::string()
+    ]);
+
+But also, ``StringTypeResolver`` now supports parsing array shape notation::
+
+    use Symfony\Component\TypeInfo\TypeResolver\TypeResolver;
+
+    $resolver = new TypeResolver();
+
+    // Parse array shape definition
+    $type = $resolver->resolve('array{name: string, age: int}');
+
+    // Equivalent to:
+    Type::arrayShape([
+        'name' => Type::string(),
+        'age' => Type::int()
+    ]);
+
+    $type->is(typeof(['name' => 'Alice', 'age' => 30, ])); // true
+    $type->is(typeof(['name' => 'Alice', 'age' => '30', ])); // false (wrong age type)
