Description

Description:

When formatting code with Prettier in PHP 8.4, parentheses are incorrectly added to a static property when instantiating an object. This causes a syntax error and breaks the application.

Example:

Before Prettier:

$identifier = new Yii::$app->class([]);

After Prettier:

$identifier = new Yii::$app()->class([]);

Expected behavior:
Prettier should leave the code as-is without adding parentheses when using new on a static property.

Actual behavior:
Prettier adds () to the static property, resulting in invalid syntax.

Impact:
Code breaks when executed, causing runtime errors in applications using this pattern.

Research direction

Start by reproducing the PHP 8.4 example from the issue with Prettier, comparing the code before and after formatting. Done means the static property in the new Yii::$app->class([]) pattern remains without added parentheses and the resulting PHP stays valid.
