在魔術方法__callStatic中對Trait函數進行別名定義
<p>我有一個Queryable trait,它使用__callStatic方法建立一個Builder的新實例,並在其上執行呼叫的函數(如果存在)。它傳回Builder以便鍊式查詢(類似於Eloquent)。 <br /><br />現在我正在嘗試實現一個需要find()函數的接口,但是在Queryable trait的phpDoc中聲明了find()函數(@method static static find(mixed $primaryKeyValue) ),這就創造了衝突:</p><p><code></code></p>
<blockquote>
<p>Queryable的find(primaryKeyValue: mixed)的宣告必須與StorageInterface->find(primaryKeyValue: mixed)相容,無法建立介面方法。 </p>
</blockquote>
<p>為了解決這個衝突,我試著用類似trait別名的方式(use Queryable { Queryable::find as queryFind; })來解決,但是接著我遇到了...</p>
<blockquote>
<p>編譯錯誤:為appFrameworkTraitsQueryable::find定義了一個別名,但方法不存在。</p>
</blockquote>
<p>我似乎找不到解決方法,有位高手幫我嗎? :)(我相信這與類別上的某種存在檢查有關,因為它是魔術方法,但我也不知道如何修復它..)</p>
