deprecated_argument: 一個函式,當使用已棄用的函式引數時,會觸發一個棄用通知。

將一個函式引數標記為棄用的,並在它被使用時通知。

每當使用一個棄用的函式引數時,都要使用這個函式。在這個函式被呼叫之前,必須通過與預設值比較或評估引數是否為空來檢查引數是否被使用。

比如說

if ( ! empty( $deprecated ) ) {
_deprecated_argument( __FUNCTION__, ‘3.0.0’ )。
}

有一個將被呼叫的鉤子deprecated_argument_run,可以用來獲取回溯,直到哪個檔案和函式使用了這個被棄用的引數。

目前的行為是,如果WP_DEBUG為真,會觸發一個使用者錯誤。
