# ReflectionProperty::isPublic

(PHP 5, PHP 7, PHP 8)

ReflectionProperty::isPublic — Checks if property is public

### 说明

public ReflectionProperty::isPublic(): bool

Checks whether the property is public.

### 参数

此函数没有参数。

### 返回值

`true` if the property is marked public, `false` otherwise.

> 注意: Note this refers only to the main visibility, and not to a set-visibility, if specified.

### 注释

> 注意: Be aware that a property being `public` does not always imply is it publicly writeable. A property could be virtual with no `set` hook, or it could be `readonly` and already have been written to, or it could have a `set` visibility defined that is non-public. In all of those cases, this method will return `true` but the property will not be writeable.
