ReflectionProperty::isPublic

(PHP 5, PHP 7, PHP 8)

ReflectionProperty::isPublic — Checks if property is public

Description

public function ReflectionProperty::isPublic(): bool

Checks whether the property is public.

Parameters

This function has no parameters.

Return Values

true if the property is marked public, false otherwise.

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

Notes

Note:
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.
