Rule `no_unset_on_property`¶

Properties should be set to null instead of using unset.

Warning¶

Using this rule is risky¶

Risky when relying on attributes to be removed using unset rather than be set to null. Changing variables to null instead of unsetting means these still show up when looping over class variables and reference properties remain unbroken. With PHP 7.4, this rule might introduce null assignments to properties whose type declaration does not allow it.

Examples¶

Example #1¶

--- Original
+++ New
 <?php
-unset($this->a);
+$this->a = null;
