Code Inspection: Typed property might be uninitialized

Reports the attempts to read from an uninitialized typed property. Such attempts will result in TypeError.

Typed properties should be initialized in any of the following ways:

  • by a default value

  • in the constructor

  • by the __get() magic getter

  • in-place, at the moment of usage

See Uninitialized and Unset Properties ( for details.

In the following example, the $prop property is accessed before being initialized, which will result in a PHP Fatal error:

class ExampleClass { public int $prop; } $a = new ExampleClass(); echo $a->prop;

Suppress an inspection in the editor

  1. Place the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
