PhpStorm 2022.2 Help

Code Inspection: Constant expression

Reports conditions and expressions that are always true, false or null.

Example (MySQL):

CREATE TABLE t1 (a TEXT, b INT, c BOOLEAN); SELECT a FROM t1 WHERE 'Cat' = 'Cat'; SELECT a FROM t1 WHERE 'Cat' = null;

The 'Cat' = 'Cat' is always true and will be reported.

The 'Cat' = null is always null and will be reported.

Suppress an inspection in the editor

  1. Position 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.
