Why does phpstrom 2019.2.3 give an undefined variable error in php files and a warning in 2018.3.2?

Question

phpstorm

Good afternoon, phpstrom 2018.3.2 and phpstrom 2019.2.3 are available . The problem is that in the old version in the *.php file, with the setting insptecctions undefined variables = warning

, a variable that was not declared was underlined as an error, but in the new version it is underlined as a warning, how to force it to be underlined as an error without changing the insptecctions settings undefined variables.
