Wrong quotation marks trigger PHP error

Hi,

in my debug.log, I get this error:

PHP Notice: Use of undefined constant ‘cli’ - assumed '‘cli’' in /wp-content/plugins/php-compatibility-checker/src/wpephpcompat.php on line 468

Within that file:

return defined( 'WP_CLI' ) || defined( 'PHPUNIT_TEST' ) || php_sapi_name() == ‘cli’;

The quotation marks around “cli” are actually for texts, not for PHP, hence, this error is triggered and really spamming my logs.
