			0 ignored issues – show Bug introduced 2017-06-11 20:05 UTC by Report Bug Copy Issue Report Consider using a different name than the imported variable `$message`, or did you forget to import by reference? It seems like you are assigning to a variable which was imported through a `use` statement which was not imported by reference. For clarity, we suggest to use a different name or import by reference depending on whether you would like to have the change visibile in outer-scope. Change not visible in outer-scope $x = 1; $callable = function() use ($x) { $x = 2; // Not visible in outer scope. If you would like this, how // about using a different variable name than $x? }; $callable(); var_dump($x); // integer(1) Change visible in outer-scope $x = 1; $callable = function() use (&$x) { $x = 2; }; $callable(); var_dump($x); // integer(2) Loading history...
