Release 4.8.0 introduced a bug in baseline generation. This release should fix it!
Detect more unused code
Features
New literal-string type
Inspired by the is_literal RFC we've added a new literal-string type.
The type will be most useful to annotate functions and methods that take SQL. In those methods you generally don't want any code that is not part of your app, e.g.
// passes type checks
execute_sql(
'SELECT * FROM foo WHERE id = :id',
[':id' => $id]
);
// fails
execute_sql(
'SELECT * FROM foo WHERE id = "' .$id . '"'
);
Psalm’s taint analysis can also help detect this general class of issues, but a literal-string type allows the type-checker to provide guarantees much earlier in the process.
htmlentities can be used to strip some harmful characters in strings, but not all of them (by default).
Psalm has a new issue TaintedTextWithQuotes to help detect strings that might not have HTML tags but can have harmful Javascript.
Detect unused return values
When running with the --find-unused-code flag, Psalm already detects a lot of unnecessary code, including unused public and private methods, unused properties and unused variables.
Now Psalm will also flag unused return values — where a function returns something, but nowhere that calls the given function actually uses the returned value.
