我正在尝试使用psalm static analysis tool for PHP。据我了解,该工具可以告诉我有关unused methods in my codebase的信息。但是,如果我创建一个简单的测试文件
#File: src/test.php
<?php
class A {
private function foo() : void {}
}
new A();
然后运行psalm
$ ./vendor/bin/psalm --find-dead-code src/test.php
Scanning files...
Analyzing files...
------------------------------
No errors found!
------------------------------
Checks took 0.16 seconds and used 32.694MB of memory
Psalm was able to infer types for 100% of the codebase
或psalter
,
$ ./vendor/bin/psalter --find-unused-code --dry-run --issues=UnusedMethod src/test.php
Scanning files...
Analyzing files...
------------------------------
No errors found!

Checks took 0.05 seconds and used 29.214MB of memory
Psalm was able to infer types for 100% of the codebase
没有发现错误。
为什么诗篇找不到未使用的方法foo
?是否需要其他配置?还是我误会了这个工具的作用?我的psalm.xml
文件在下面。

答案 0 :(得分:4)
此处的诗篇创建者-死代码检测仅在分析整个项目时才检测未使用的类和方法-例如./vendor/bin/psalm --find-dead-code
,省略src/test.php
。
虽然私有方法和属性是一种特殊情况(可以在不检查整个项目的情况下推断出它们的未使用状态),但对于公共/受保护的方法和属性,则必须消耗所有内容。

According to the documentation,您将希望使用--find-dead-code
的{{1}}参数:
psalm
输出:
./vendor/bin/psalm --find-dead-code foo.php
