Code Inspections in General

This topic lists all PhpStorm code inspections available in General.

You can toggle specific inspections or change their severity level on the Editor | Inspections page of the IDE settings Ctrl+Alt+S.

Inspection	Description	Default Severity
Annotator	Reports problems that are found by language annotators in the result of a batch code inspection run.	Error
Duplicated code fragment	Reports duplicated blocks of code from the selected scope: the same file or the entire project. The inspection features quick-fixes that help you to set the size of detected duplicates, navigate to repetitive code fragments, and compare them in a tool window. The inspection options allow you to select the scope of the reported duplicated fragments and set the initial size for the duplicated language constructs. You can also configure the constructs that you want to anonymize in File \| Settings \| Editor \| Duplicates.	Weak warning
Empty directory	Reports empty directories. Available only from Code \| Inspect Code or Code \| Analyze Code \| Run Inspection by Name and isn't reported in the editor. Use the Only report empty directories located under a source folder option to have only directories under source roots reported.	Disabled
Inconsistent line separators	Reports files with line separators different from the ones that are specified in the project's settings. For example, the inspection will be triggered if you set the line separator to `\n` in Settings \| Editor \| Code Style \| Line separator, while the file you are editing uses `\r\n` as a line separator. The inspection also warns you about mixed line separators within a file.	Disabled
Incorrect formatting	Reports formatting issues that appear if your code doesn't follow your project's code style settings. This inspection is not compatible with languages that require third-party formatters for code formatting, for example, Go or C with CLangFormat enabled.	Disabled
Injected references	Reports unresolved references injected by Language Injections. Example: @Language("file-reference") String fileName = "/home/user/nonexistent.file"; // highlighted if file doesn't exist	Error
Line is longer than allowed by code style	Reports lines that are longer than the Hard wrap at parameter specified in Settings \| Editor \| Code Style \| General.	Disabled
Problematic whitespace	Reports the following problems: Tabs used for indentation when the code style is configured to use only spaces. Spaces used for indentation when the code style is configured to use only tabs. Spaces used for indentation and tabs used for alignment when the code style is configured to use smart tabs.	Disabled
Redundant suppression	Reports usages of the following elements that can be safely removed because the inspection they affect is no longer applicable in this context: `@SuppressWarning` annotation, or `// noinspection` line comment, or `/** noinspection */` JavaDoc comment Example: public class C { // symbol is already private, // but annotation is still around @SuppressWarnings({"WeakerAccess"}) true; void f() { CONST = false; } }	Warning
Syntax error	Reports syntax errors that have been found in the result of a batch code inspection run.	Error
TODO comment	Reports TODO comments in your code. You can configure the format for TODO comments in Settings \| Editor \| TODO. Since syntax highlighting for TODO comments is already provided, this inspection is intended for use in batch mode or on a continuous integration server.	Disabled
