In the example below, the first command tells PHP_CodeSniffer to check the `myfile.inc` file for coding standard errors while the second command tells PHP_CodeSniffer to check all PHP files in the `my_dir` directory.

You can also specify multiple files and folders to check. The command below tells PHP_CodeSniffer to check the `myfile.inc` file and all files in the `my_dir` directory.

After PHP_CodeSniffer has finished processing your files, you will get an error report. The report lists both errors and warnings for all files that violated the coding standard. The output looks like this:

By default, PHP_CodeSniffer will print a complete list of all errors and warnings it finds. This list can become quite long, especially when checking a large number of files at once. To print a summary report that only shows the number of errors and warnings for each file, use the `--report=summary` command line argument. The output will look like this:
