PhpCodeFixer

PhpCodeFixer - a console scanner that checks compatibility of your code with new interpreter versions.

PhpCodeFixer finds: - Usage of deprecated functionality (functions / variables / ini-directives / constants). - Usage of functions with changed behavior. - Usage of reserved identifiers in newer versions.

It literally helps you fix code that can fail after migration to newer PHP version.

Usage

To scan your files or folder launch phpcf and pass file or directory names.

Usage:
    phpcf [-t|--target [TARGET]] [-e|--exclude [EXCLUDE]] [-s|--max-size [MAX-SIZE]] [--file-extensions [FILE-EXTENSIONS]] [--skip-checks [SKIP-CHECKS]] [--output-json [OUTPUT-JSON]] [--] <files> (<files>)...

Arguments:
    files                                    Which files you want to analyze (separate multiple names with a space)?
  
Options:
    -t, --target[=TARGET]                    Sets target PHP interpreter version. [default: "7.3"]
    -e, --exclude[=EXCLUDE]                  Sets excluded file or directory names for scanning. If need to pass few names, join it with comma.
    -s, --max-size[=MAX-SIZE]                Sets max size of php file. If file is larger, it will be skipped. [default: "1mb"]
        --file-extensions[=FILE-EXTENSIONS]  Sets file extensions to be parsed. [default: "php, php5, phtml"]
        --skip-checks[=SKIP-CHECKS]          Skip all checks containing any of the given values. Pass a comma-separated list for multiple values.
        --output-json[=OUTPUT-JSON]          Path to store json-file with analyze results.  If '-' passed, json will be printed on stdout.

• By providing additional option `--target` you can specify version of PHP to perform less checks. Available target versions: 5.3, 5.4, 5.5, 5.6, 7.0, 7.1, 7.2, 7.3. A larger version includes rules for checking from all previous.
• By providing `--exclude` option you can exclude specific folders or files from analyze. For example, `--exclude vendor` will prevent checking third-party libraries.
• By providing `--skip-checks` option you can exclude specific checks from analyze.
• If your files has unusual extension, you can specify all exts by `--file-extensions` option. By default, it uses `php`, `phtml` and `php5`.
• If you need to generate machine-readable analyze result, use `--output-json` option to specify path to store json or `--output-json=-` to print json to stdout.

Total problems: 28

Replace Suggestions:
1. Don't use function mcrypt_generic_end() => Consider replace to mcrypt_generic_deinit().
2. Don't use function read_exif_data() => Consider replace to exif_read_data().
3. Don't use function each() => Consider replace to foreach().
4. Don't use ini mbstring.http_output => Consider replace to default_charset.

Notes:
1. Usage piet() (@call_with_passing_by_reference): Call with passing by reference is deprecated. Problem is "&$hoho"
2. Usage preg_replace() (@preg_replace_e_modifier): Usage of "e" modifier in preg_replace is deprecated: "asdasdsd~ie"
3. Usage password_hash() (@password_hash_salt_option): "salt" option is not secure and deprecated now
4. Usage mb_ereg_replace() (@mb_ereg_replace_e_modifier): Usage of "e" modifier in mb_ereg_replace is deprecated: ""msre""
5. Usage assert() (@assert_on_string): You should avoid using string code: "'false'"
6. Usage parse_str() (@parse_str_without_argument): Call to parse_str() without second argument is deprecated
7. Usage define() (@define_case_insensitive): Case-insensitive flag of define() is deprecated, use original constant name in your code
