* Disallow overwriting variables with `foreach` key and value variables. | | `switchConditionsMatchingType` | Types in `switch` condition and `case` value must match. PHP compares them loosely by default and that can lead to unexpected results. | | `dynamicCallOnStaticMethod` | Check that statically declared methods are called statically. | | `disallowedEmpty` | Disallow `empty()` - it's a very loose comparison (see [manual](https://php.net/empty)), it's recommended to use more strict one. | | `disallowedShortTernary` | Disallow short ternary operator (`?:`) - implies weak comparison, it's recommended to use null coalesce operator (`??`) or ternary operator with strict condition. | | `noVariableVariables` | Disallow variable variables (`$$foo`, `$this->$method()` etc.). | -| `overwriteVariablesWithLoop` | Disallow overwriting variables with foreach key and value variables. | | `checkAlwaysTrueInstanceof`, `checkAlwaysTrueCheckTypeFunctionCall`, `checkAlwaysTrueStrictComparison` | Always true `instanceof`, type-checking `is_*` functions and strict comparisons `===`/`!==`. These checks can be turned off by setting `checkAlwaysTrueInstanceof`, `checkAlwaysTrueCheckTypeFunctionCall` and `checkAlwaysTrueStrictComparison` to false. | | | Correct case for referenced and called function names. | | `matchingInheritedMethodNames` | Correct case for inherited and implemented method names. |
