### RemoveDefaultFromImplicitlyRequiredParamRector

[](#removedefaultfromimplicitlyrequiredparamrector)

This rector removes default values from function/method parameters when they are followed by required parameters, making the code more explicit and preventing potential runtime errors.

**What it does:**

- Removes default values from parameters that are implicitly required (have required parameters after them)
- Adds nullable types (`?type` or `|null`) to parameters that had `null` as their default value
- Preserves default values only for trailing optional parameters

**Example transformation:**

```
// Before
class Example
{
    public function __construct(string $a = null, string $b)
    {
    }
}

// After
class Example
{
    public function __construct(?string $a, string $b)
    {
    }
}
```

**More complex example:**

```
// Before
public function method(
    string $a = 'default',
    string $b,
    string $c = null,
    string $d,
    string $e = 'end'
)

// After
public function method(
    string $a,
    string $b,
    ?string $c,
    string $d,
    string $e = 'end'
)
```
