When use str_replace with arrays there's strange behavior

https://3v4l.org/maNqa


```php
var_dump(str_replace(
            [
                ',',
                '.',
            ],[
                '.',
                ',',
            ],
            '1.2,3'
        ));
```

This code is expected to replace all commas with dots and all dots with
commas, however in result we get all commas.
