## Solution
```php

You just need to bypass the filters here. You can see that there are two comparison operators, one just checks the similarity (==), and the other checks the similarity of types (===). I opened the [documentation](https://www.php.net/manual/en/language.operators.comparison.php) and immediately found the answer.
```phpvar_dump(100 == "1e2"); // 100 == 100 -> true```
But we need to bypass one more filter: the presence of the letter "e" in the string. Simple as it is, just make it uppercase. As a result, we got such a request:
```urlhttp://challs.xmas.htsp.ro:3000/?param1=1E2&param2=100```
