    public function __construct(){

    }

    //Pega a id passada pelo usuario e atribui ao $idAnime

       $resposta = curlSearch($this->urlMal,'get');

       if($resposta[1] != 200){
           return $resposta[1];
       }else{
           $resposta = $resposta[0];
           return $resposta;
       }
    }
}

?>

Answer 1

This error means that there is no function run_search, what exists is the function run_search within the class buscaAnimes, lacked to add the $this->:

//Pega a id passada pelo usuario e atribui ao $idAnime
public function get_busca($b){
    $this->idAnime = $b;
    $resposta = $this->run_search();
    return $resposta;
}
