Question

注意：未定义索引：页面位于C：\ xampp \ htdocs \ Project \ indexx.php中   第18行

注意：未定义索引：C：\ xampp \ htdocs \ Project \ indexx.php中的look4   在第19行

警告：mysqli_fetch_array（）期望参数1为mysqli_result，   第23行的C：\ xampp \ htdocs \ Project \ indexx.php中给出的布尔值

警告：mysqli_fetch_assoc（）期望参数1为mysqli_result，   在第30行的C：\ xampp \ htdocs \ Project \ indexx.php中给出的布尔值

请帮助，我只是想不通。附言我是初学者，请放心，我笑
