通过将代码从MySQL更改为MySQLi，我遇到了一些问题。 我的网站基于mysql.php。我想我没事，但是我收到一些错误消息：
警告：mysqli_query（）期望参数1为mysqli，在第76行的/customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php中给出的null警告：mysqli_real_escape_string （）期望参数1为mysqli，在第150行的/customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php中给出的null警告：mysqli_query（）期望参数1为是mysqli，在第54行的/customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php中给出的警告：mysqli_real_escape_string（）期望参数1是mysqli，在中给出的null第150行的/customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php警告：mysqli_query（）期望参数1为mysqli，/ customers / 6 / b中给出的null第54行上的/7/ssd-go.de/httpd.www/dev/int/mysql.php警告：mysqli_real_escape_string（）期望参数1为mysqli，在/ customers / 6 / b / 7 / ssd-go中指定为null第150行的.de / httpd.www / dev / int / mysql.php警告：mysqli_query（）期望参数1为mysqli，在/customers/6/b/7/ssd-go.de/httpd.www中给出的null /dev/int/mysql.php在第54行警告：mysqli_real_escape_string（）期望参数1为mysqli，在第150行的/customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php中给出的null为警告：mysqli_query （）期望参数1为mysqli，在第54行的/customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php中给出的null警告：mysqli_real_escape_string（）期望参数1为是mysqli，在第150行的/customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php中给出的null警告：mysqli_query（）期望参数1为mysqli，在中给出的null /customers/6/b/7/ssd-go.de/httpd.www/dev/int/mysql.php，第54行`
所以我还向您展示了我的mysql.php代码：
