Warning: mysqli_query() expects parameter 1 to be mysqli, string given in C:\wamp\www\new_pavani\htdocs\login.php on line 24

我尝试过：



警告：mysqli_query（）要求参数1为mysqli，C：\ wamp \\中给出的字符串第24行\\\ new_pavani \htdocs\login.php

通话栈

＃时间记忆功能位置

1 0.0010 142944 {main}（）..：\ tlogin.php：0

2 0.0070 151616 mysqli_query（）..：\ logo.php：24



（！ ）警告：mysqli_num_rows（）期望参数1为mysqli_result，在第26行的C：\ wamp \ www。\\ new_pavani \htdocs \ login.php中给出null

调用堆栈

＃时间记忆功能位置

1 0.0010 142944 {main}（）.. \ login.php：0

2 0.0100 152024 mysqli_num_rows（） .. \login.php：26

What I have tried:

Warning: mysqli_query() expects parameter 1 to be mysqli, string given in C:\wamp\www\new_pavani\htdocs\login.php on line 24
Call Stack
# Time Memory Function Location
1 0.0010 142944 {main}( ) ..\login.php:0
