php error unable to output data?

Question

PHP

Hello. Here's the code.

Here is such an error.
Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in D:\PROJECTS\myproject_new\OpenServer\domains\dsdsfsd\index.php on line 110 I
recently started watching a video on php and as always everything works smoothly without any problems. There, the truth is mysql_ and I have to somehow redo it on mysqli_ and now I came across an error.

Answer 1

if (!$result) {
    printf("Errormessage: %s\n", mysqli_error($connect));
}

Answer 2

your connection is not established, in the code it should be

if (!$connect) {
echo 'Can\'t connect to database. Err: '.mysqli_connect_error();
exit;
}

1) the condition must contain a shutdown instruction die, exit, trigger_error or exception, otherwise the code will continue to be executed and Warning will continue to pour
in 2) you must use mysqli_connect_error () instead of mysqli_error ()

Answer 3

Use the class to work with MySql !
