Challenges I ran into

First of all i'm kind of a newbie to PHP and MySQL. My php script connected to database successfully but i have problem with executing query. Problem is that my script went normally until 'echo " A ";' and than stops. Script never reach line 'echo " B ";'.Sometimes your MySQLi code produces an error like mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given..., Call to a member function bind_param()... or similar. Or even without any error, but the query doesn't work all the same. It means that the query failed to execute.Every time a query fails, MySQL has an error message that explains the reason. In the older PHP versions such errors weren't transferred to PHP.The MySQL server has gone away (error 2006) has two main causes and solutions,Server timed out and closed the connection. To fix, check that wait_timeout mysql variable in my.cnf configuration file is large enough, eg wait_timeout = 28800,Server dropped an incorrect or too large packet. If mysqld gets a packet that is too large or incorrect, it assumes that something has gone wrong with the client and closes the connection. To fix, to increase the maximal packet size limit max_allowed_packet in my.cnf file, eg. set max_allowed_packet = 128M, then restart your MySQL server: sudo /etc/init.d/mysql restart,Database server ran out of space. This can occur when performing an update to the Matomo database that requires DB Schema changes (Especially for large databases),, Open our browser put inside( "http://localhost/Online examination system/")at that time we can see the web portal,...............................................................................................................................................................................................................................................................................................................................................................................................................................
