it shows following error:

warning: mysqli_query() expects parameter 1 mysqli, boolean given in c:\program files\easyphp-devserver-17\eds-www\mark\upload.php on line 51

the problem $db_select should post see can see mysqli doc see more: http://php.net/manual/en/mysqli.query.php

look @ $link in below example.

<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world");  /* check connection */ if (mysqli_connect_errno()) {     printf("connect failed: %s\n", mysqli_connect_error());     exit(); }  /* create table doesn't return resultset */ if (mysqli_query($link, "create temporary table mycity city") === true) {     printf("table mycity created.\n"); }
