Have you looked into displaying MySQL errors? More information can be found here:

http://php.net/manual/en/mysqli-driver.report-mode.php

 

Also note that your query is susceptible to SQL injection attacks. At some point, if you haven't already, you'll want to look into prepared statements.

 

Lastly, you should double check what the mysqli_fetch_array() function returns: 

http://php.net/manual/en/mysqli-result.fetch-array.php

Side note: if you don't need the numeric array that's returned, in addition to the associative array, by the mysqli_fetch_array() function, you could use mysqli_fetch_assoc() instead. More information can be found here:

http://php.net/manual/en/mysqli-result.fetch-assoc.php

 

Based on the following quote from the manual, mysqli_fetch_array() may not return the associative array in some cases. I imagine it depends on the server setup...

 

Fetch a result row as an associative, a numeric array, or both

 

If that's the case, mysqli_fetch_assoc() is going to be the safer choice.
