Why am I getting a 'Warning: mysqli_query() expects parameter 1 to be mysqli, resource given' error?

Warning: mysqli_query() Parameter Error Resolved

Encountering the warning "Warning: mysqli_query() expects parameter 1 to be mysqli, resource given" typically indicates a mismatch between the mysqli and mysql extensions. Here's how to resolve it:

In your code, you've inadvertently mixed mysqli and mysql extensions. To fix this, ensure consistency throughout your script. Replace the following lines with their mysqli equivalents:

$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");  

With:

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");

mysqli_select_db($myConnection, "mrmagicadam") or die ("no database");   

By switching to mysqli functions, you take advantage of its improved capabilities and resolve the error. Remember, maintain consistency between the mysqli and mysql extensions throughout your code.
