I have searched the net and so far what I have seen is that you can use mysql_ and mysqli_ together meaning:
<?php
$con=mysqli_connect("localhost", "root" ,"" ,"mysql");
if( mysqli_connect_errno( $con ) ) {
echo "failed to connect";
}else{
echo "connected";
}
mysql_close($con);
echo "Done";
?>
or
<?php
$con=mysql_connect("localhost", "root" ,"" ,"mysql");
if( mysqli_connect_errno( $con ) ) {
echo "failed to connect";
}else{
echo "connected";
}
mysqli_close($con);
echo "Done";
?>
Are valid but when I use this code what I get is:
Connected
Warning: mysql_close() expects parameter 1 to be resource, object given in D:\************.php on line 9
Done
For the first and the same except with mysqli_close(). For the second one.
What is the problem? Can't I use mysql_ and mysqli together? Or is it normal? Is the way I can check if the connections are valid at all? (the if(mysq...))
