Please help me to see why a piece of database management code is invalid.

Please help me see why a piece of database management code is invalid & lt ;? Php $ dbcon & nbsp; = & nbsp; mysql_connect ("localhost", "×××", "××××"); if (! $ Dbcon) {& nbsp; & nb, please help me see why a piece of database management code is invalid

 $dbcon = mysql_connect("localhost","××××","×××××");
if(!$dbcon)
{
    die('could not connect: ' . mysql_error());
}
echo "mysql connected\n";
mysql_query("CREATE DATABASE soap_calc",$dbcon);
mysql_select_db("soap_calc",$dbcon);
$sql = "CREATE TABLE oils
(
ID int NOT NULL AUTO_INCREMENT,
CN_Name varchar(15),
EN_Name varchar(30),
SAP decimal(5,3),
SAP_NaOH decimal(5,3),
Non_Sapon decimal(5,3),
Iodine decimal(10,3),
PRIMARY KEY (ID)
)";
mysql_query($sql,$dbcon);

//read items from file
$file = fopen("oiltable", "r");
while(!feof($file))
{
    fscanf($file,"%s %s %s %s %s \n",$CNN,$ENN,$NAOH,$KOH,$INS);
    mysql_query("INSERT INTO oils (CN_Name,EN_Name,SAP,SAP_NaOH)
                 VALUES ('$CNN','$ENN','$KOH','$NAOH')");
}
mysql_close($dbcon);
echo "db finished\n";
?>

I put this. php file under the/var/www directory and execute it in the browser.
Echo "mysql connected \ n"; and echo "db finished \ n"; are all executed.
However, I used phpmyadmin to view the database and found that no soap_calc database was created.
I was just getting started with PHP. please give me some advice. thank you. Share with php mysql:
------ Solution --------------------
Reference:

Print_r (mysql_query ("create database soap_calc", $ dbcon); [/coder]

Check if there are any mistakes

[Code = php] print_r (mysql_query ("create database soap_calc", $ dbcon ));

The mouse cursor is always on the laptop keyboard. it's wrong. check this section.
------ Solution --------------------
Mysql_query ("create database soap_calc", $ dbcon) or die (mysql_error ());
Look, it is estimated that there is no permission
