使用php创建MySQL数据库

Question

我正在尝试使用database创建SQL并插入PHP个文件

但未创建database。

此问题完全不同于：Can I mix MySQL APIs in PHP?

由于我没有因MySQL API而遇到麻烦。

我试过了：

$link = mysqli_connect("host", "user", "pass");

// Check connection
if($link === false){
    die("ERROR: Could not connect. " . mysqli_connect_error());
}
 $usre= "databasename";
 $db_uname = "user";
 $us ="_";
 $db_uname_f = $usre;
// Attempt create database query execution
$sql = "CREATE DATABASE $db_uname_f";
if(mysqli_query($link, $sql)){
    // Name of the file
$filename = 'ch/user_database.sql';
// MySQL host
$mysql_host = 'host';
// MySQL username
$mysql_username = 'user';
// MySQL password
$mysql_password = 'pass';
// Database name
$mysql_database = $db_uname_f;

// Connect to MySQL server
mysql_connect($mysql_host, $mysql_username, $mysql_password) or die('Error connecting to MySQL server: ' . mysql_error());
// Select database
mysql_select_db($mysql_database) or die('Error selecting MySQL database: ' . mysql_error());

// Temporary variable, used to store current query
$templine = '';
// Read in entire file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line)
{
// Skip it if it's a comment
if (substr($line, 0, 2) == '--' || $line == '')
    continue;

// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';')
{
    // Perform the query
    mysql_query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysql_error() . '<br /><br />');
    // Reset temp variable to empty
    $templine = '';
}
}
 $locat = "ch/install_new_user.php?user=";
$locatione = $locat.$usre;
header("Location: $locatione");

} else{



    $msg = "
                   <div class='alert alert-alert'>
                   <button class='close' data-dismiss='alert'>&times;</button>
                      Your Account <strong>$usre</strong> is Now Verified, please wait for email for start operating.
                   </div>
                   ";
}

// Close connection
mysqli_close($link);

注意：适用于wamp。
