PHP to connect to MySQL configuration in windows Sometimes we encounter strange problems: the apache server can be enabled normally, the php code can also run normally, and MySQL can also be used, but the error when connecting to MySQL using the PHP code is as follows:

Use pdo to connect to the test code

try {

$con= new PDO("mysql:host=localhost","root","password");

echo " Connection successful";

}

catch(PDOException $e)

{

echo $e->getMessage();

}

An abnormal prompt could not be found during operation

Use mysqli_connect to connect the test code

$con= mysqli_connect("localhost","root1","password");

if ($con->connect_error) {

die("Connection failed: " . mysqli_connect_error());

}

echo "Connection successful";

?>

The statements in php.ini, extension=mysqli and extension=pdo_mysql, have been removed (removal means letting PHP enable this extension).

Use phpinfo() to check - write a file phpinfo.php (the content is ), then put this file in the website directory and open it in the browser

Loaded Configuration File (none),
