PHP configures mysql and how to test the successful configuration of the database_PHP tutorial

PHP configuration mysql and how to test the success of configuring the database. Friends in need can refer to it.

If you are configuring php mysql apache for the first time, how do we test whether php connects to the database successfully? Just create a test.php file and save the following code to the file.

If it prompts that the mysql_connect function is not defined, we can configure it in php.ini as shown below

The code is as follows

代码如下	复制代码
$link=mysql_connect("localhost","root","12345"); //12345改成你的mysql密码 if(!$link) echo "失败!"; else echo "成功!"; mysql_close(); ?>

Copy code

$link=mysql_connect("localhost","root","12345"); //Change 12345 to your mysql password

if(!$link) echo "Failed!";

else echo "Success!";

mysql_close();

?>

Open http://localhost/test.php in the browser

If you enter

Success means your configuration is successful. If it fails, we can use mysql_connect("localhost","root","12345") or die( mysql_error()); and there will be an error message.

;extension=php_mysql.dll ;extension=php_mysqli.dll

Remove the previous; extension=php_mysql.dll extension=php_mysqli.dll Then restart apache
