Problems I faced and solutions which worked
1. mysql not starting - https://stackoverflow.com/questions/18177148/xampp-mysql-does-not-start
2. php version on xampp - https://stackoverflow.com/questions/49463762/how-to-know-the-version-of-php-is-used-on-xampp
3. phpmyadmin not working - https://stackoverflow.com/questions/52522461/i-changed-the-phpmyadmin-mysql-port-number-and-now-i-cant-log-in
4. problem while connecting to databse:
> servername should be the server phpmyadmin is running . Make sure to include the port 3307(in case changed)
```php
";
/*ways to connect to msql database
1.MySQLi extension
2.PDO
*/
//create a database connection
$servername = "127.0.0.1:3307";//default
$username = "root";
$password = "";//this is default password of xampp
//$database = "codephp";
//create a connection
$conn = mysqli_connect($servername, $username, $password);
//die if connection was not successful
if(!$conn){
die("Sorry we failed to connect: ". mysqli_connect_error());
}
else{
echo "Connection was successful
";
}
?>
```
>adding port number after localhost is another way
