Database Connection in PHP with MySQL in Xampp Code
Before you create a phpmyadmin database connection using a PHP script, you must know about the PHP MySQL connection function:
mysqli_connect
PHP provides mysql_connect() function to open a database connection. This function takes five parameters and returns a MySQL link identifier on success or FALSE on failure.
Syntax
mysqli_connect(host,username,password,new_link,client_flag);
Host
The hostname that runs the database server If not specified, the default value will be localhost.
username
Username accessing the database If not specified, the default will be the name of the user who is the owner of the server process.
password
The default value is defined by MySQL default password. In SQL secure mode, this parameter is ignored and a blank password is used.
new_link
If mysqli_connect () is called with other arguments, no new connection will be established. Instead, the identifier of the already open connection will be returned.
client_flags
- MYSQL_CLIENT_SSL – Use SSL encryption.
- MYSQL_CLIENT_COMPRESS – Use Compression Protocol.
- MYSQL_CLIENT_IGNORE_SPACE – Allow the location after the function names.
- MYSQL_CLIENT_INTERACTIVE – Allow passive seconds of idle time before closing connection.
