mysqli_select_db() : This function is used to connect to particular database in you server. After connecting front end to database, the next step is to connect to desired database because a back-end (MySql) may have multiple databases in it. Hence using mysqli_select_db() function you specify which database should be connected to your connection variable. This function has two parameters namely a) connection variable b) database name
Exmaple: mysqli_select_db($conn,”databasename”) mysqli_query() : This function is used to run the query of MySql such as inserting a new record, selecting a required record etc. This function has two parameters a) connection variable b) query string
Example: mysqli_query($conn, $sql) or die(mysqli_error())
- mysql_connect() : This function of PHP is the main function used to connect your front-end to MySql back end. There are three parameters for this function namely:
a) server-name
b) username
c) password
For example if you want to connect to localhost then the format is:
mysqli_connect(“localhost”,”root”,””)
Default Localhost Credentials :
- Server Name: “localhost”
- User Name: “root”
- Password: null
Exmaple: mysqli_select_db($conn,”databasename”)
Example: mysqli_query($conn, $sql) or die(mysqli_error())
