How to connect to my MySQL Database server using command line and php

To connect to a MySQL database server using the command line, you will need to use the mysql command and provide your login credentials. For example:

mysql -h <hostname> -u <username> -p

Replace <hostname> with the hostname or IP address of the MySQL server, and <username> with the username you want to use to connect to the server. You will be prompted to enter the password for the user.

Once you are connected to the MySQL server, you can use SQL commands to interact with the database.

To connect to a MySQL database server using PHP, you will need to use the mysqli extension. Here is an example of how to connect to a database and run a simple query:

<?php
$hostname = '<hostname>';
$username = '<username>';
$password = '<password>';
$database = '<database>';

// Connect to the database
$conn = mysqli_connect($hostname, $username, $password, $database);

// Check the connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Run a query
$result = mysqli_query($conn, "SELECT * FROM <table>");

// Process the results
while ($row = mysqli_fetch_assoc($result)) {
    // Do something with the row data
}

// Close the connection
mysqli_close($conn);

Replace <hostname>, <username>, <password>, <database>, and <table> with the appropriate values for your MySQL server and database.
