What role does the SELECT statement play in PHP scripts that interact with MySQL databases, and why is it important for displaying table data?

The SELECT statement in PHP scripts interacting with MySQL databases is crucial for retrieving data from a table. It allows you to specify which columns to fetch, filter the results with conditions, and order the data as needed. This statement is essential for displaying table data as it retrieves the information that needs to be shown to the user. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Select data from a table
$sql = "SELECT column1, column2 FROM table_name WHERE condition = 'value'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Column 1: " . $row["column1"]. " - Column 2: " . $row["column2"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
