The error message "Unknown column 'fleet1' in field list" indicates that there is a typo in the column name specified in the SQL query. To solve this issue, you need to correct the column name to match the actual column name in the database table. 

<?php
// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Check connection
if ($connection === false) {
    die("ERROR: Could not connect. " . mysqli_connect_error());
}

// Query to select data from a table
$sql = "SELECT column1, column2 FROM table_name WHERE fleet = 'fleet1'";

// Execute the query
$result = mysqli_query($connection, $sql);

// Check if query was successful
if ($result) {
    // Fetch result as an associative array
    while ($row = mysqli_fetch_assoc($result)) {
        // Process the data
    }
} else {
    echo "ERROR: Could not able to execute $sql. " . mysqli_error($connection);
}
