How can a WHERE condition in a MySQL query affect the order of data in the JS output?

When a WHERE condition is used in a MySQL query, it filters the data based on the specified criteria. This can affect the order of the data in the output if the query includes an ORDER BY clause. To ensure that the data is ordered correctly in the JS output, you should include the ORDER BY clause in your MySQL query along with the WHERE condition. 

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

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

// SQL query with WHERE condition and ORDER BY clause
$sql = "SELECT * FROM table_name WHERE column_name = 'criteria' ORDER BY column_name ASC";

if($result = $mysqli->query($sql)){
    // Fetch result rows as an associative array
    while($row = $result->fetch_assoc()){
        // Output data in JS format
        echo "<script>console.log('". json_encode($row) ."');</script>";
    }
    // Free result set
    $result->free();
} else{
    echo "ERROR: Could not execute $sql. " . $mysqli->error;
}

// Close connection
$mysqli->close();
?>
