How can the issue of syntax errors in SQL queries, such as the one mentioned in the forum thread, be avoided when using shuffle()?

Issue: Syntax errors in SQL queries can be avoided by properly sanitizing input data before constructing the query. When using shuffle() to randomize an array of values, make sure to escape any special characters to prevent SQL injection attacks. Fix: To avoid syntax errors in SQL queries when using shuffle(), you can sanitize the input data using prepared statements. Here is an example code snippet that demonstrates how to safely shuffle an array of values and insert them into a database using PDO: 

<?php
// Sample array of values
$values = ['value1', 'value2', 'value3', 'value4'];

// Shuffle the array
shuffle($values);

// Connect to the database using PDO
$dsn = 'mysql:host=localhost;dbname=your_database';
$username = 'your_username';
$password = 'your_password';
$pdo = new PDO($dsn, $username, $password);

// Prepare the SQL query using a prepared statement
$stmt = $pdo->prepare("INSERT INTO your_table (column_name) VALUES (:value)");

// Bind and execute the shuffled values
foreach ($values as $value) {
    $stmt->bindParam(':value', $value);
    $stmt->execute();
}

echo "Values inserted successfully!";
?>
