How can reserved words in MySQL affect the functionality of PHP scripts when inserting data into a database?

Reserved words in MySQL can affect the functionality of PHP scripts when inserting data into a database because using reserved words as column names can lead to SQL syntax errors. To avoid this issue, it is recommended to use backticks (`) around column names in SQL queries to differentiate them from reserved words. 

<?php
// Assuming $conn is the database connection object
$column1 = "name";
$column2 = "email";

$value1 = "John Doe";
$value2 = "john.doe@example.com";

$sql = "INSERT INTO `table_name` (`$column1`, `$column2`) VALUES ('$value1', '$value2')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
