How can the use of backticks instead of ticks in SQL queries improve data insertion accuracy in PHP?

Using backticks instead of ticks in SQL queries can improve data insertion accuracy in PHP by properly escaping column and table names. This is important because some column or table names may be reserved keywords in SQL, causing syntax errors when used without backticks. By using backticks, we ensure that the column and table names are treated as identifiers rather than keywords, thus preventing any potential syntax errors during data insertion. 

<?php
// Connect to 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);
}

// Insert data into table using backticks for column names
$sql = "INSERT INTO `users` (`name`, `email`) VALUES ('John Doe', 'john.doe@example.com')";

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

$conn->close();
?>
