Are there additional measures that need to be taken besides using mysql_real_escape_string() to prevent SQL injections in PHP?

To prevent SQL injections in PHP, in addition to using mysql_real_escape_string(), it is recommended to use prepared statements with parameterized queries. This method separates the SQL query logic from the data input, making it impossible for an attacker to inject malicious code into the query. 

// Using prepared statements to prevent SQL injections
$stmt = $mysqli->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);

$username = $_POST['username'];
$stmt->execute();
$result = $stmt->get_result();

while ($row = $result->fetch_assoc()) {
    // Process data
}

$stmt->close();
$mysqli->close();
