What is the significance of using mysql_real_escape_string in PHP scripts, even if only administrators have access?

Using mysql_real_escape_string in PHP scripts is significant because it helps prevent SQL injection attacks, where malicious SQL queries are injected into the script. Even if only administrators have access, it's important to sanitize user input to ensure the security of the application. By using mysql_real_escape_string, special characters in user input are escaped, making it safe to use in SQL queries. 

// Example of using mysql_real_escape_string to sanitize user input
$user_input = $_POST['user_input'];
$escaped_input = mysql_real_escape_string($user_input);

// Use $escaped_input in your SQL query
$query = "SELECT * FROM users WHERE username = '$escaped_input'";
$result = mysql_query($query);
