How can potentially harmful code snippets in various programming languages be safely inserted into a MySQL table in PHP?

When inserting potentially harmful code snippets into a MySQL table in PHP, it is important to sanitize the input to prevent SQL injection attacks. One way to do this is by using prepared statements with parameterized queries. This helps to separate the data from the SQL commands, making it safer to insert the code snippets into the database. 

// Assuming $conn is the database connection object

// Sanitize the potentially harmful code snippet
$codeSnippet = "potentially harmful code snippet";
$codeSnippet = mysqli_real_escape_string($conn, $codeSnippet);

// Prepare the SQL statement using a parameterized query
$stmt = $conn->prepare("INSERT INTO table_name (code_snippet) VALUES (?)");
$stmt->bind_param("s", $codeSnippet);

// Execute the statement
$stmt->execute();
