What are common pitfalls when storing different data types in a PHP MySQL database?

One common pitfall when storing different data types in a PHP MySQL database is not properly sanitizing user input, which can lead to SQL injection attacks. To solve this issue, always use prepared statements or parameterized queries to prevent SQL injection. 

// Example of using prepared statements to store different data types in a MySQL database

// Assuming $conn is the MySQL database connection object

// Prepare an INSERT statement
$stmt = $conn->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");

// Bind parameters
$stmt->bind_param("ss", $value1, $value2);

// Set parameter values
$value1 = "string value";
$value2 = 123;

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

// Close the statement
$stmt->close();
