What are common reasons for receiving error messages like "Incorrect integer value" or "Data too long for column" in PHP when dealing with database entries?

These error messages typically occur when trying to insert data into a database column that does not match the expected data type or exceeds the specified length. To resolve this, ensure that the data being inserted matches the column's data type and length constraints. 

// Example of inserting data into a database table with proper data type and length
$connection = new mysqli("localhost", "username", "password", "database");

$name = "John Doe";
$age = 30;

$query = "INSERT INTO users (name, age) VALUES (?, ?)";
$stmt = $connection->prepare($query);
$stmt->bind_param("si", $name, $age);
$stmt->execute();
