How can the data type of database columns impact the insertion of values in PHP scripts?

The data type of database columns can impact the insertion of values in PHP scripts because if the data being inserted does not match the data type of the column, it can result in errors or unexpected behavior. To solve this issue, you should ensure that the data being inserted matches the data type of the column by properly validating and sanitizing the input before insertion.

// Example code snippet to insert data into a database table with proper data type validation

// Assuming $db is your database connection object

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

// Validate and sanitize input data
$name = mysqli_real_escape_string($db, $name);
$age = (int)$age; // Convert age to integer

// Insert data into database table
$query = "INSERT INTO users (name, age) VALUES ('$name', $age)";
$result = mysqli_query($db, $query);

if ($result) {
    echo "Data inserted successfully!";
} else {
    echo "Error inserting data: " . mysqli_error($db);
}
