What potential issues or errors could arise when inserting an array into a database using PHP?

One potential issue that could arise when inserting an array into a database using PHP is that the array data may not be properly formatted for insertion into the database. To solve this issue, you can use PHP's implode function to convert the array into a comma-separated string before inserting it into the database. 

// Assume $array is the array you want to insert into the database
$data = implode(",", $array);

// Insert the data into the database
$sql = "INSERT INTO table_name (column_name) VALUES ('$data')";
$result = mysqli_query($conn, $sql);

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