What potential issues can arise when using INSERT INTO within a while loop in PHP for database operations?

When using INSERT INTO within a while loop in PHP for database operations, potential issues can arise due to multiple insertions being executed in quick succession. This can lead to performance issues, database locks, or duplicate entries. To solve this problem, you can prepare the INSERT statement outside the loop and then bind the variables inside the loop for each iteration. 

// Prepare the INSERT statement outside the loop
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");

while ($condition) {
    // Bind the variables inside the loop for each iteration
    $value1 = $some_value;
    $value2 = $another_value;

    $stmt->bindParam(':value1', $value1);
    $stmt->bindParam(':value2', $value2);

    $stmt->execute();
}
