When working with an import script for an online shop, what considerations should be made for setting flags in a SQL database using PHP?

When working with an import script for an online shop, it's important to consider setting flags in a SQL database to track the status of imported data. This can help in monitoring the progress of the import process, identifying any errors, and ensuring data integrity. To set flags in a SQL database using PHP, you can use SQL queries to update a specific column in the database table based on certain conditions or events during the import process.

// Assuming you have established a database connection

// Set a flag to indicate the start of the import process
$sql = "UPDATE import_status SET status = 'in_progress' WHERE id = 1";
$result = mysqli_query($conn, $sql);

// After successfully importing data, set a flag to indicate completion
$sql = "UPDATE import_status SET status = 'completed' WHERE id = 1";
$result = mysqli_query($conn, $sql);

// If there are any errors during the import process, set a flag to indicate failure
$sql = "UPDATE import_status SET status = 'failed' WHERE id = 1";
$result = mysqli_query($conn, $sql);
