What are some considerations for PHP developers when deactivating multiple records in a database table based on specific criteria?

When deactivating multiple records in a database table based on specific criteria, PHP developers need to carefully construct their SQL query to target the correct rows for deactivation. They should also ensure that the criteria used for deactivation is accurate and meets the desired conditions. Additionally, it's important to handle any potential errors that may arise during the deactivation process.

php 
// Establish a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Construct SQL query to deactivate records based on specific criteria
$criteria = "your_criteria_here";
$sql = "UPDATE your_table SET status = 'inactive' WHERE $criteria";

// Execute the SQL query
if ($conn->query($sql) === TRUE) {
    echo "Records deactivated successfully";
} else {
    echo "Error deactivating records: " . $conn->error;
}

// Close the database connection
$conn->close();
