Why does the ID count increase when using the UPDATE function in PHP with MySQL?
When using the UPDATE function in PHP with MySQL, the ID count may increase because the UPDATE query does not reset the auto-increment value of the ID column. This can lead to gaps in the ID sequence if rows are deleted or updated. To solve this issue, you can reset the auto-increment value of the ID column after running the UPDATE query.
// Run the UPDATE query
// $sql = "UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition";
// mysqli_query($conn, $sql);
// Reset the auto-increment value of the ID column
// $reset_sql = "ALTER TABLE table_name AUTO_INCREMENT = 1";
// mysqli_query($conn, $reset_sql);
