How can the number of indexes in a database impact the insertion of large data sets in PHP?

Having a large number of indexes in a database can slow down the insertion of large data sets in PHP because each index needs to be updated every time a new row is inserted. To improve performance, you can temporarily disable the indexes before inserting the data and then re-enable them afterwards.

// Disable indexes
mysqli_query($connection, 'ALTER TABLE table_name DISABLE KEYS');

// Insert large data set
// ...

// Re-enable indexes
mysqli_query($connection, 'ALTER TABLE table_name ENABLE KEYS');
