Question

I have a table that looks like the following;

id     header
1      fruit
4      header_example
9      test
13     money

I then have an array that used to contain each of the id’s, but I remove one. I now for example, have an array that looks like this:

array = [1, 9, 13]

How would I look at that array, and determine that the row with id=4 should be deleted?

Thanks!

Answer 1

On the MySQL side, you could just run this, using php to output the array contents into the IN clause:

DELETE FROM table WHERE id NOT IN ( <array contents> )

On the PHP side, you could generate the appropriate contents:

' . implode(', ', $arr) . '
