Can I combine the values in the database with an comma (,) instead of next line?

Can I combine the values in the database with an comma (,) instead of next line?

Cause I am using the following code to check in PHP if one thread match with another thread:

PHP Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

<?php $id1 = '1,2,3,4,5,6,7,8,9,10'; // the values from thread_field_data where tid=1 $id2 = '10,11,12,13,14,15,16'; // the values from thread_field_data where tid=2 // splitting them up into an array $one = explode(',', $id1); $two = explode(',', $id2); // making the check $result = count(array_intersect($one, $two)); if($result > 0) { echo 'Something matched!'; } ?>

I don't know how to do that with newlines?
