php - How to match entries that have commas?

Get the solution ↓↓↓

Solution:

This is not a recommended practice as it forces the database engine to inspect all rows of your table. It's better to create a permission table where each user that has access to a note are listed separately (make sure to also index the user column).

If you really REALLY have to, you can use theLOCATE string function (assuming MySQL): http://dev.mysql.com/doc/refman/5.5/en/string-functions.html#function_locate

Of course,LOCATE has issues too because it doesn't care about comma delimited stuff, so the "better" approach might beREGEXP: http://dev.mysql.com/doc/refman/5.5/en/regexp.html#operator_regexp
