How to Properly Bind an Array of IDs to a MySQL IN Statement Using PDO?

PDO Binding Values for MySQL IN Statement

This question addresses binding an array of ID's to a PDO statement for use in a MySQL IN statement. The issue arises when the comma-separated values in the array are treated as a single string rather than individual values.

Solution:

The suggested solution is to use the find_in_set function in the WHERE clause. However, there are other options available.

Option 1: Find_in_set

select users.id
from users
join products
on products.user_id = users.id
where find_in_set(cast(products.id as char), :products)

This method is suitable for relatively small data sets, as it can have performance implications for larger databases.

Option 2: User Defined Function

A user defined function can be created to split the comma-separated list of values. This is a more scalable solution for large data sets. Resources on creating such a function can be found in the provided link:
