How to Bind Values for MySQL IN Statement Using PDO

Binding an array of values to a PDO statement for use in a MySQL IN statement can be tricky. When done incorrectly, the statement may execute with the values concatenated as a single string, rather than as individual values.

To bind values correctly, avoid using implode() to create a comma-separated string. Instead, consider using the following methods:

• Construct the Query Manually: Compose the query string yourself, manually inserting the comma-separated values within the IN statement.
• Use find_in_set(): Utilize the find_in_set() function to match a value against a comma-separated string within a WHERE clause. This method may have performance drawbacks for large datasets.
• Create a User Defined Function (UDF): Write your own UDF to split the comma-separated string into individual values. This option provides the best performance for queries with frequent IN(...) clauses.
