Using WHERE IN Clause to Query MySQL with Array

Given an array of IDs, the goal is to construct a SQL query that checks the values in the WHERE clause using the array values.

To generate the query string, follow these steps:

Step 1: Create the Base Query

SELECT *
FROM galleries

Step 2: Append the WHERE Clause with IN Operator

WHERE id IN (?,?,?,...)

• The number of question marks соответствует the length of the array.

Step 3: Parameterize the Values

• Prepare the SQL statement using a prepared statement or parameterized query.
• Bind the array values to the question marks as parameters.

Example:

• Array: $galleries = array(1,2,5)

SQL Query:

SELECT *
FROM galleries
WHERE id IN (:id1, :id2, :id3)

• :id1, :id2, :id3 are named parameters.

Step 4: Execute the Query

• Execute the prepared statement with the array values bound as parameters.
