How to Construct an SQL WHERE Clause Using a PHP Array?

Constructing an SQL Query with Array-based WHERE Clause

In a scenario where you wish to filter a database table based on an array of values, you can employ a technique that involves incorporating the values into a WHERE clause using the IN operator.

To achieve this, a dynamic SQL query can be generated using a PHP script as follows:

$galleries = array(1, 2, 5);

$query = "SELECT * FROM galleries WHERE id IN (" . implode(',', $galleries) . ")";

In this example, the $galleries array contains the ids 1, 2, and 5. The implode function is utilized to concatenate these values into a comma-separated string which is then inserted into the WHERE clause.

This query will effectively retrieve all rows from the galleries table where the id column matches any of the values in the $galleries array, namely 1, 2, or 5.
