How can the implode function be used effectively in PHP for SQL queries?

When constructing SQL queries in PHP, it is common to need to concatenate an array of values into a comma-separated list for use in an IN clause. The implode function in PHP can be used effectively for this purpose by joining the array elements with a comma. This can help simplify the query building process and make the code more readable. 

// Example of using implode for SQL queries
$ids = [1, 2, 3, 4, 5];
$idsString = implode(',', $ids);

$sql = "SELECT * FROM table WHERE id IN ($idsString)";
