What is the potential issue with sending multiple database queries recursively in PHP?

The potential issue with sending multiple database queries recursively in PHP is that it can lead to performance degradation and potential server overload due to the increased number of connections and queries being executed. To solve this issue, it is recommended to optimize the queries, use caching mechanisms, batch queries where possible, and limit the depth of recursion to prevent excessive database calls. 

// Example of limiting recursion depth in PHP
function recursiveQuery($depth) {
    if ($depth > 3) {
        return; // Limit recursion depth to 3
    }

    // Perform database query
    $result = mysqli_query($connection, "SELECT * FROM table");

    // Process the result

    // Recursively call the function
    recursiveQuery($depth + 1);
}

// Initial call to the recursive function
recursiveQuery(1);
