How can the performance of SQL queries in PHP be optimized to handle a large number of data entries more efficiently?

To optimize the performance of SQL queries in PHP for handling a large number of data entries more efficiently, you can use prepared statements to reduce the overhead of repeatedly parsing and compiling the same query. Prepared statements also help prevent SQL injection attacks. Additionally, you can consider indexing the columns that are frequently used in your queries to speed up the data retrieval process. 

// Example of using prepared statements in PHP to optimize SQL queries
$stmt = $pdo->prepare("SELECT * FROM table WHERE column = :value");
$stmt->bindParam(':value', $value);
$stmt->execute();
$results = $stmt->fetchAll();
