What tools can be recommended for analyzing database performance in PHP applications?

Analyzing database performance in PHP applications can be crucial for identifying bottlenecks and optimizing queries. One recommended tool for this task is the MySQL EXPLAIN statement, which provides insights into how MySQL executes a query and helps optimize it. Another helpful tool is the MySQL Slow Query Log, which logs queries that take longer than a specified time to execute, allowing you to identify and optimize slow queries. 

// Example of using MySQL EXPLAIN to analyze query performance
$query = "SELECT * FROM users WHERE id = 1";
$explain = "EXPLAIN " . $query;
$result = mysqli_query($connection, $explain);

// Output the EXPLAIN results
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['id'] . " | " . $row['select_type'] . " | " . $row['table'] . " | " . $row['type'] . " | " . $row['rows'] . " | " . $row['Extra'] . "<br>";
}
