How can tools like FireBug be utilized to troubleshoot slow data loading times in PHP applications?

To troubleshoot slow data loading times in PHP applications using tools like FireBug, you can use the Network tab to analyze the network requests and identify any bottlenecks. Look for slow loading resources or large file sizes that may be causing the slowdown. You can also check for inefficient database queries or code that may be causing delays in processing data. 

// Example code snippet to optimize database query for faster data loading

// Original query
$query = "SELECT * FROM users WHERE status = 'active' ORDER BY created_at DESC LIMIT 10";
$result = mysqli_query($connection, $query);

// Optimized query with indexing
$query = "SELECT * FROM users WHERE status = 'active' ORDER BY created_at DESC LIMIT 10";
$result = mysqli_query($connection, $query);

// Add index to 'status' and 'created_at' columns for faster retrieval
mysqli_query($connection, "CREATE INDEX status_index ON users (status)");
mysqli_query($connection, "CREATE INDEX created_at_index ON users (created_at)");
