Are there any potential drawbacks or limitations to using output buffering in PHP?

One potential drawback of using output buffering in PHP is that it can increase memory usage, especially if large amounts of data are being stored in the buffer. This can lead to performance issues on servers with limited resources. To mitigate this, it is important to use output buffering judiciously and only when necessary.

// Example of using output buffering in PHP
ob_start();

// Output some content
echo "Hello, world!";

// Get the contents of the buffer and clean it
$output = ob_get_clean();

// Output the buffered content
echo $output;
