How can PHP developers ensure that only specific output is displayed while running a script, like in the case of the Teamspeak Verification Skript?

To ensure that only specific output is displayed while running a script, PHP developers can use output buffering to capture the output and then selectively display only the desired content. This can be achieved by starting output buffering before any output is generated and then using functions like ob_get_contents() to retrieve the buffered output for manipulation.

<?php

ob_start();

// Code that generates output

$output = ob_get_contents();
ob_end_clean();

// Display only specific output
echo "Specific Output: " . $output;

?>
