What are some best practices for implementing random time intervals in PHP for displaying or not displaying content?

To implement random time intervals in PHP for displaying or not displaying content, you can use the `rand()` function to generate a random number representing the time interval. You can then use this random number to determine whether to display the content or not. By setting a threshold value, you can control the probability of displaying the content at any given time.

// Generate a random number between 1 and 10
$randomNumber = rand(1, 10);

// Set a threshold value for displaying content
$threshold = 5;

// Check if the random number is below the threshold to display content
if ($randomNumber <= $threshold) {
    echo "Display content";
} else {
    echo "Do not display content";
}
