Are there any PHP functions or methods that can help with limiting text length in output?

When outputting text in PHP, it may be necessary to limit the length of the text to a certain number of characters to prevent overflow or maintain a clean layout. One way to achieve this is by using the `substr()` function, which allows you to extract a portion of a string based on a specified start and length. 

// Example code to limit text length in output
$text = "This is a long text that needs to be limited in length for display purposes.";
$limited_text = (strlen($text) > 20) ? substr($text, 0, 20) . '...' : $text;

echo $limited_text;
