How to trim this line of code

This php code displays a name from the database but sometimes the names are too long. How do i trim the name to only display 20 characters?

$itemhtml = str_replace( '{name}', $item->link_name, $itemhtml );

 

$itemhtml = str_replace( '{name}', $item->link_name, $itemhtml ); 

// Now we shorten $itemhtml to 20 characters
$itemhtml = substr("$itemhtml", 0, 20);

PHP:

 

Hi..,

Substr() function in php will give you a solution for your problem.

Thanks

 

I bet it'll run as one liner as well

 

$itemhtml = substr("$itemhtml", 0, 20);
