URL output Trim or Character Limit

HI, I recently added a function that displays the Social Media URLs as a URL instead of the word “Instagram”, “Twitter” etc.

This is the function I added:
‘
add_filter( ‘geodir_custom_field_website_name’, ‘geodir_change_website_field_display_name’, 10, 3 );
function geodir_change_website_field_display_name($name,$website,$post_id){
if($name==’Twitter’ || $name==’Instagram’ || $name==’Website’){return $website ; }
else{return $name;}
}
‘

The function is working great, but I’m running into the issue of the URL length being too long and running out of the display box.

Would there be a way to TRIM the $website variable output to remove the “http://www.”?

OR

impose a character limit to the entire URL display?

Thank you!
Timothy
