I have a PHP function to catch long URLs and trim them so they don’t break my site’s formatting. I have wordwrap catching sentences but I can’t stop text like this:

‘aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa’

How would I stop user input like that ?

The things I’ve tried work if there’s dashes present (and I’ve tried ­ too in some functions) but none affect the above. It’s for a forum and this is the last bit of user input I can’t stop breaking my site ! Thanks for your help in advance.

    wordwrap() will break up long words if you include TRUE as the fourth parameter:

    wordwrap( $very_long_string, 30, '<br />', TRUE );

    This will insert a break at or before 30 characters. TRUE is required to force a break in long words. If FALSE (the default) is used, the lines are broken only on spaces.
