I've made sort of a forum with PHP/MySQL and almost everything is ok except for the fact that when a user enters a long line without spaces, it's viewed without line breaks and it causes to break the layout of the table the data is arranged with.
I've thought that I might use the function nl2br(), but I'm not sure how to do it (before entering data on the DB, or afterwards on the output), or if there's no need to do it because there's something else better, for instance some CSS property.
I have another little problem regarding this issue and I need your help again:
I finally opted for using wordwrap, and I assigned a limit of characters so that too long lines without spaces were cut.
But another issue comes up:
As the characters have different widths, 100 sequential m's on a line would be much longer than 100 i's. Thus, the limit of characters will always be either too short if there are many narrow characters with quite a long limit or too long if there are many wide characters with quite a short limit, showing either too short containing cells or overflown cells respectively.
