Chars with no space

Ok having difficulty here!!!

I have a table, with a table within a table.
The tables are set up with html and php.

My problem is that when characters are entered into the textbox, or textarea I should say, and then the screen is viewed after the input is entered into the database, the tables alter in width and size to adjust to the characters, rather then breaking them apart.

Is there some quick code I can use to break apart a string of characters that do not have an break or space entered in order to prevent the browser from getting a scroll bar and adjusting my tables to suit the characters??

I tried wrap it didn't work. I tried no scrollbar, it didn't work.

Any other ideas?

you would want to check the input before it's entered into the database.. for example:

ok so curiously why 160?
I'm working with it and I am getting an error that says:
wordwrap() expects parameter 2 to be long, string given in "file" on line "line".

I got it working!!!
Thanks so much!
I'd never heard of the wordwrap function before.

Ok So how can I reverse it?
So that on the form where thy update, and the information prints out with the <br />
It doesn't actually print out with the <br />?

you might want to do this:

str_replace("<br />", "/n", $input);
