one way is to use html tags when you input your information in the textbox. Those tags will be stored as text in your db and understood by the browser as you display it back on the screen.
Either you end each line with a BR tag or you use the PRE tags around the whole textbox.
Another way is to use php and split up the string with the split function
You can then address each word and with php code echo it out where you want it.
