[PHP] replacing a carriage return with an html break

[nate]

Hi all,

I am filling out a form <text area>, and submitting it to the next page which just 
prints what I submitted, but it doesnt print any returns, i used when i filled out the 
previous <text area>

I found on php.net there is a ereg_replace funtion and a trim function but I am unsure 
if either one will work and im not sure how to use them.

Thanks,
nate
