Re: retrieving first paragraph

[Lisi <lists@shemeshdirectory.co.il>]

I'm still getting the entire text when I echo $paragraphs[0], and 
$paragraphs[1] is empty (I thought the array was supposed to have the whole 
text, and then the individual selected parts). I tried with both \n, which 
was balnk, and \n'n, which returned the entire text.

Any ideas why?

Thanks,

-Lisi
