preg_split problem

[Peter]

L.S.

I am trying to cut a string into substrings. The string at hand looks
something like this:

$data='one|two| three|four\nfiv e|six|seven|eig ht'; //observe the chr(10) in
the middle

I would like to have this split two times. Once to give me the two
'sentences' 'one|two|three| four' and 'five|six|seven |eight'. Then, each of
these sentences would be split into their repective words. Initially I
thought it would be simple:

$sentence=preg_ split("\n",$dat a); //should give me an array $sentence
$word=preg_spli t("|",$senten ce[0]); //should give me an array $word

Unfortunately this doesn't work and now I am caught up in a new world of
'regular expression functions' that doesn't seem to make any sense. Can you
please help me to get this split function to do what I need?

Thanks for your reply, Peter.

YES!!! That appears to do the trick. Thank you.

As pointed out elsewhere, it is better to use explode.

However, if you are doing things like this with pcre, you have to bear in mind
that if your expressions contain newlines, you have to use a multiline modifier.
Have a read and a play with it (read the manual stuff on modifiers)
