My title one worked, but I like your idea. I started to write that you
were all flip-flopped on your title example, until I realized you were
using preg_replace instead of preg_match.
quoting Mr. Spock:
An ancestor of mine maintained, that if you eliminate the impossible,
whatever remains, however improbable, must be the truth.
Ditto for body.
now I have
// strip everything above and including
$body = preg_replace("/.*/iU",'',$file_text);
// strip everything after and including
$body = preg_replace("/<\/body>.*/i",'',$body);
Works lik a charm!
Thanks :)

Since you're looking for certain tags, it stands to reason that you're
primarily interested in characters after "<" characters. So this might
be faster:
$chunks = split( "<", $file_text );
for( $i = 0; $i < count( $chunks ); $i++ )
{
if( 0 === strpos( $chunks[$i], "title" ) )
{
# Title starts after the next ">", so get it.
# If you're careful, you can modify $i here
# as you gather up the title.
}
if( 0 == strpos( $chunks[$i], "body" ) )
{
# Body starts after the next ">"
# Modify $i, but be vewwy caweful.
}
}
The de-commenting is left to the reader.

What governs the number of characters that ereg can process?
I looked at the phpinfo from both servers but didn't find any clues...
Thanks for the help :)
FYI sample code:
prepend--
ob_start();

Isnt ereg meant to be slower than preg anyway ?

[PHP] overloaded, overworked ereg statement?
This script worked on one server, but started choking after I moved it
to a new server.
Summary: I use the php_auto_prepend script to start output buffering,
then use the php_auto_append script to extract the content between the
title tags and between the body tags. When the size of the content
between the body tags reaches around 11,500 characters, the ereg
function stops working correctly.
What governs the number of characters that ereg can process?
