Need help "extracting" text from a file...

[hstraf]

I'm trying to extract a certain range of text from a file, edit it, and then put it back. I hope someone can help me.

Let's say I have a file like this:[quote]
asdjfasdlfads
fasd
fasd
ffasdf <!-- #startoftext comment here-->This part here is what I want to get
and here
and more
and also here<!-- #endoftext -->asldjfalsdjfalskdjfasd
fasd
asd
fasd
f[/quote
So everything between the two html comments is what I need to "extract".

Does anyone know how to do this? Any code samples I can use to learn how to do it?

My end goal is to extrac the text between the comments, put it into a textbox, edit it, and then save it back to the file after editing.

Thanks!

You could try rigging it like this, just create unique "start" and "end" markers for each segment you'd want to extract...

<?
// Load full text into variable
$text = "
whatever whatever whatever
<!--#start_marker-->
This part here is what I want to get
and here
and more
and also here
<!--#end_marker-->
whatever whatever whatever
";

// strip out unwanted text
$text = split('<!--#start_marker-->',$text);
$text = split('<!--#end_marker-->',$text[1]);
$text = $text[0];

// echo just the part you want
echo $text;
?>
