Singleing out a specific ammount of data

[gspree]

Hi.

In a script I've written, I use strstr() to locate a certain point in a HUGE gzip file. The problem is that since the file is so huge, strstr() returns a huge ammount of data as it will return everything between the position of what I search for and the end of the file.
And because of this, my script runs incredibly slowly. Is there another function that does the same as strstr() but can also take a value for where to stop the returning of data? Like return everything between "Point A" and "Point B" in the below file segment:

blablablabla
blablaaablabla
Point A blablabla
blabla bla
bla
bla Point B
bla bla bla
blabla

Because with strstr(), I would get everything from Point A to the end of the file!

Thanks for any help.

Hmm... You should use something like:

$pointa = strpos($text, "Point A");
$pointb = strpos($text, "Point B", $pointb);

$returndata = substr($text, $pointa, $pointb-$pointa);

It's fast and simple. If you wonder why the $pointb = .. line is different from the first line, it's just because I want to search for Point B after Point A. It will be faster that way.

Thanks alot!

This seems to be just what I wanted.

Actually, don't you mean to use $pointa as the offset for your second call to strpos?

Of course. Just a typo.

Thanks for finding it!
