creating gzip file with php

[Anon]

Is there a way I can take a text file and gzip it using PHP?
I have had a look in the manual and all I can see is gzip reading functions;
nothing to create a gzip file.

Looks like you have been skipping a few pages.. 🙂

Ah.. I had a feeling it would be you who replied.
That sounds like what I'm looking for, although the note suggests I might want something a little different if I want a proper gzip:
This is not the same as gzip compression, which includes some header data. See gzencode() for gzip compression.

Okay, I have a related question:
I'm pulling database records out using php - and writing them to a text file I want people to download... the file is being written to a Linux server, but the carriage returns are written with the infamous ^M - how can I prevent this?

Hmm I wonder where the ^M comes from.
Is it stored in the database? (in that case you'd better fix your database instead of fixing the output)

Not in the database records.
I'm making a concatenated string and sending each string out to a file using

$fp = fopen("/home/httpd/html/web/ssa/sql/output/local_info.txt", "w");

and then

$intro="Hello world\n"; (for example, although my string is a larger)

then;

fwrite( $fp, $intro);
fclose( $fp );

Looking at this again, it must be the \n that's causing it - but what can I use instead?

sorry - it should be "\n" - I was expecting this site to strip one slash out.
