Hello everyone,
Basically I just found about about zlib and php. For a long while I
have been searching for a provider that allows zip compression through
php scripts and now I have this instead.
I have been playing around with it for a while, but I cannot seem to
gz multiple files at the same time, as in place them in the same
archive.
My goal is to be able to run a php script to compress and backup
folders, and I understand I will need to use recursion to retrieve all
the files but I would like to be able to append files to an archive
before I get into the more advanced part of the script.
Here is some sample code I have modified. I believe I originally found
it on http://php.net/zlib
This script takes a parameter I set to "index.php" and firsts adds
that to the gz file.
Then I hardcoded a second file for testing purposes called
"mainLeft.php". I want to open the index.php.gz and see both index.php
and mainLeft.php, however I only see index.php. However, index.php is
actually contains the contents of mainLeft.php.
Here is the script:
<?php
function compress($srcFileName)
{
$dstFileName = $srcFileName . ".gz";
// getting file content
$fp = fopen( $srcFileName, "r" );
$data = fread ( $fp, filesize( $srcFileName ) );
fclose( $fp );
// writing compressed file
$zp = gzopen( $dstFileName, "w9" );
gzwrite( $zp, $data );
$srcFileName = "mainLeft.php";
// getting file content
$fp = fopen( $srcFileName, "r" );
$data = fread ( $fp, filesize( $srcFileName ) );
fclose( $fp );
// writing compressed file
$zp = gzopen( $dstFileName, "w9" );
gzwrite( $zp, $data );
gzclose( $zp );
}
compress("index.php");
?>
