Question How to unzip the *.bz2 file using php coding?


Hello everyone,
Below is my code to create *.bz2 file.

<?php

//Moving file to temporary directory for compression

move_uploaded_file($_FILES["file"]["tmp_name"],"c:/" . $_FILES["file"]["name"]);

$url="c:/".$_FILES["file"]["name"];

//File compression

$file_pointer = fopen($url, "r");

$file_read = fread($file_pointer, filesize($url));

fclose($file_pointer);

$temp= pathinfo($_FILES["file"]["name"]);

$filename = "c:/".$temp['filename'].".bz2";

$bz = bzopen($filename, "w");

bzwrite($bz, $file_read);

bzclose($bz);

unlink($url);

//File decompression

$bz = bzopen($filename,"r");

$str = bzread($bz);

bzclose($bz);

$file_pointer = fopen ($url,"w+");

fwrite($file_pointer,$str);

fclose($file_pointer);


echo "Compression Done";

?>

Anyone know, how to unzip the file ? I've tried the above code to unzip it but it creates only 1kb of file for any files. Any ideas?

Thank you,

Regards,
Vijay......

Read the documentation for bzread (http://www.php.net/manual/en/function.bzread.php):
Code:
length
    If not specified, bzread() will read 1024 (uncompressed) bytes at a time.
Length is limited to 8192 according to a comment on php.net, so you might want to use a loop to extract the file.
