Help with unzipping .gz files

[affordit]

Hello all

I have been trying to loop thru a dir. of .gz files and unzip them into the dir. that this script runs in, can not seem to get it can someone help? Here is what I have

$buffer_size = 4096; // read 4kb at a time
if ($handle = opendir('./gz')) {

    while ($in_file = readdir($handle)) {
if($in_file != "." && $in_file != ".." && $in_file != "index.php"){

$file = gzopen($in_name, 'rb');
$out_file = fopen($out_file_name, 'wb');


while(!gzeof($file)) {

    fwrite($out_file, gzread($file, $buffer_size));
}

fclose($out_file);
gzclose($file);

}
}		


    


closedir($handle);
}

Thank all

I changed to this and still get nothing

$buffer_size = 4096; // read 4kb at a time
if ($handle = opendir('./gz')) {

    while ($in_file = readdir($handle)) {
if($in_file != "." && $in_file != ".." && $in_file != "index.php"){
$out_file_name = str_replace('.gz', '', $in_file);
$file = gzopen($out_file_name, 'rb');
$out_file = fopen($out_file_name, 'wb');


while(!gzeof($file)) {

    fwrite($out_file, gzread($file, $buffer_size));


fclose($out_file);
gzclose($file);
}
}
}		


    


closedir($handle);
}

No one has any ideas?

You might want to try using gzfile to read the file into an array and then using file_put_contents to create the new file:

<?php
$files = glob('./gz/*.gz');
foreach ($files as $in_file) {
    $tmp = gzfile($in_file);
    file_put_contents(str_replace('.gz','',basename($in_file)),implode('',$tmp));
}
?>

 

Note: completely untested.

I just tried my code on my server and it worked fine. There was one .gz file in my gz directory and when the program completed the expanded file was in the directory where I ran the code.

 

You might want to put a debugging line in your code, something like:

<?php
$files = glob('./gz/*.gz');
foreach ($files as $in_file) {
    $tmp = gzfile($in_file);
    echo basename($in_file) . ' ==> ' . str_replace('.gz','',basename($in_file)) . "\n";
    file_put_contents(str_replace('.gz','',basename($in_file)),implode('',$tmp));
}
?>

 

to see if you're even getting the files.
