Description: Create an object of the ZipArchive class and open a given zip file using $zip->open() method. If it returns TRUE then extract the file to the specified path with extractTo() method by passing path address as an argument in it. Example 2: This example unzip the specific file from the folder.
Try this code :". zip"; $file = fopen($destination, "w+"); fputs($file, $data); fclose($file);
I can only assume your code came from a tutorial somewhere online? In that case, good job trying to figure it out by yourself. On the other hand, the fact that this code could actually be published online somewhere as the correct way to unzip a file is a bit frightening.
PHP has built-in extensions for dealing with compressed files. There should be no need to use system calls for this. ZipArchivedocs is one option.
$zip = new ZipArchive;
$res = $zip->open('file.zip');
if ($res === TRUE) {
$zip->extractTo('/myzips/extract_path/');
$zip->close();
echo 'woot!';
} else {
echo 'doh!';
}
Also, as others have commented, $HTTP_GET_VARS has been deprecated since version 4.1 ... which was a reeeeeally long time ago. Don't use it. Use the $_GET superglobal instead.
Finally, be very careful about accepting whatever input is passed to a script via a $_GET variable.
UPDATE
As per your comment, the best way to extract the zip file into the same directory in which it resides is to determine the hard path to the file and extract it specifically to that location. So, you could do:
// assuming file.zip is in the same directory as the executing script.
$file = 'file.zip';
// get the absolute path to $file
$path = pathinfo(realpath($file), PATHINFO_DIRNAME);
$zip = new ZipArchive;
$res = $zip->open($file);
if ($res === TRUE) {
// extract it to the path we determined above
$zip->extractTo($path);
$zip->close();
echo "WOOT! $file extracted to $path";
} else {
echo "Doh! I couldn't open $file";
}
Please, don't do it like that (passing GET var to be a part of a system call). Use ZipArchive instead.
So, your code should look like:
$zipArchive = new ZipArchive();
$result = $zipArchive->open($_GET["master"]);
if ($result === TRUE) {
$zipArchive ->extractTo("my_dir");
$zipArchive ->close();
// Do something else on success
} else {
// Do something on error
}
And to answer your question, your error is 'something $var something else' should be "something $var something else" (in double quotes).
Using getcwd() to extract in the same directory
<?php
$unzip = new ZipArchive;
$out = $unzip->open('wordpress.zip');
if ($out === TRUE) {
$unzip->extractTo(getcwd());
$unzip->close();
echo 'File unzipped';
} else {
echo 'Error';
}
?>
I updated answer of @rdlowrey to a cleaner and better code, This will unzip a file into current directory using __DIR__.
<?php
// config
// -------------------------------
// only file name + .zip
$zip_filename = "YOURFILENAME.zip";
?>

$zip = new ZipArchive;
$res = $zip->open(__DIR__ . '/' .$zip_filename);
if ($res === TRUE) {
$zip->extractTo(__DIR__);
$zip->close();

}

End Script.

Simply try this yourDestinationDir is the destination to extract to or remove -d yourDestinationDir to extract to root dir.
$master = 'someDir/zipFileName';
$data = system('unzip -d yourDestinationDir '.$master.'.zip');
PHP has its own inbuilt class that can be used to unzip or extracts contents from a zip file. The class is ZipArchive. Below is the simple and basic PHP code that will extract a zip file and place it in a specific directory:
<?php
$zip_obj = new ZipArchive;
$zip_obj->open('dummy.zip');
$zip_obj->extractTo('directory_name/sub_dir');
?>
If you want some advance features then below is the improved code that will check if the zip file exists or not:
<?php
$zip_obj = new ZipArchive;
if ($zip_obj->open('dummy.zip') === TRUE) {
$zip_obj->extractTo('directory/sub_dir');
echo "Zip exists and successfully extracted";
}
else {
echo "This zip file does not exists";
}
?>
