PHP Zip Archive - open or extractTo is not working

Question

I'm completely at a loss for explaining why this isn't working. HELP!

$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);

if ($res === 'TRUE') {
    $unzip_success= $zip->extractTo('/temp/', "inscriptions.txt")

    $zip->close();
}

• the target dir "temp" is "0777" permissions
• the code obtained from $res is "11" and not "TRUE" as required by the documentation on PHP.net
• note: must put the full url for $archive and the first argument of extractTo

Answer 1

if nothing works then check if your server is linux. if its linux you can run unzip command to unzip your file via php's system/exec function. ie

system("unzip archive.zip");

to extract specific file you can check man docs for unzip. many times due to server parameters zip library doesn't work as expected in that cases i switch back to linux commands.

Answer 2

The problem is that you are quoting TRUE , which is a keyword and should be left without single quotes. Plus, you could check if the file exists in the zip archive prior to its extraction with locateName :

$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);

if ($res === true && $zip->locateName('inscriptions.txt') !== false) {
    $unzip_success= $zip->extractTo('/tmp/', "inscriptions.txt");

    $zip->close();
}

Answer 3

ZipArcive::extractTo is case-sensitive. If file's name to be extracted do not meet zipped one exactly, the method returns false.

Answer 4

I faced the same problem, I have fixed this :) Use $_SERVER['DOCUMENT_ROOT'] for url. My code (codeigniter):

$this->load->library('unzip');
$file = $this->input->GET('file');
$this->unzip->extract($_SERVER['DOCUMENT_ROOT'].'/TRAS/application/uploads/' .    $file,$_SERVER['DOCUMENT_ROOT'].'/TRAS/application/views/templates/' . $file);

Answer 5

If $res is equal to 11, that means that ZipArchive can't open the specified file.

To test this:

$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);

if($res == ZipArchive::ER_OPEN){
    echo "Unable to open $archive\n";
}

Adding document root is what worked for me as well. here is my code

$zip = new ZipArchive;
        if ($zip->open($_SERVER['DOCUMENT_ROOT'].'/'.$folder.$file_path) === TRUE) {
            $zip->extractTo($_SERVER['DOCUMENT_ROOT'].'/$folder');
            $zip->close();
            echo 'ok';
        }

Answer 7

I meet same problem, but I can open the zip file, it returns true after open.

My issue is I got false after $zip->extractTo() .

I finally success after delete files named in CHINESE (NO-ENGILISH) in the zip file.

Answer 8

I had the same problem on Windows 10. The only solution I found was just to try extractTo twice, even though the open() was successful:

$zip = new ZipArchive;
if ($open === true) {
    $result = $zip->extractTo($destination);
    if ($result === false) {
        $result = $zip->extractTo($destination);
    }
    $zip->close();
}

The fact that the second extractTo() works (with no intervening action) would seem to indicate that there's nothing wrong with the archive or the destination directory.
