I'm trying to open a zip file in mode OVERWRITE. I always end up getting error 
code 1,

Test script:
$this->archiveName = TEMP_DIR . '/archive_' . $this->tid . '_' . date('Ymd') . '.zip';

$errorCode = $this->zipArchive->open($this->archiveName, ZipArchive::CREATE);
if ((integer)$errorCode > 0)
    throw new RuntimeException('Unable to open archive ' . $this->archiveName . ' (Error: ' . $errorCode . ')');

if (empty($this->files))
    throw new RuntimeException('No files available to be added to the archive.');

foreach ($this->files as $filename => $filepath)
    $this->zipArchive->addFile($filepath, $filename);

if (!$this->zipArchive->close())
    throw new RuntimeException('An error occured while trying to write the archive.');

return $this->archiveName;

can you create a self contained script? Use addFromString instead and drop 
everything not needed like exceptions and co, easier/faster for me to debug then.

Here is a little self contained script producing the same error:

$zip = new ZipArchive();

$archiveName = '';
$error = $zip->open($archiveName, ZipArchive::OVERWRITE);
echo $error . PHP_EOL; // outputs '1'

$zip->addFromString('text.txt', 'Lorem Ipsum');

After some more investigation along with an colleague I've found the source of 
issue: I was trying to create the archive inside an directory which is symlinked 
to another directory. After adding realpath() to the archivename, the file could 
be successfully opened and stored.

I'm not sure if the error message was helpful at all and could be changed in the

hm, it supports symlink smoothly. Let me test again.

I have a same issue with PHP7.0 on ubuntu 15.10 but I dont have symlinks.

In OVERWRITE mode I get error code 1. But using mode CREATE zip file is successful created.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

From documentation:
 ZipArchive::CREATE (integer):    Create the archive if it does not exist. 
 ZipArchive::OVERWRITE (integer): If archive exists, ignore its current contents.

So I only see expected behavior
