$zip = new Ziparchive (); First instantiate this class
if ($zip->open (' F:\test.zip ', ziparchive::overwrite=== TRUE)) {
$zip->addfile ("1439879545373869963.jpg");
Zip_close (); Shut down
echo ' OK ';
} else {
Echo ' failed ';
}

This is a very simple compression code, but this error will occur I use the Wamp integration package environment, PHP is 5.5 version, is not required to open PHP_ Zip.dll extension, again by the output can be output OK, that is, the Ziparchive class is successfully created, so should not be an extension of the problem, but Ziparchi is the method has been error, looking for a long time also do not know why, seek answers
