Here's my error "Error : PCLZIP_ERR_READ_OPEN_FAIL (-2) : Unable to open archive 'Transparentia.zip' in wb mode"
Using this code:
//download library from http://www.phpconcept.net/pclzip/index.en.php#download
//zip file name
$new_zip= new PclZip('backup.zip');
//backup theimages folder
$file_list = $new_zip->create('images/');
if ($file_list == 0)
die("Error : ".$new_zip->errorInfo(true));
echo "Successfully created zip file";
which I found at a site.
I double checked, it's loading the pclzip.lib.php file, so that's not the problem.
talence: It needs to be zip, so that it's user friendly.
