A problem with ZipArchive

Hi,

So far, last Friday, every file file I try and open and unzip with
the ZipArchive class has failed.

I have just used ZipArchive to create a zip file and then
attempt to unzip it.

Even this has failed.

Does this means that my server ZipArchive class is somehow corrupted ?

Should I reinstall that php class ( I think it is via PECL )

Or is there another reason ?

here is my script for creating the zip file
and then unzipping it.

( Because I am trying to trap every error it is longer than usual )


$new_zip = $file_dir.'aaa_new.zip';

if (!class_exists('ZipArchive')) {
write_log("Class ZipArchive not found\r\n");
exit;
}
else {
write_log("Class ZipArchive OK\r\n");
$zip = new ZipArchive;
}

$res = $zip->open($new_zip, ZipArchive::CREATE);
if ($res === TRUE) {
$zip->addFromString('data1.txt', 'file content goes here');
$fin = $zip->close();
if ($fin === TRUE) {
write_log("Created zip file: $new_zip\r\n");
}
else {
write_log("Error on close: $fin \r\n");
exit;
}
}
else {
write_log("Could NOT Create zip file $res\r\n");
}


if (!$new_zip) {
write_log("Could not find $new_zip\r\n");
exit;
}
else {
write_log("Found: $new_zip\r\n");
}

$zip = new ZipArchive;

$res = $zip->open($new_zip);
if ($res === TRUE) {
write_log("File $new_zip OPENED\r\n");
}
else {
write_log("Could not open $new_zip\r\n Error # $res\r\n");
exit;
}

if ($zip->extractTo($file_dir) === TRUE) {
write_log("Extracted: $new_zip\r\n");
$zip->close();
}
else {
write_log("Extraction error\r\n");
}

$zipSS = $zip->getStatusString();
write_log("StatusString: $zipSS\r\n");


$fin = $zip->close();
if ($fin === TRUE) {
write_log("Unzipped file to: $file_dir\r\n");
}
else {
write_log("Error on close: $fin \r\n");
exit;
}
exit;


And YES the file "aaa_new.zip" does get created on
my server.

This is the log output:

Class ZipArchive OK
Created zip file: /home/gudfrt/public_html/stres/aaa_new.zip
Found: /home/gudfrt/public_html/stres/aaa_new.zip
File /home/gudfrt/public_html/stres/aaa_new.zip OPENED
Extracted: /home/gudfrt/public_html/stres/aaa_new.zip
StatusString:
Error on close:


Any ideas ?
