Help with fixing a simple syntax error

[Fitz]

Hi,

 

I've coded the following script which is meant to dump files from my server into a created .zip file, then allow the user to download them. The following script works successfully on one server I have, but simply displays this error on another server where it is uploaded:

 

Parse error: syntax error, unexpected ')', expecting '(' in ************************ on line 13

 

For reference, line 13 is this:

$zipobject->open("images.zip", ZipArchive::OVERWRITE);

 

Here is the complete code:

<?php
//Defines header
header("Content-type: application/zip"); 
header('Content-Disposition: attachment; filename="Screen_Images.zip"');

//Creates "images.zip" file for writing
$ourFileName = "images.zip";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);

//Creates a new ZipArchive from the previously created "images.zip" file
$zipobject = new ZipArchive();
$zipobject->open("images.zip", ZipArchive::OVERWRITE);

//Defines some variables
$set_array = array('maintenance','operations');
$main_array = array('main1','main2','main3','main4','main5');
$images_array = array('image1.bmp','image2.bmp','image3.bmp','image4.bmp','image5.bmp','image6.bmp','image7.bmp','image8.bmp','image9.bmp','image10.bmp');

//Adds multiple files to "images.zip" if they exist
for ($x = 0; $x < sizeof($set_array); $x++) {
for ($y = 0; $y < sizeof($main_array); $y++) {
for ($z = 0; $z < sizeof($images_array); $z++) {
$filename2[$x][$y][$z] = $_GET['account']."/".$set_array[$x]."/".$main_array[$y]."/".$images_array[$z];
if (file_exists($filename2[$x][$y][$z])) {
$zipobject->addFile($filename2[$x][$y][$z]);
}
}
}
}
$zipobject->addFile("screen_creator.exe", $_GET['account']."/screen_creator.exe");
$zipobject->addFile($_GET['account']."/Convert_To_Scr.bat");

//Closes the Zip file and echos it, which displays a download box for the user to download the packaged "images.zip" file
$zipobject->close();
echo file_get_contents("images.zip");

//Deletes the "images.zip" file from the server
unlink($ourFileName);
?>

 

Again, it works perfectly on one server, but displays the above syntax error on another. I need it to work on both servers, but I can't figure out the meaning of the error as it appears that the ')' should be there.

 

Help with this would be greatly appreciated, thanks!

may be the zip extension is not enabled on ur new server. please check. u can see it in phpinfo() if u dont have access to php.ini

Is ZipArchive::OVERWRITE a static property or a method? If the latter, then it should be ZipArchive::OVERWRITE()

Thanks for the replies!

 

I actually found out that it gets rid of the error if I simply leave out the OVERWRITE function and make line 13:

$zipobject->open("images.zip");

 

According to the PHP manual (http://us.php.net/manual/en/function.ziparchive-open.php), I was in fact using the OVERWRITE property correctly, however discovered that this property wasn't really even needed in the script since because it already create a new zip folder every time with fopen, there's no need to overwrite anything.

 

But, I'm afraid I have a new problem. Everything is still working perfectly on my first server, and the second server now is able to download the .zip file without errors due to the above changes I made.

 

However, whenever I try to open the .zip file downloaded from the second server, I get this error:

The Compressed (zipped) is Invalid or Corrupted.

After doing a quick check, I found that my second server is on PHP Version 4.4.9 - however, apparently the "ZipArchive::addFile" command I am using requires PHP 5.2.0.

 

So I suppose my new question is - is there any command similar to "ZipArchive::addFile" (http://us.php.net/manual/en/function.ziparchive-addfile.php) that will work in PHP 4.4.9? Or, if not - is there any way that I'm able to allow a user to download a .zip file which contains multiple files from the server, in PHP 4.4.9?

 

Thanks in advance!
