Programming Forums - PHP to ZIP a directory.

I need to zip all the files in a directory (not including the folder). i tried to use an example on www.php.net/sip to help me but i get a parse error. heres the whole code i have. The SQL statments insert it into a PHP nuke evo database. it already puts the files in the downloads section but i want it to include the ZIP file (as if to download all files).

<?php

$server = 'cali';

$etmain_cid = '3';

$etpub_cid = '';

$jaymod_cid = '4';

$etpro_cid = '';







$date = date('Y-m-d H-i-s');

$etmain = './etmain';

$etpub = './etpub';

$jaymod = './jaymod';



mysql_connect('localhost','***','***');





////////////////////////////////////

////////////Etmain/////////////////

//////////////////////////////////





$zip = new ZipArchive();

$filename = "./allfiles-$date";



while($file1 = readdir($directory1)) {







                if($file1 != "." && $file1 != ".." && $file1 != "index.html"){

                $stat1 = stat("$etmain/$file1");

                $filesize1 = $stat[7];

                echo '<tr><td>' . $file1 . '</td><td>' . $filesize1 . '</td></tr>';







if ($zip->open($filename1, ZIPARCHIVE::CREATE)!==TRUE) {

** exit("cannot open <$filename>\n");

}



$zip->addFile($etmain . "/$file1");

echo "numfiles: " . $zip->numFiles . "\n";

echo "status:" . $zip->status . "\n";

$zip->close();







}

}









mysql_query("DELETE FROM c1hess_phpnuke.nuke_downloads_downloads WHERE cid='$etmain_cid'");

if($directory = opendir($etmain)){

echo '<table border="1">Etmain additions:';

while($file = readdir($directory)) {



                if($file != "." && $file != ".." && $file != "index.html"){

                $stat = stat("$etmain/$file");

                $filesize = $stat[7];

                echo '<tr><td>' . $file . '</td><td>' . $filesize . '</td></tr>';





mysql_query("INSERT INTO c1hess_phpnuke.nuke_downloads_downloads (`cid`,`title`,`url`,`description`,`date`,`submitter`,`filesize`,`sub_ip`,`active`) VALUES ('$etmain_cid','$file','http://www.1hess.com/modsandmaps/$server/etmain/$file','Game File for [HESS] $server download to etmain.','$date','Piercy\'s directory bot','$filesize','$ip','1')");



}

}

echo '</table>';











closedir($directory);

}

?>

the parse error i get is:
Parse error: parse error, expecting `'('' in /Users/mike/sites/untitled folder/index.php on line 37

line 37 is:

if ($zip->open($filename1, ZIPARCHIVE::CREATE)!==TRUE) {

usually parse errors are easy to solve but i dont really know what im doing with the zip code.

Thanks in advance,
Piercy
