PHP Create Zip File Function

To use these functions, make sure that zlib have been loaded by php runtime. Use this trick to find zlib has been loaded by php, create new file php (Ex:phpinfo.php), fill the file with this(without quote): “<?php phpinfo();?>“. Put it on the web folder then open with mozilla fire fox.

If zlib have been loaded by php, Let’ start creating the Zip file.
* Create files 1.txt, 2.txt, 3.txt, 4.txt And Create makezip.php (in the same directory with file 1.txt).
Fill the makezip.php with this:

<?php
$zip = new ZipArchive();
$filename = "test.zip";
if ($zip-&gt;open($filename, ZIPARCHIVE::CREATE)!==TRUE) { exit("cannot open"); }
$zip-&gt;addFromString("1.txt", "time create zip ".time()." #1 This is a test string added as 1.txt.\n");
$zip-&gt;addFromString("2.txt" . time(), "#2 This is a test string added as 2.txt.\n");
$zip-&gt;addFile($thisdir . "3.txt","4.txt");
// file 3.txt while be renamed to 4.txt 
echo "numfiles: " . $zip-&gt;numFiles . "<br />";
echo "status:" . $zip-&gt;status . "<br />";
echo "Directory: ".getcwd()."<br />Filename: $filename"; $zip-&gt;close();
?>

Upload files to your web directory, then open up makezip.php with your web browser. Look at your web directory, you will see the test.zip. :D
