how to zip all ftp files using php - php

Question

I have files in a remote location that I grab through ftp, and I want to zip all files and directory into a zip using php.
I've used this, but it does not work. Does anyone know how to zip files?
The below code doesn't work at all.
<?php
ini_set('max_execution_time', 5000);
class xZip {
public function __construct() {}
private function _rglobRead($source, &$array = array()) {
if (!$source || trim($source) == "") {
$source = ".";
}
foreach ((array) glob($source . "/*/") as $key => $value) {
$this->_rglobRead(str_replace("//", "/", $value), $array);
}
foreach ((array) glob($source . "*.*") as $key => $value) {
$array[] = str_replace("//", "/", $value);
}
}
private function _zip($array, $part, $destination) {
$zip = new ZipArchive;
#mkdir($destination, 0777, true);
if ($zip->open(str_replace("//", "/", "{$destination}/partz{$part}.zip"), ZipArchive::CREATE)) {
foreach ((array) $array as $key => $value) {
$zip->addFile($value, str_replace(array("../", "./"), NULL, $value));
}
$zip->close();
}
}
public function zip($limit = 50000, $source = NULL, $destination = "./") {
if (!$destination || trim($destination) == "") {
$destination = "./";
}
$this->_rglobRead($source, $input);
$maxinput = count($input);
$splitinto = (($maxinput / $limit) > round($maxinput / $limit, 0)) ? round($maxinput / $limit, 0) + 1 : round($maxinput / $limit, 0);
for($i = 0; $i < $splitinto; $i ++) {
$this->_zip(array_slice($input, ($i * $limit), $limit, true), $i, $destination);
}
unset($input);
return;
}
public function unzip($source, $destination) {
#mkdir($destination, 0777, true);
foreach ((array) glob($source . "/*.zip") as $key => $value) {
$zip = new ZipArchive;
if ($zip->open(str_replace("//", "/", $value)) === true) {
$zip->extractTo($destination);
$zip->close();
}
}
}
public function __destruct() {}
}
$zip = new xZip;
$zip->zip(50000, "auto/", "c/");
//$zip->unzip("images_zip/", "images/");
?>

If you are on Linux and not limited by php's safe_mode (use phpinfo() to find out) then you could simply use exec() to run the zip command from a shell like:
Method 1:-
<?php
exec("zip -R public_html.zip /home/username/public_html",$output);
?>
Method 2:-
<?php
$archive = "xyz.zip";
$directory = $_SERVER['DOCUMENT_ROOT'];
exec( "zip -r $archive $directory");
?>
For Local systems you can use this code for zip the specific folders.
<?php
function Zip($source, $destination)
{
echo "called function";
if (!extension_loaded('zip') || !file_exists($source)) {
return false;
}
$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file)
{
$file = str_replace('\\', '/', $file);
// Ignore "." and ".." folders
if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
continue;
$file = realpath($file);
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
return $zip->close();
}
Zip('D:/tmp','D:/tmp/compressed.zip',true);
?>
Hope this helps.
