Para subir un archivo zip y descomprimirlo directamente en el servidor podemos utilizar el siguiente script:
<?php
function recursive_dir($dir) {
foreach(scandir($dir) as $file) {
if ('.' === $file || '..' === $file) continue;
if (is_dir("$dir/$file")) recursive_dir("$dir/$file");
else unlink("$dir/$file");
}
rmdir($dir);
}
if($_FILES["zip_file"]["name"]) {
$filename = $_FILES["zip_file"]["name"];
$source = $_FILES["zip_file"]["tmp_name"];
$type = $_FILES["zip_file"]["type"];
$name = explode(".", $filename);
$accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/x-compressed');
foreach($accepted_types as $mime_type) {
if($mime_type == $type) {
$okay = true;
break;
}
}
$continue = strtolower($name[1]) == 'zip' ? true : false;
if(!$continue) {
$myMsg = "Please upload a valid .zip file.";
}
/* PHP current path */
$path = dirname(__FILE__).'/';
$filenoext = basename ($filename, '.zip');
$filenoext = basename ($filenoext, '.ZIP');
$myDir = $path . $filenoext; // target directory
$myFile = $path . $filename; // target zip file
if (is_dir($myDir)) recursive_dir ( $myDir);
mkdir($myDir, 0777);
/* here it is really happening */
if(move_uploaded_file($source, $myFile)) {
$zip = new ZipArchive();
$x = $zip->open($myFile); // open the zip file to extract
if ($x === true) {
$zip->extractTo($myDir); // place in the directory with same name
$zip->close();
unlink($myFile);
}
$myMsg = "Your .zip file uploaded and unziped.";
} else {
$myMsg = "There was a problem with the upload.";
}
}
?>

Si solo queremos descomprimir un archivo zip desde el servidor y no podemos subirlo con el anterior script por algun tipo de limitación del tamaño de la subida podríamos usar el siguiente script que descomprime:
$myFile = 'newnew.zip'; // target zip file
$folderSave = "prueba"; // hauria d'exisitir
$zip = new ZipArchive();
$x = $zip->open($myFile); // open the zip file to extract
if ($x === true) {
$zip->extractTo("desc"); // place in the directory with same name
$zip->close();
//unlink($myFile);
}
$myMsg = "Your .zip file unziped.";
