Extract a zip file online. Cleans up afterwards (deletes zip and this script). Can be used as a fast and simple deploy option, without using too much bandwidth

index.php

<?php

$files = glob("*.zip");

if (count($files) == 0) {
    echo "no zip files found";
    exit;
}
else if (count($files) > 1) {
    echo "multiple zip files found";
    exit;
}

$zip = new ZipArchive;
$zip->open($files [0]);
$zip->extractTo('./');
$zip->close();

unlink("index.php");
unlink($files[0]);

?>
