Hello Everyone,
Thanks for providing such a nice script to create an archive using php.
I have used this code to create backups of my website.
The code is working perfectly fine but I have an issue i.e. when I run this script at very first, it creates an archive - that is good but if I run the script again it creates an archive which overrides the previous one and includes that old archive into new one.
I want to exclude .zip files from compression.
Can you please help me in this matter?
I want to create an archive which should not contain any archive or .zip file into it.
I will be waiting for kind and positive response.
Thanks & Regards,
Mayank

Just replace few line and this issue will solve, everytime it will create a new zip
$dest=time()."backup.zip";
zipData('screenshots', $dest);
echo 'Finished.';

Hi,
@prashantkumarabhishek
You are right, But make sure to do not keep backups in site root. Keep it in Hosting root.
Thank you.

Maybe include "exclude folder/file" option now ?

Add ignored list (Array) and directory separator compatibility

`function zipData($source, $destination, $ignores = []) {
if (extension_loaded('zip')) {
if (file_exists($source)) {
$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE)) {
if (is_dir($source)) {
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source, RecursiveDirectoryIterator::SKIP_DOTS), \RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {

					$ignored = false;

					foreach ($ignores as $ignore) {
						if(strpos($file, $ignore)){
							$ignored = true;
							break;
						}
					}

					if($ignored){
						continue;
					}

					if (is_dir($file)) {
						$zip->addEmptyDir(str_replace($source . DIRECTORY_SEPARATOR, '', $file . DIRECTORY_SEPARATOR));
					} else if (is_file($file)) {
						echo(str_replace($source . DIRECTORY_SEPARATOR, '', $file . DIRECTORY_SEPARATOR).'<br>');
						$zip->addFromString(str_replace($source . DIRECTORY_SEPARATOR, '', $file), file_get_contents($file));
					}
				}
			} else if (is_file($source)) {
				$zip->addFromString(basename($source), file_get_contents($source));
			}
		}
		return $zip->close();
	}
}
return false;

}`

In the same lane.
What about a backup program which takes files from a dir and all subdirs newer than a specific date and zips it.

I cant get it to work. is this not working with newer PHP versions? 7.2?

is this code can create zip up 10 GB files into backup of any sites ?
