var2zip is a PHP class for creating simple Zip archives in RAM.

• PHP 8.0+
• ZLIB extension (optional)

• Maximum entry size is 4 GiB
• Directories are not supported

Create a new instance:

$var2zip = new \xenocrat\var2zip();

Add an entry read from disk:

$file = file_get_contents("README.md");
$var2zip->add("README.md", $file);

Add an entry with last-modified timestamp:

$modified = strtotime("1982-09-09T20:19:11Z");
$var2zip->add("hello.txt", "Hello, world!", $modified);

Set the compression level (1-9, or 0 to disable):

$var2zip->compression_level = 9;

Export the Zip archive and write to disk:

$zip = $var2zip->export();
file_put_contents("archive.zip", $zip);
