The one-liner:

dd if=/dev/zero bs=1G count=10 | gzip -c > 10GB.gz

This is brilliant.

ow.. now the idea is to unzip it right?

nice idea:

if (ipIsBlackListed() || isMalicious()) {
    header("Content-Encoding: deflate, gzip");
    header("Content-Length: "+ filesize(ZIP_BOMB_FILE_10G)); // 10 MB
    readfile(ZIP_BOMB_FILE_10G);
    exit;
}

Might need some

if (ob_get_level()) ob_end_clean();

before the readfile. ๐Ÿ˜‰
