This document discusses advanced Git topics including patches, commands that generate diffs, rewriting history, bisecting, rerere, moving code, and plumbling. It also explains how Git stores content in blobs by compressing a header, content, and SHA-1 hash into a file in the .git/objects directory based on the hash. Contact information is provided for questions.

.substr($sha1, 0, 2)
.'/'.substr($sha1, 2);
$compressedContent = gzcompress($store);
if (!file_exists(dirname($path))) {
mkdir(dirname($path));
}
file_put_contents($path, $compressedContent);
