Compression using zip

https://en.wikipedia.org/wiki/LZ77_and_LZ78

php -f zipme.php
unzip data.zip

php gunzipme.php

# CLI - GNUzip a file, note it replaces original file
gzip music-data.csv
gzip < music-data.csv > data.gz
# GNU unzip
gunzip data.gz 

# GNUzipping multiple files
# TapeAR(tar) puts the files together, while gzip then performs the compression.
# tar was originally developed to write data to sequential I/O devices with no file system of their own
tar cvf data.tar music-data.csv movie-data.csv

#extract(x) from tape archive
tar xvf data.tar 
x music-data.csv
x movie-data.csv

#tape archive and then GNU zip in a single command
tar -zcvf data.tar.gz music-data.csv movie-data.csv

php tape_archive_me.php
# creates archived_data.tar.gz
