FTP deployment is a tool for automated deployment to an FTP server.

There is nothing worse than uploading web applications to FTP server manually, using tools like Total Commander. (Although, editing files directly on the server and then trying to keep some kind of synchronization is even worse ;-)

Once the process is automated, it costs you a fraction of time and minimizes the risk of error (didn't I forget to upload some files?). There are lots of sophisticated deploying techniques available today, but many people are still using FTP. This tool is designed for them.

FTP Deployment is a script written in PHP (requires PHP 5.4 or newer) and will automate the entire process. Just say which local folder to upload and where. This information is stored in a deployment.ini text file, which you can associate with deployment.php script, so deployment will become a one click thing.

php deployment.php deployment.ini

And what does the deployment.ini file contain? Only the remote item is required, all the others are optional:

; log file (defaults to config file with .log extension)
log = ...

; directory for temporary files (defaults to system's temporary directory)
tempdir = /temp/deployment

; enable colored highlights? (defaults to autodetect)
colors = yes

[my site] ; Optional section (there may be more than one section).
; remote FTP server
remote = ftp://user:secretpassword@ftp.example.com/directory
; you can use ftps:// or sftp:// protocols (sftp requires SSH2 extension)

; FTP passive mode
passivemode = yes

; local path (optional)
local = .

; run in test-mode? (can be enabled by option -t or --test)
test = no

; files and directories to ignore
ignore = "
    .git*
    project.pp[jx]
    /deployment.*
    /log
    temp/*
    !temp/.htaccess
"
; is the script allowed to delete remote files? (defaults to yes)
allowdelete = yes

; jobs to run before file upload
before[] = local: lessc assets/combined.less assets/combined.css
before[] = http://example.com/deployment.php?before

; jobs to run after file upload
after[] = remote: unzip api.zip
after[] = http://example.com/deployment.php?after

; directories to purge after file upload
purge[] = temp/cache

; files to preprocess (defaults to *.js *.css)
preprocess = no

; file which contains hashes of all uploaded files (defaults to .htdeployment)
deploymentfile = .deployment

Configuration can also be stored in a PHP file.

In test mode (with -t option) uploading or deleting files is skipped, so you can use it to verify your settings.

Item ignore uses the similar format to .gitignore:

log - ignore all 'log' files or directories in all subfolders
/log - ignore 'log' file or directory in the root
app/log - ignore 'log' file or directory in the 'app' in the root
data/* - ignore everything inside the 'data' folder, but the folder will be created on FTP
!data/db/file.sdb - make an exception for the previous rule and do not ignore file 'file.sdb'
project.pp[jx] - ignore files or folders 'project.ppj' and 'project.ppx'

Before the upload starts and after it finishes, you can execute commands or call your scripts on the server (see before and after), which can, for example, switch the server to a maintenance mode. If you use php-config - you can run lambda function with deployment environment.

Syncing a large number of files attempts to run in (something like) a transaction: all files are uploaded with extension .deploytmp and then quickly renamed.

An .htdeployment file is uploaded to the server, which contains MD5 hashes of all the files and is used for synchronization. So the next time you run deployment.php, only modified files are uploaded and deleted files are deleted on server (if it is not forbidden by the allowdelete directive).

Uploaded files can be processed by a preprocessor. These rules are predefined in the deployment.php file: .css files are compressed using the YUI Compressor and .js minified by Google Closure Compiler. These tools are already included in the distribution, however, they require the presence of Java.

There is also a rule for expanding mod_include Apache directives. For example, you can create a file combined.js:

<!--#include file="jquery.js" -->
<!--#include file="jquery.fancybox.js" -->
<!--#include file="main.js" -->

This tool will combine scripts together and minify them with the Closure Compiler to speed-up your website.

In the deployment.ini, you can create multiple sections, i.e. you may have separate rules for data and for application.
