git果

php 5.3.2(openssl extension)


*nix 發php'>r'"copy('https://getcomposer.org/installer',''composer>setup.php');"'php'>r'"..."'php'composer>setup.php'php'>r'"unlink('composer>setup.php');"

installer' 不發太 'Composer' 樣能樣網 'composer.phar'

會

mv'composer.phar'/usr/local/bin/composer'composer' 不想學

https://getcomposer.org/download/'

https://getcomposer.org/download/


Windows 發• 中 Composer 起 for Windows

• 那起看能同看 Composer 那 PHP網起 php.exe

道網 PHP 道起⼼心

https://getcomposer.org/Composer>Setup.exe

https://getcomposer.org/Composer-Setup.exe


wagon 已• wagon Laravel 享 PHP/Laravel 發

網去 Cmder因Composer因git AMP網 wagon網家 wagon Cmder

已 Composer

P.S'wagon' 去 'cmder'發中 'Composer'發不網今不⼼心

http://www.laravel>dojo.com/opensource/wagon Laravel wagon與

http://www.laravel-dojo.com/opensource/wagon


再• Composer PHAR 再 (PHP archive)網感 PHP Runtime 有 ( )

• composer.phar 道成會網想學與

$'php'composer.phar'[command]


• 想學著增網想學與$'[php]'composer[.phar]'[>>version]


Composer• 上 Composer網 bug-

fix$'[php]'composer[.phar]'self>update


PHP • HTTP PHP CLI PHP

個 CLI PHP 個 CLI PHP 定$'php'>v $'php'>r'"echo'PHP_BINARY;"


次 extension• HTTP CLI php.ini

個 CLI PHP php.ini ⼼心

$'php'>>ini

個 CLI extension

$'php'>m


XDebug 今下• Composer XDebug

alias 過 XDebug

alias'composer='php'>n'/usr/local/bin/composer'⽣生網都做 ^.<

ComposerComposer 啊⼼心


Composer • 為成會

• Composer

$'cd'~/Code/{MyProject}

$'composer'init(那給 'composer.json)


{'''''"name":'"{vendor/package}",'''''"type":'"project",'''''"license":'"proprietary",'''''"authors":'['''''''''{'''''''''''''"name":'"{author'name}",'''''''''''''"email":'"{author'email}"'''''''''}'''''],'''''"minimum>stability":'"stable",'''''"require":'{'''''''''"{vendor/package}":'"{version}"'''''},'''''"autoload":'{}'}

Composer ⼼心再


時⼈人• PHP 都與Packagist.org

^與 ^嗎 Composer 網上中 Copmposer


所多得• 網 composer'require

• 樣 composer.json 網 composer'validate

• 情這網太⽂文 dev-master 的 * ( 全在裡 Packagist )

• ⼿手把 SemVer ⾏行 ( 享很把)

• 樣所多樂網中Packagist Semver Checker 多

http://semver.mwl.be/


json 再 lock 再!?年 commit VCS


• composer.json

- 那⼼心• composer.lock

- 知• vendor

- 起


(lock'再 )

After'installing'the'dependencies,'Composer'writes'the'list'of'the'exact'versions'it'installed'into'a'composer.lock'file.

This'locks'the'project'to'those'specific'versions.


VCS

update install

json V.S lock


/vendor'/node_modules'composer.phar

.gitignore

(Jordi' 'lock'再果 )


install 的 update想學歡網 …


1. 'composer.lock' 太最 '2. 最網 'composer'update' '3.最網那 'lock' 'package'

$'[php]'composer[.phar]'install


1. 'composer.json'再'2. ⼼心網作 ''3. 作 'packages'4. 'composer.lock

$'[php]'composer[.phar]'update


• $'composer'install

- (git'clone) 網那

• $'composer'update

- composer.json

-

( composer.lock 再)

( 那快沒後第 )

不多起

發$'composer'require'vlucas/phpdotenv

• 說多起• 都不網說都都

• 起網⼼心說

可說對$'composer'require'fzaninotto/faker

• 多說對起網每說對 aaa因xxx因asdf 我說對

• 剛因無說對• 網可說對
