本篇內(nèi)容介紹了“PHP工具Composer的安裝與使用方法”的有關(guān)知識(shí),在實(shí)際案例的操作過(guò)程中,不少人都會(huì)遇到這樣的困境,接下來(lái)就讓小編帶領(lǐng)大家學(xué)習(xí)一下如何處理這些情況吧!希望大家仔細(xì)閱讀,能夠?qū)W有所成!
PHP Composer 安裝
系統(tǒng)需求:
Composer 需要PHP5.3.2+ 以上的環(huán)境來(lái)運(yùn)行。有幾個(gè)敏感的PHP設(shè)置和編譯標(biāo)志也是必需的,但安裝程序會(huì)發(fā)出警告當(dāng)存在任何不兼容的情況。
比如PHP的擴(kuò)展的要求是,安裝或重新編譯php without –disable-phar
為了從源地址安裝軟件包,而不是簡(jiǎn)單的壓縮文件包,您將需要安裝軟件包的版本控制工具,比如git、svn或hg等。
Composer 是兼容多平臺(tái)的,其運(yùn)行適用于Windows,Linux和OSX。
安裝失敗的錯(cuò)誤消息:
curl -sS https://getcomposer.org/installer | PHP #!/usr/bin/env php some settings on your machine make Composer unable to work properly. Make sure that you fix the issues listed below and run this script again: The phar extension is missing. Install it or recompile php without –disable-phar Your PHP (5.2.9) is too old, you must upgrade to PHP 5.3.2 or higher.
我的本地默認(rèn)開(kāi)發(fā)環(huán)境是PHP 5.2.9,當(dāng)我嘗試在PHP 5.2.9上安裝時(shí),提示版本過(guò)低,需要升級(jí)到PHP 5.3.2 或者更高的版本。
于是我下載XAMPP 1.7.7 usb lite 版本。
E:\USB\Dropbox\phpstorm\php53>E:\USB\xampp_177\php\php.exe -v PHP 5.3.8 (cli) (built: Aug 23 2011 11:50:20) Copyright (c) 1997-2011 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2011 Zend Technologies
XAMPP 1.7.7 下的PHP環(huán)境是5.3.8。確認(rèn)我的PHP環(huán)境大于等于PHP5.3.2后。
PHP 5.3 安裝 Composer
E:\USB\Dropbox\phpstorm\php53>curl -sS https://getcomposer.org/installer | E:\USB\xampp_177\php\php.exe #!/usr/bin/env php Some settings on your machine may cause stability issues with Composer. If you encounter issues, try to change the following: The openssl extension is missing, which will reduce the security and stability o f Composer. If possible you should enable it or recompile php with –with-openssl Downloading… Composer successfully installed to: E:\USB\Dropbox\phpstorm\php53\composer.phar Use it: php composer.phar
注意:
我關(guān)閉了XAMPP 1.7.7 Apache的SSL模塊,所以Composer提示我警告,為了安全因素建議我開(kāi)啟SSL模塊。不開(kāi)啟也不影響使用。
安裝時(shí)的參數(shù) | PHP,一定要更改為真實(shí)的PHP環(huán)境路徑,比如 | E:\USB\xampp_177\php\php.exe
使用Composer為PHP路徑 + 命令,在我們安裝的環(huán)境中,使用方法為:E:\USB\xampp_177\php/php.exe composer.phar 命令。
我安裝的環(huán)境是在Windows下,如果在Linux下,而PHP 5.3 環(huán)境也不在默認(rèn)PHP命令下時(shí),應(yīng)該采用 | /usr/php/53/usr/bin/php,例如:
curl -sS https://getcomposer.org/installer | /usr/php/53/usr/bin/php
安裝完成后,檢查安裝版本。
E:\USB\Dropbox\phpstorm\php53>E:\USB\xampp_177\php/php.exe composer.phar -V Composer version 0209bd31a0ac3aeb2a68fc81e2d03c71072bef33
檢查PHP Composer命令:
E:\USB\Dropbox\phpstorm\php53>E:\USB\xampp_177\php/php.exe composer.phar ______ / ____/___ ____ ___ ____ ____ ________ _____ / / / __ \/ __ `__ \/ __ \/ __ \/ ___/ _ \/ ___/ / /___/ /_/ / / / / / / /_/ / /_/ (__ ) __/ / \____/\____/_/ /_/ /_/ .___/\____/____/\___/_/ /_/ Composer version 0209bd31a0ac3aeb2a68fc81e2d03c71072bef33 Usage: [options] command [arguments] Options: –help -h Display this help message. –quiet -q Do not output any message. –verbose -v Increase verbosity of messages. –version -V Display this application version. –ansi Force ANSI output. –no-ansi Disable ANSI output. –no-interaction -n Do not ask any interactive question. –profile Display timing and memory usage information –working-dir -d If specified, use the given directory as working directory . Available commands: about Short information about Composer archive Create an archive of this composer package config Set config options create-project Create new project from a package into given directory. depends Shows which packages depend on the given package diagnose Diagnoses the system to identify common errors. dump-autoload Dumps the autoloader dumpautoload Dumps the autoloader help Displays help for a command init Creates a basic composer.json file in current directory. install Installs the project dependencies from the composer.lock file if present, or falls back on the composer.json. list Lists commands require Adds required packages to your composer.json and installs the m run-script Run the scripts defined in composer.json. search Search for packages self-update Updates composer.phar to the latest version. selfupdate Updates composer.phar to the latest version. show Show information about packages status Show a list of locally modified packages update Updates your dependencies to the latest version according to composer.json, and updates the composer.lock file. validate Validates a composer.json
這樣我們?cè)赑HP5.3環(huán)境下的Composer已經(jīng)安裝完成。
類(lèi)似的方法我們也可以安裝PHP 5.4的環(huán)境上。
PHP 5.4 安裝 Composer
下載XAMPP 1.8.1 usb lite 版本,將得到PHP5.4.7環(huán)境。
E:\USB\Dropbox\phpstorm\php53>E:\USB\xampp_181\php\php.exe -v PHP 5.4.7 (cli) (built: Sep 12 2012 23:48:31) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies
確定版本高于PHP 5.3.2 后,開(kāi)始安裝:
E:\USB\Dropbox\phpstorm\php54>curl -sS https://getcomposer.org/installer | E:\USB\xampp_181\php\php.exe #!/usr/bin/env php Some settings on your machine may cause stability issues with Composer. If you encounter issues, try to change the following: The openssl extension is missing, which will reduce the security and stability o f Composer. If possible you should enable it or recompile php with –with-openssl Downloading… Composer successfully installed to: E:\USB\Dropbox\phpstorm\php54\composer.phar Use it: php composer.phar
安裝完成后,檢查安裝版本。
E:\USB\Dropbox\phpstorm\php54>E:\USB\xampp_181\php/php.exe composer.phar -V Composer version 0209bd31a0ac3aeb2a68fc81e2d03c71072bef33
這樣,PHP 5.4 環(huán)境下的Composer也安裝成功了。
PHP Composer 使用
這里我只簡(jiǎn)單演示使用PHP Composer安裝Symfony框架。
首先大概講解一下命令的標(biāo)準(zhǔn)格式:
php composer.phar create-project symfony/framework-standard-edition path/ 2.2.1
第一個(gè)參數(shù)PHP為本地PHP開(kāi)發(fā)環(huán)境,指向PHP運(yùn)行命令。
第二個(gè)參數(shù),為composer.phar方式下載。
第三個(gè)參數(shù),為動(dòng)作命令,例如create-project,目的是為了創(chuàng)建一個(gè)新的項(xiàng)目從一個(gè)軟件包到指定目錄。
第四個(gè)參數(shù),為本地安裝的目錄。
第五個(gè)參數(shù),為安裝軟件包的版本。
根據(jù)上述我們?cè)赑HP5.4環(huán)境下安裝的Composer,我們的安裝命令為:
E:\USB\Dropbox\phpstorm\php54>E:\USB\xampp_181\php/php.exe composer.phar create-project symfony/framework-standard-edition E:\USB\xampp_181\htdocs\Symfony 2.2.1
安裝結(jié)果:

從命令行結(jié)果,我們看到了整個(gè)Symfony框架的安裝過(guò)程與結(jié)果。
PHP Composer 定義依賴(lài)關(guān)系
Composer在使用時(shí)會(huì)自動(dòng)尋找composer.json這個(gè)文件。 composer.json將用來(lái)定義整個(gè)項(xiàng)目的依賴(lài)包。例如:
{ "require": { "monolog/monolog": "1.2.*" } }
依賴(lài)包簡(jiǎn)單的說(shuō)明,我們的項(xiàng)目需要一些從1.2開(kāi)始的任何版本的monolog/monolog包。
Composer是PHP中的一個(gè)依賴(lài)關(guān)系管理工具。通過(guò)Composer我們可以在發(fā)布軟件時(shí)節(jié)省大量的文件數(shù)目和控制依賴(lài)包的版本。
