I haven't done anything about Composer for a long time. . . , composer hands-on...

About Composer - I haven’t used it for a long time. . . , composer takes action..

The first “blood” in June

Reading a book, I found that I like to read from the end, and then in PHP Classic Examples, the last chapter is about PEAR content. I checked on Zhihu and found that it’s over and out of date. It’s all about Composer, so let’s learn it

1. What

One sentence: Dependency management tool;

Explanation: It is convenient for you to download libraries, packages, etc., basically exclusive to PHP;

In addition, dependency management is just a name, but it seems to have a profound meaning: look at this http://www.infoq.com/cn/news/2011/05/ci-dependency-management/#anch68966

2. Installation

http://www.phpcomposer.com/

According to this, just install your own system and do it. What you need to know is that this thing is implemented on the command line;

My wamp has .exe directly, and then after installation find the composer.phar file for backup ;

3. Use

It is recommended to read the introduction of a Yii framework tool on imooc: http://www.imooc.com/learn/520

The key point is how to use: cd to the project file/create the project folder, and then .phar file path/composer.phar install yiisoft/yii 1.0.2

You have to study other in-depth information yourself.

A few common situations: problems that arise when you need to install the jquery package. Go to the corresponding package download page to find support: such as yii2

In addition, when you need a token for Github’s API, just go to Github to generate one and copy it over once;

In addition, each interruption will cause the file transfer to fail. Please delete the previous file before executing the command again;

In addition, it is best to match the Chinese image first to speed up, otherwise you will know the external network. . . For specific information, packagist Chinese website has it: http://www.phpcomposer.com/

The configuration is here, one command is all it takes, I like this sour feeling: http://pkg.phpcomposer.com/

<code class="language-bash hljs">composer config -g repo.packagist composer https://packagist.phpcomposer.com</code>

The above, but I’ve been really lazy lately. . .
