2. Select the path to the folder where your Php.exe is located

3. Direct Click Next

4. Click Install

5. Click Finish

6. Open cmd and enter composer directly: The following indicates the successful installation

Three. Use:

For example, my project under the C:\Users\Administrator\Desktop\phpstudy\phpcode\20, plainly is in the ' 20 ' This folder,

I would like to use composer to manage components under this folder now, what should I do?

1. Create a Composer.json file in the ' 20 ' folder, which contains information about all of your components. The contents of this file are as follows:

I added three components that I wanted to use.

{"  require": {    "guzzlehttp/guzzle""4.2.*",//Front is the component name, followed by component version    "league/ CSV"" 6.0.*",//php components, component name and version can be obtained from https://packagist.org/"    spatie/string"" 1.8.* "}}

2. In the cmd command line, go to the ' 20 ' directory,

3. Execute the Composer install command on the cmd command line and he will download the 3 components in the Composer.json file under the ' 20 ' folder automatically.

The results are as follows:

As you can see, he automatically generates a vendor folder, and the components are all downloaded under vendor.

Four. Use of components:

1. First in the file to introduce vendor under the autoload.php file, which is the official automatic loading file.

2.new object, the method can be called.

Such as:

' vendor/autoload.php ';     Introduction of automatic Loading file$client= \guzzlehttp\client ();  Creating an object for a guzzlehttp component

$httpResponse = $client->options ();  Calling methods

Five. It is very slow to download the components, which requires modifying the composer configuration file:

1. Enter the composer Config-l-G command in CMD to get the path to the composer configuration file.

The "Home" in the picture is followed by a path,

2. Open the Config.json file under path. Change the content to:

{            "config": {            },            "repositories": [                {"type": "Composer", "url": "http://pkg.phpcomposer.com/repo/ packagist/"},                {" Packagist ": false}            ]}

It is good to change the URL path to the available domestic path. A few more try to change a few.
