PHP relies on the use of management tools composer

Today I saw a dependency management tool that introduced PHP, so we learned to try it out:

Environment: Win7

First, installation

1. Verify that PHP is enabled with the OpenSSL module (using HTTPS URLs);

Modify environment variable path, join c:\xampp\php

Open the command line and enter:

Php-version

Show:

Use the CD command to change the current path to the project root, and then run the command to download the installation:

Php-r "ReadFile (' Http://getcomposer.org/installer ');" | Php

I'm using the HTTP protocol URL here. If you have curl, you can also use the following command:

Curl-ss Https://getcomposer.org/installer | Php

Official website tips can also download the installation package Composer-setup.exe, unfortunately I see late, no trial.

To the project root, add the Composer.bat text file and execute it at the command line:

echo @php "%~dp0composer.phar"%*>composer.bat

Close and reopen the command line and enter the command:

Composer-v

You can see the version information for the output.

example, the project needs to use the output log library Monolog.

Create a Composer.json file within the project and enter the content:

{"    require": {        "Monolog/monolog": "1.0.*"    }}

Execute at cmd command line:

Composer Install

The required URLs may not be downloaded properly for some reason. It may be prompted by the following:

Failed to enable cryptofailed to open stream:operation Failed

You should consider solving your network problems at this time.

After successful operation, the Vendor folder appears in the project folder.

Examples of Use:

 
  Pushhandler (New Monolog\handler\streamhandler (' App.log ', monolog\logger::warning)); $log->addwarning (' Foo ');? >

Third, other

Update itself:

Composer Self-update

The above describes the use of PHP dependency management tool composer, including aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
