composer one

composer is a PHP package library dependency management tool. If you need to know more about it, you can check the information on the official website. For PHP, composer is really a good thing. Node and npm, Python has pip, and now PHP has also caught up! Let’s try it today

1. First install it

curl -sS https://getcomposer.org/installer | php

2. After the command is run, a composer.phar file will be generated in the current directory, move it Go to the /usr/local/bin directory and install it globally.
3. Create a new composer.json

<code>touch composer<span>.json</span>
vim composer<span>.json</span></code>

<code><span>"require"</span>:{
                <span>"monolog/monolog"</span>:<span>"1.2.*"</span>
                }

}
</code>

Generate the following files in the directory

<code>root<span>@66</span>f625feefa3:~<span># ls</span>
composer<span>.json</span>  composer<span>.lock</span>  vendor</code>

4. When you need to use monolog, introduce 'vendor/autoload.php' in php;

<code><span><span><?php</span><span>require</span><span>'/root/vendor/autoload.php'</span>;
<span>$log</span> = <span>new</span> Monolog\Logger(<span>'name'</span>);
<span>$log</span>->pushHandler(<span>new</span> Monolog\Handler\StreamHandler(<span>'app.log'</span>, Monolog\Logger::WARNING));

<span>$log</span>->addWarning(<span>'Foo'</span>);

<span>?></span></span></span></code>

5.ls View there Is app.log generated

<code>root<span>@66</span>f625feefa3:~<span># ls</span>
app<span>.log</span>  composer<span>.json</span>  composer<span>.lock</span>  test<span>.php</span>  test1<span>.php</span>  vendor
</code>

As expected, app.log is generated

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces composer 1, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.
