I recently stumbled upon composer, but I can't install it, I never used the command console. Installation off. The site does not work in any way. Help please install for OpenServer and for hosting. Can you still explain what "global installation" means?

We make sure that the PHP version is at least 5.3 , let's say it costs 5.6.
Open Advanced -> Configuration -> PHP 5.6
We are looking for the extension = php_openssl.dll string and make sure that it is not commented out (there is no semicolon before the line).
Open Extras -> Console, go to the current PHP module:
cd modules/php/PHP-5.6/ Then we execute the command:
php -r "readfile('https://getcomposer.org/installer');" | php If success, then in the console we see about the following:
All settings correct for using Composer Downloading 1.2.0 ... Composer successfully installed to: C: \ OpenServer \ modules \ php \ PHP-5.6 \ composer.phar Use it: php composer.phar
Check which version is the command:
php composer.phar -V In response, we can get something like:
Composer version 1.2.0 2016-07-19 01:28:52
The following command creates a .bat file for short reference to Composer:
echo @php "%~dp0composer.phar" %*>composer.bat Checking:
composer -V If everything is in order and you see the version again, then you can continue to use just composer instead of php composer.phar composer .
Probably the easiest way to check if a composer is installed or not is to enter the composer command, and the answer in the console will immediately become clear - if installed, you will see its logo:
______ / ____/___ ____ ___ ____ ____ ________ _____ / / / __ \/ __ `__ \/ __ \/ __ \/ ___/ _ \/ ___/ / /___/ /_/ / / / / / / /_/ / /_/ (__ ) __/ / \____/\____/_/ /_/ /_/ .___/\____/____/\___/_/ Thanks to everyone, I understood a lot, I learned a lot of new and unknown things for myself. I wrote a mistake in the terminal for a long time when I entered "composer" and similar commands, then I simply edited the PATH environment variable (indicated the path to my version of php in openserver and raised up for increased priority) and then I could easily use the composer from any point. As it turned out, it was not necessary to install it at all, because of the installation, it stopped working for me, because In OpenServer already have everything.
Опенсервер>Меню>Дополнительно>КонсольYou will see the current directory where your Openserver is installed (I have it installed in d: \ openserver). Run thecomposer helpcommand and you will see the help window on the composer. If everything went exactly as I described - the composer works for you, and the maximum that you have to do is update its version with the command (if I'm not mistaken)composer update. - Edward
