之前在mac linux win10 安装运行未发现这样的奇奇怪怪的问题，随手记录下。
设置好php命令path
2个位置 administrator告知php安装版本执行文件exe目录，系统告知php.exe。（同一个版本的设置）
F:ddexecomposer>php -r "readfile('https://getcomposer.org/installer');" | php
PHP Warning: readfile(): Unable to find the wrapper "https" - did you forget to

设置php.ini 打开ssl设置 ;extension=php_openssl.dll
F:ddexecomposer>php -r "copy('https://install.phpcomposer.com/installer', 'co
mposer-setup.php');"
PHP Warning: copy(): SSL operation failed with code 1. OpenSSL Error messages:

需要证书
简答方法
浏览器直接地址访问下载
https://getcomposer.org/installer
下载后拉倒php.exe同目录下使用cmd命令
php installer
php -r "unlink('installer');"
或者是下载更新包
https://install.phpcomposer.com/composer.phar
下载后php.exe同目录下使用cmd命令
php composer-setup.php
php -r "unlink('composer-setup.php');"
或者对着composer文件进行
@php "%~dp0composer.phar" %*
如果找不到位置就使用
@php "F:ddexephpStudyphp70ncomposer.phar"
成功后写入bat
新建 composer.bat 文件 内容写入“@php "%~dp0composer.phar" %*” 保存，用管理员身份运行该文件。
或者cmd执行
echo @php "%~dp0composer.phar" %*>composer.bat
最后 检测是否安装成功
composer -V
