Q: composer will not work with current setting PHP 7.1 / windows 10 windows 10 / php 7.1
running composer setup "https://getcomposer.org/doc/00-intro.md#installation-windows" I get an error.
composer will not work with current setting
1)
php 7.1 has 'C:\php\ext\php_mysqli.dll' and it is no longer has
'C:\php\ext\php_mysql.dll'
2)
imagick is installed and the file 'php_imagick.dll' is in the c:\php\ext folder 
thanks for any help on this...
here is the full error

The PHP exe file you specified did not run correctly:
C:\php\php.exe
The php.ini used by your command-line PHP is: C:\php\php.ini
A setting in your php.ini could be causing the problem: Either the 'extension_dir' value is incorrect or the dll does not exist.
Program Output:
PHP Warning:  PHP Startup: Unable to load dynamic library 'C:\php\ext\php_mysql.dll' - The specified module could not be found.
