Missing PHP extensions in local windows 10 Magento Installation

Question

I'm trying install Apache + PHP + Magento2.1 + MySQL in Windows 10.

I've already installed:

      Magento-CE-2.1.8_sample_data
              Content saved in C\Apache24\htdocs
      Apache-2.4.27-Win64-VC15.zip
              Directory: C\Apache24
      PHP Version 5.6.31 php-5.6.31-Win32-VC11-x64.zip
              Directory: C:\PHP
       mysql-community-5.7.19 (Msi installer)

In the setup installation (Readiness Check) the follow errors are showed:

              PHP Extension curl.
              PHP Extension xsl.
              PHP Extension intl.
              PHP Extension mbstring.
              PHP Extension openssl.
              PHP Extension gd.

Answer 1

Versions from 5.6.0 to 5.6.4 are not supported. Only php 5 supported are from 5.6.5 and above.

I'd better suggest using php 7 to have better support also for your extensions

Check it better here

Otherwise, check better for the PHP modules you are enabling. According to this question you have to make sure that all the subsequent modules are enabled, and some are missing in your list.

PDO/MySQL
mbstring
mcrypt
mhash, 
simplexml, 
curl, 
gd2, 
ImageMagick 6.3.7 (or later) or both 
soap and
add xdebug.max_nesting_level=50000; at php.ini
