instalar php en windows 10

Install the Visual C++ Redistributable for Visual Studio 2015—this is linked in the sidebar of the PHP for Windows Download page, but it's kind of hidden. If you don't do this, you'll run into a rather cryptic error message, VCRUNTIME140.DLL was not found, and php commands won't work.

1. Download PHP for Windows. I prefer to use 7.1.x (current release - 1), so I downloaded the latest Non-thread-safe 64-bit version of 7.1.x. I downloaded the .zip file version of the VC14 x64 Non Thread Safe edition, under the PHP 7.1 heading.
2. Expand the zip file into the path C:\PHP7.
3. Configure PHP to run correctly on your system:
   1. In the C:\PHP7 folder, rename the file php.ini-development to php.ini.
   2. Edit the php.ini file in a text editor (e.g. Notepad++, Atom, or Sublime Text).
   3. Change the following settings in the file and save the file:
      1. Change memory_limit from 128M to 1G (because Composer can use lots of memory!)
      2. Uncomment the line that reads ; extension_dir = "ext" (remove the ; so the line is just extension_dir = "ext").
      3. In the section where there are a bunch of extension= lines, uncomment the following lines:
         1. extension=php_gd2.dll
         2. extension=php_curl.dll
         3. extension=php_mbstring.dll
         4. extension=php_openssl.dll
         5. extension=php_pdo_mysql.dll
         6. extension=php_pdo_sqlite.dll
         7. extension=php_sockets.dll
4. Add C:\PHP7 to your Windows system path:
   1. Open the System Control Panel.
   2. Click 'Advanced System Settings'.
   3. Click the 'Environment Variables...' button.
   4. Click on the Path row under 'System variables', and click 'Edit...'
   5. Click 'New' and add the row C:\PHP7.
   6. Click OK, then OK, then OK, and close out of the System Control Panel.
5. Open PowerShell or another terminal emulator (I generally prefer cmder), and type in php -v to verify PHP is working.

At this point, you should see output like:
