Using Ubuntu   Short answer   sudo apt-get install php7 2-json    or php7 1-json or  php5-json depending on the PHP version you re running   Then of course make sure you restart Apache   sudo service apache2 restart   Or if you are using PHP-FPM   sudo service php7 2-fpm restart    Or php7 1-fpm or php5-fpm   Explanation  Debian has removed the previous JSON extension as of PHP 5 5rc2 due to a license conflict   The JSON license has a clause which states      The Software shall be used for Good  not Evil    This causes a problem with Free Software Foundation s definition of free software which states      The freedom to run the program  for any purpose  freedom 0     FSF goes on to specifically list the JSON license as nonfree   Yes it seems a bit silly  Nevertheless Debian has removed the non-compliant JSON extension  and instead offered a replacement extension that is functionally equivalent   To be clear  PHP itself has NOT removed JSON  it s still in master  This is a distro   package manager issue   Rasmus makes it pretty clear      We have not removed json and we will never release a version of php without json support built in  Any changes in 5 5 is due to whatever distro packaging you are using which we have no control over    More details  http   iteration99 com 2013 php-json-licensing-and-php-5-5   http   liorkaplan wordpress com 2013 06 01 bye-bye-non-free-php-json-extension   https   bugs php net bug php id 63520  http   philsturgeon co uk blog 2013 08 fud-cracker-php-55-never-lost-json-support

you might also consider avoiding the core PHP module altogether   It is quite common to use the guzzle json tools as a library in PHP apps these days   If your app is a composer app  it is trivial to include them as a part of a composer build  The guzzle tool  as a library  would be a turnkey replacement for the json tool  if you tell PHP to autoinclude the tool   http   docs guzzlephp org en stable search html q json encode   http   apigen juzna cz doc guzzle guzzle function-GuzzleHttp json decode html
