JSON not compiled in php

Question

I installed PHP Version 5.5.1-2 on Ubuntu 12.04 and JSON was not bundled with it (as far as I can tell).

I've read that I will have to reinstall php using the --enable-json or --with-json option.
So my questions are:

How can I verify JSON is not installed?

If not, do I reinstall php like this: apt-get install php --with-json (do I include --enable-json)?

Will my current settings be lost if I reinstall php?

Thanks

json support is there by default you should be able to use json_encode and json_decode with no problem have you tried to use them? — Patrick Evans

If you haven't already installed it:

sudo apt-get install php5-json

(more info: http://iteration99.com/2013/php-json-removed-from-php-5-5/ )

Shouldn't overwrite any other settings.

php -i | grep -i json returns nothing at all

Actually just try php -i and see if you get anything. You may not have php5-cli installed

Test if json_encode (or any of the other JSON functions) exist.

Either call it and observe an error or use function_exists("json_encode").

Response from call:Fatal error: Call to undefined function json_decode()

JSON is disabled then.

If I try to enable using extension=json I get the following: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/json' - /usr/lib/php5/20121212/json: cannot open shared object file: No such file or directory in Unknown on line 0

I guess you're missing the extension file. See if you can find it in the source installer or just reinstall PHP.

Ubuntu 12.04 doesn't support

sudo apt-get install php5-json

directly. the installer change it automatically to

sudo apt-get install php5-common

My recommandation should be to use sudo apt-get install php5-common instead of sudo apt-get install php5-json because sudo apt-get install php5-common will install also automatically all other dependencies for you
