Install JSON PHP Extension on CentOs or RedHat
Instead of serializing your code manually, that is writing your own classes and functions, there is a PHP extension that takes on most of the work for you. You just have to install it.
Since I had numerous requests for info and questions relating to JSON extension in CentOS. To enable these functions in RedHat and CentOs 5, the process is really simple and fast.
NOTE: As of PHP 5.2, json extension is now standard. If you’re running PHP 5.2 or later, or like to upgrade instead, you can skip this!
Steps to install json php extension
Ensure you have the necessary dependecies (php, php-pear, php-devel, gcc, make)
$ sudo yum install gcc make $ sudo yum install php php-pear php-devel
Use PECL (PHP Extension Community Library) to download the json package
$ sudo pecl download json
Use PEAR (PHP Extension and Application Repository) to extract and install the extension
$ sudo pear install json-1.2.1.tgz
Create a file in
/etc/php.d called “json.ini”, and add the following lines
; php-json extension extension=json.so
Restart apache (gracefully if you’re running a live site
$ sudo service httpd restart (or apachectl graceful, or apache2ctl graceful)
Check for availability by creating an info.php file in the web root with the following line:
<?php phpinfo(); ?>
Load info.php in your browser and check for JSON. You now should be all set, but if it doesn’t appear, verify all of the above steps very carefully.
Now load up your php info page and you should see the JSON extension listed. If not, make sure there were no errors in the steps above, and that you have reloaded Apache.
