PHP JSON Module Bug Fix

If you are encountering any weird stuff with your PHP-JSON module installation, you might want to reinstall JSON using this link, this might get rid of the bug that is pestering you and your application.

First, uninstall any previous JSON installation you have so as not to conflict with the new one. To make sure you got the old JSON out, check your list of PHP modules by running:

php -m

JSON should not be listed and make sure you do not see any errors either. Doing this will prevent further headaches, trust me.

Perform the following steps to install the bug-free version of JSON from source:

1. Download the JSON source from here. You can use wget to download the source if you are using CLI

wget http://aurore.net/projects/php-json/php-json-ext-1.2.1.tar.bz2

2. Uncompress the archive and change directory.

tar jxf php-json-ext-1.2.1.tar.bz2
cd php-json-ext-1.2.1

3. Run phpize. Make sure that phpize is installed before proceeding to this step. phpize is included in the php-devel package.

phpize

4. Configure, make and make install

./configure
make
make install

JSON is now installed, but make sure that json.so is loaded in your php.ini file.

1. Open php.ini file. If you are unsure about the location of your php.ini file, run

php -i | grep php.ini

You should see something like this:

Loaded Configuration File => /etc/php.ini

2. Add this at the last line of the configuration file:

extension=json.so

3. You might want to restart Apache to make sure everything is still working.

To check if JSON is loaded as module, run php -m again, make sure JSON is in the list.

Now, to test JSON, open an editor and copy these lines:

< ?php
$input = '{ "test" : 12121211212121 }';
$val = json_decode($input, true);
print $val["test"];
?>

Save the file (json-test.php is the filename in this case).

Execute the file by running php json-test.php

The result should be 12121211212121
