Unix command-line JSON parser?

If I have a config file in JSON and a PHP script to flatten the config file into something like this

database_dbname=sensei
database_password=somerandompassword
memcached_host=localhost
....

can I pipe this to my bash script and make each of the entry above as a variable?

./bin/flatten_config.php config.json | ./bin/my_bash_script.sh

so that in my bash-script I can use values from the config file

mysql -D${database_dbname} -p${database_password} ...

In bash you could write in your script-file

source <(./bin/flatten_config.php config.json)

bash will take the output of flatten_config.php and parse it like input
