# Key Value Store PHP

kvs-php is a rudimentary key/value store written in PHP.

# Getting the project

You can get a copy of this project by clicking on the
[ZIP](http://git.dlma.com/kvs-php.git/zipball/master)
or [TAR](http://git.dlma.com/kvs-php.git/tarball/master) buttons
near the top right of the GitList web page.

If you're me, and you want to contribute to the repo, then you can clone it like so:

    git clone ssh://USERNAME@dlma.com/~/git/kvs-php.git

# Building it

1. Ensure your server's version of PHP supports PDO and SQLite.
2. Move config.php.sample to config.php, and replace `replaceme` with a passcode you choose.
3. Optional: Use secure HTTP. I recommend getting a free SSL certificate from [Let's Encrypt](https://letsencrypt.org/).

# Using it

Here is [a live instance that serves an index page](https://kvs-php.dlma.com/).  You can send a key to get a value like so:

    https://kvs-php.dlma.com/?k=1Gxxxxxxxxxx

Special use case, here's how to get the value for the most-recently updated key of a list of keys. The list could contain any number of keys, but only one value will be returned. 

    https://kvs-php.dlma.com/?k=1Gxxxxxxxxxx,1Gxxxxxxxxxz

Here's the recipe for a cURL command to store a new value for a key: 

    curl --data "key=value&auth={authorization}" https://{url}

Here's [the source code for a Roku channel client of such a service](http://git.dlma.com/roku_ip_tagger.git/). 

# Trouble shooting

If you get the error "Exception : SQLSTATE\[HY000] \[14] unable to open database file", then [PHP's owner probably doesn't match the directory's owner](https://stackoverflow.com/questions/5165183/apache-permissions-php-file-create-mkdir-fail). You may be able to fix it by noting PHP's owner from phpinfo(), and then invoke "sudo chown phpowner:phpowner (appropriate\_target)".
