Basic primer on associative arrays in php.
To create an associative array, define it all at once like this:
$arr = array(
'key' => 'value',
'otherkey' => 1,
);
or you can assign one value at a time
$arr = array();
$arr['key'] = 'value';
$arr['otherkey'] = 1;
You can always add or change a current value using:
$arr['newkey'] = 2;
$arr['key'] = 1;
Remember if you use array sort functions to use the ones that keep the associative keys intact like: uasort(), ksort(), and asort()
You can use associative arrays for many things, from holding simple data to multiple nested levels for configuration.
