return unique values from array
- by Brad
I have an array that contains cities, I want to return an array of all those cities, but it must be a unique list of the cities.
The array below:
Array
(
[0] => Array
(
[eventname] => Wine Tasting
[date] => 12/20/2013
[time] => 17:00:00
[location] => Anaheim Convention Center
[description] => This is a test description
[city] => Anaheim
[state] => California
)
[1] => Array
(
[eventname] => Circus
[date] => 12/22/2013
[time] => 18:30:00
[location] => LAX
[description] => Description for LAX event
[city] => Anaheim
[state] => California
)
[2] => Array
(
[eventname] => Blues Fest
[date] => 3/14/2014
[time] => 17:00:00
[location] => Austin Times Center
[description] => Blues concert
[city] => Austin
[state] => Texas
)
)
Should return:
array('Anaheim', 'Austin');
Any help is appreciated.
