Question

I’ve got the following code

foreach($reportsResult->getRecords() as $key => $reportRecord){
    $input = array($reportRecord->getField('Term').' - '.$reportRecord->getField('Year'));
    $result = array_unique($input);
    print_r($result);
}

which is producing output like

Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Winter - 2010 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Spring - 2011 )
Array ( [0] => Summer - 2011 )
Array ( [0] => Summer - 2011 )
Array ( [0] => Summer - 2011 )
Array ( [0] => Summer - 2011 )
Array ( [0] => Summer - 2011 )
Array ( [0] => Summer - 2011 )
Array ( [0] => Summer - 2011 )

What I would like to do, is just get the unique values, in this case Winter – 2010, Spring 2011, Summer 2011.

Could someone advise me how to do this, I thought array_unique might be the solution, but I guess its the way the way the values are stored in the array?

Answer 1

Why don’t you add the values to an array that’s defined outside the scope of the loop?

$array = array();

foreach($reportsResult->getRecords() as $key => $reportRecord){
    $array[] = $reportRecord->getField('Term').' - '.$reportRecord->getField('Year');
}

$array = array_unique($array);
