Question

I am generating an array from a while loop, and I would like to eventually use this array to display data.

while($row = $database->fetch(PDO::FETCH_ASSOC)
{

     $value_1 = $row['value_1'];
     $value_2 = $row['value_2'];

     $data[] = array("value_1"=>$value_1,"value_2"=>$value_2);

}

so the $data[] would display using print_r I get something like this:

Array
(
    [0] => Array
        (
            [value_1] => Hello World
            [value_2] => venus
        )

    [1] => Array
        (
            [value_1] => Hello World
            [value_2] => pluto
        )

    [2] => Array
        (
            [value_1] => Hello Moon
            [value_2] => Halloween
        )

)

My question is, how would I do a foreach loop or display such a way where if I wanted to get all data, but consolidate the same values?

Ex:

Hello World to venus pluto
Hello Moon to Halloween

I know those sentences doesn’t make sense, but as you can see Hello World would be consolidated and I would need to add an ” to” in between value_1 and value_2

Hope my question is understandable.

Thanks!

Try something like this. (Not Tested)

$match = array();
foreach($data as $d) {
    if (isset($match[$d['value_1']])) {
        $match[$d['value_1']] = $match[$d['value_1']].' '.$d['value_2'] ;
    } else {
        $match[$d['value_1']] = $d['value_1']. ' to '. $d['value_2'];
    }
}

print_r($match);
