)

)
< /code>

Und ich versuche, es nach dem Wert "Dezimal" zu sortieren. < /p>

Ich habe eine Funktion erstellt Eine Sortierung nach dem Dezimalwert zu machen, aber aus irgendeinem Grund, wie Sie durch mein obiges Array sehen können, ist es nicht ganz sortiert, in dem 0,86 ein besserer Wert als 0,85 ist. />usort($outcomes, 'sort_by_decimal');
function sort_by_decimal ($a, $b)
{
return $a['Decimal'] - $b['Decimal'];
}
< /code>

Danke. < /p>
