        [grandTotalTopLevelCurrentYear] => 5398744.3
        [grandTotalTopLevelPreviousYear] => 0
    )   

)

And this code to sort it based on weightage

foreach ($finalArrayForAssetsSide as $k => $v) {
        $sort['weightage'][$k] = $v['weightage'];
    }
    if (count($finalArrayForAssetsSide) > 0) {
        array_multisort($sort['weightage'], SORT_ASC, $finalArrayForAssetsSide);
    }

I wan to sort it according to "weightage" of each Groups.But getting following Warning:

Warning: array_multisort(): Array sizes are inconsistent in /var/www/edubolderp/src/Edu/AccountBundle/Document/BudgetRepository.php line 3318

Please guide what is missing. Thanks in advance

Answer 1

Just use usort and provide a valid sort function. No need for array_multisort

usort($finalArrayForAssetsSide, function($a, $b) {
   return $a['weightage'] - $b['weightage'];
});
