i.e --- o/p should be 9

how to get this index. Please help me

Thanks

  • @PLB I don't know how to traverse in this array so that first I check it's name and then get it's parent array index that's why I am asking.Thanks Commented Jul 12, 2013 at 4:56
  • Is it already defined that your values will be located in the first dimension of the array ? Or it should be used to find values in $array[$i][$j][$k][$etc] ? Commented Jul 12, 2013 at 4:59
  • @Frederik.L I have 'name' .Can you write your code which will work?Thanks Commented Jul 12, 2013 at 5:04

I think you are looking for this:

function getIndex($name, $array){
    foreach($array as $key => $value){
        if(is_array($value) && $value['name'] == $name)
              return $key;
    }
    return null;
}

$index = array_search( $value, array_column( $array, 'name' ) ); I think this work too .
