I'm dealing with php array and I have proplem with get the index of parent array. Here I want to find parent index of title so I try find it by loop but I failed find index if the title is array. How I can get the parent index if the title is array

<?php
$Arr = [
    [
        "title" => ["news", "nasional", "internasional", "regional", "metropolitan", "sains", "pendidikan"],
        "url" => "AAA",
    ],
    [
        "title" => ["seleb", "news"],
        "url" => "BBB"
    ],
    [
        "title" => "travel",
        "url" => "CCC"
    ]
];


foreach($Arr as $value) {
$key = array_search("seleb", array_column($Arr , 'title'));
    echo $key; // should return index parent is [1]
}

?>

Try this to find the parent index

$Arr = [
        [
          "title" => ["news", "nasional", "internasional", "regional", "metropolitan", "sains", "pendidikan"],
          "url" => "AAA",
       ],
       [
         "title" => ["seleb", "news"],
         "url" => "BBB"
       ],
       [
         "title" => "travel",
         "url" => "CCC"
       ]
      ];

   foreach($Arr as $key => $value) {
     if(is_array($value['title'])){
        if(in_array("seleb", $value['title']))
           echo $key;
     }
   }

Search for value in multidimensional array and get parent array in PHP, This solution will depend into two conjugated loops. <?php function searchIt($arr, $searchItem){ $result = array(); $resultIndex = 0; for ($i =0; $i < count($arr);  public static int IndexOf (Array array, object value); static member IndexOf : Array * obj -> int. The one-dimensional array to search. The object to locate in array. The index of the first occurrence of value in array, if found; otherwise, the lower bound of the array minus 1. ArgumentNullException. array is multidimensional.

You are passing the whole array instead of it pass the current value of the loop

foreach ($Arr as $key => $value) {
    $keyChild='';
    $keyChild = array_search("seleb", $value);
    if ($keyChild != null && empty($keyChild)) {
        echo $key;
    }
}

fastest way to get parent array key in multidimensional arrays with , what is the best way to get parent array key with multidimensional arrays? for As you can't index an array (in the search meaning of index) then you're  Multidimensional Arrays. As the name indicates, multi dimensional arrays are arrays that contain more than one dimension, usually two or three but it can have up to 32 dimensions. A multi array works like a matrix with various levels, take in example a comparison between one, two, and three Dimensions.

Here's another way of doing it with a little less nesting and a bit more re-usability

<?php
$arr = [
    [
        "title" => ["news", "nasional", "internasional", "regional", "metropolitan", "sains", "pendidikan"],
        "url" => "AAA",
    ],
    [
        "title" => ["seleb", "news"],
        "url" => "BBB"
    ],
    [
        "title" => "travel",
        "url" => "CCC"
    ]
];

function findIndex($search, $array) {
    $found  = array_filter($array, function ($value) use ($search) {
        if (!is_array($value)) $value = [$value];
        return array_search($search, $value) !== false;
    });

    return key($found);
}

$titles = array_column($arr, 'title');
echo findIndex('seleb', $titles); // 1

findIndex will return the parent index or null deepening on whether the result is found or not.

Also this part:

$titles = array_column($arr, 'title');

Could be placed inside the function, with the 'title' being passed as another parameter.

array_keys - Manual, array_keys() returns the keys, numeric and string, from the array . Checks if the given key or index exists in the array; array_search() - Searches the array for Here's a way to find all the keys from a multidimensional array while keeping the​  n-dimension array can be an n-dimensional array of any type. If n-dimension array is an empty array, element or subarray returns the default value of the defined data type for the array. index 0..n-1 specifies a number that refers to a location within the input array. LabVIEW automatically provides an index input for each dimension of the array.

array_shift - Manual, array_shift() requires a re-index process on the array, so it has to run over all Here is a little function if you would like to get the top element and rotate the array​  @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 – Bhuvnesh Gupta Jul 12 '13 at 4:56 Is it already defined that your values will be located in the first dimension of the array ?

3 solutions for sorting multidimensional arrays by child keys or , 3 solutions for sorting multidimensional arrays by child keys or values programmers find really difficult is to sort multidimensional arrays by the built in ksort() function and use array values to re-index the array numerically. Figure 4: This is how you reference an individual item within a multi-dimensional array. That's just a quick demonstration of how you can set up multi-dimensional arrays in PowerShell.

How to check an array is multidimensional or not in PHP , This ensures that if there are one or more sub-arrays inside the parent array, the first element of the parent array (at index 0) will always be an array. Checking for​  Associative array stores the data in the form of key and value pairs where the key can be an integer or string. Multidimensional associative array is often used to store data in group relation. Creation: We can create a multidimensional associative array by mapping an array containing a set of key and value pairs to the parent key.

  • so you want to return parent index 0 and 1
  • I see, so we can treat key as parent index. thank you for sharing your thought
