Search array and return all keys and values when match found

Question

I like to perform a search on an array and return all values when a match is found. The key [name] in the array is what I am doing a search on.

Array (
[0] => Array
    (
        [id] => 20120100
        [link] => www.janedoe.com
        [name] => Jane Doe
    )
[1] => Array
    (
        [id] => 20120101
        [link] => www.johndoe.com
        [name] => John Doe
    )
)

If I did a search for John Doe it would return.

Array
(
    [id] => 20120101
    [link] => www.johndoe.com
    [name] => John Doe
)

Would it be easier to rename the arrays based on what I am searching for. Instead of the above array I can also generate the following.

Array (
[Jane Doe] => Array
    (
        [id] => 20120100
        [link] => www.janedoe.com
        [name] => Jane Doe
    )
[John Doe] => Array
    (
        [id] => 20120101
        [link] => www.johndoe.com
        [name] => John Doe
    )
)

You run the chance of having duplicate keys if you use names for your keys. — BenOfTheNorth, Feb 25 '12 at 00:21
Than I will ignore the second idea and search just the first array. — Tim, Feb 25 '12 at 00:26

$filteredArray = 
array_filter($array, function($element) use($searchFor){
  return isset($element['name']) && $element['name'] == $searchFor;
});

Requires PHP 5.3.x

As a function: `function so9439905_filter_array($array, $field, $search) { $filtered_array = array_filter($array, function($element) use($field, $search) { return isset($element[$field]) && $element[$field] == $search; }); return $filtered_array; };` Call via `so9439905_filter_array($array, 'name', 'John Doe');` – Leander Oct 04 '21 at 12:42

I would like to offer an optional change to scibuff's answer(which was excellent). If you are not looking for an exact match, but a string inside the array...

function array_search_x( $array, $name ){
    foreach( $array as $item ){
        if ( is_array( $item ) && isset( $item['name'] )){
            if (strpos($item['name'], $name) !== false) { // changed this line
                return $item;
            }
        }
    }
    return FALSE; // or whatever else you'd like
}

Call this with...

$pc_ct = array_search_x($your_array_name, 'your_string_here');

$array = Array (
  [0] => Array(
    [id] => 20120100,
    [link] => www.janedoe.com,
    [name] => 'Jane Doe'
  ),
  [1] => Array(
    [id] => 20120101,
    [link] => www.johndoe.com,
    [name] => 'John Doe'
  )
);
$i = 0;
$new_array = [];
foreach($array as $key => $value){
  if($value['name'] === 'John Doe'){
    $key = $value['name'].$i;
    $new_array[] = [$key => $value];
    $i ++;
  }
}
return $new_array;
