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
    )
)

Answer 1

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