Case insensitive search in PHP array

I want to search for Mobile or mobile legend or mobile. it should return both of the arrays. But my code only works if I search for the exact same word. Please help.

$resutls = [];
$words = ['mobile', 'Mobile Legend', 'Mobile', 'mobile legend']; 

foreach ($items as $item) {
   if(in_array($item['CategoryName'], $words)) {
      $results[] = $item;
   }
}
print_r($results);


[0] => Array
        (
            [id] => 1
            [Name] => Mobile Game,
            [CategoryName] => Mobile Legend
        )
     [1] => Array
        (
            [id] => 2
            [Name] => Laptop Game
            [CategoryName] => Mobile
        )

This probably is what you are looking for: 

<?php
$searchTerms = ['mobile', 'Mobile Legend', 'Mobile', 'mobile legend'];
$data = [
  [
    'id' => 1,
    'Name' => "Mobile Game",
    'CategoryName' => "Mobile Legend"
  ],
  [
    'id' => 2,
    'Name' => "Laptop Game",
    'CategoryName' => "Mobile"
  ],
  [
    'id' => 3,
    'Name' => "Something",
    'CategoryName' => "Console"
  ]
];
$output = [];
foreach ($searchTerms as $searchTerm) {

  $pattern = sprintf('/%s/i', preg_quote($searchTerm));

  array_walk($data, function($entry, $index) use ($pattern, &$output) {
    if (!array_key_exists($index, $output)
      && (preg_match($pattern, $entry['Name'])
        || preg_match($pattern, $entry['CategoryName']))) {
      $output[$index] = $entry;
    }
  });

}

print_r($output);

The obvious output is: 

Array
(
    [0] => Array
        (
            [id] => 1
            [Name] => Mobile Game
            [CategoryName] => Mobile Legend
        )
    [1] => Array
        (
            [id] => 2
            [Name] => Laptop Game
            [CategoryName] => Mobile
        )
)
