PHP partial strings in array to match string

I am building small application which has an input for a string. I also have an array of words and I want to match if any full value in the array matches partially with the input string. Example:

Array('London Airport', 'Mancunian fields', 'Disneyland Florida')

If a user types 'Disneyland Florida in USA' or just 'Disneyland Florida, USA' I want to return a match.

Any help would be highly appreciated. Thanks in advance.

Data to search in:

<?php
$data = array(
    0 => 'London Airport', 
    1 => 'Mancunian fields', 
    2 => 'Disneyland Florida'
);

Find full string

Searching function:

<?php
/**
 * @param array $data
 * @param string $what
 * @return bool|string
 */
function searchIn($data, $what) {
    foreach ($data as $row) {
        if (strstr($what, $row)) {
            return $row;
        }
    }

    return false;
}

Results:

<?php
// Disney Florida
echo searchIn($data, 'Disneyland Florida in USA');

// Disney Florida
echo searchIn($data, 'Disneyland Florida, USA');

// false
echo searchIn($data, 'whatever Florida Disneyland');
echo searchIn($data, 'No match');
echo searchIn($data, 'London');

Find by any combination of words

Searching function:

<?php
/**
 * @param array $data
 * @param string $what
 * @return int
 */
function searchIn($data, $what) {
    $needles = explode(' ', preg_replace('/[^A-Za-z0-9 ]/', '', $what));

    foreach ($data as $row) {
        $result = false;

        foreach ($needles as $needle) {
            $stack = explode(' ', $row);

            if (!in_array($needle, $stack)) {
                continue;
            }

            $result = $row;
        }

        if ($result !== false) {
            return $result;
        }
    }

    return false;
}

Results:

<?php
// Disneyland Florida
echo searchIn($data, 'Disneyland Florida in USA');

// Disneyland Florida
echo searchIn($data, 'Disneyland Florida, USA');

// Disneyland Florida
echo searchIn($data, 'whatever Florida Disneyland');

// false
echo searchIn($data, 'No match');

// London Airport
echo searchIn($data, 'London');

As you can see, id doesn't matter in what order user is searching and whether or not the string starts with Disneyland.

PHP 5.3+ for the use of the anonymous function:

<?php

$places = array('London Airport', 'Mancunian fields', 'Disneyland Florida');
$search = 'Disneyland Florida in USA';

$matches = array_filter($places, function ($place) use ($search) {
    return stripos($search, $place) !== false;
});

var_dump($matches);

function isInExpectedPlace($inputPlace) {
    $places = array('London Airport', 'Mancunian fields', 'Disneyland Florida');
    foreach($places as $place) {
        if(strpos($inputPlace, $place) !== false)
            return true;
        }
    }
    return false;
}
