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