Question

I have an array named results_array:

var_dump($results_array):
0 => php,mysql,jquery,ruby,html,css,lamp
1 => mouse,keyboard,laptop,pad
2 => table,sofa,caption
3 => control,television,control television,television control

and I have a $q which stands for query, I want to search in the $results_array and remove the items which has nothing to do with the query, so if I set $q=a then results array should be this:

0 => lamp
1 => keyboard,laptop,pad
3 => table,sofa,caption
4 => empty

now, I want to put the above results in each index of the results_array, at the end results_array should be:

0 => lamp
1 => keyboard
2 => laptop
3 => pad
4 => table
5 => sofa
6 => caption

my code is:

foreach($results_array as &$row) {
            $row = explode(',', $row);
        }
        unset($row);
        $results_array = call_user_func_array('array_merge_recursive', $results_array);

        foreach ($array as $k => $v) {
            if(strpos($v, 'a') === false) unset($array[$k]);
        }
        $results_array = array_values($results_array);

this exactly does what I need, now I set my $q = ‘tele co’, now after applying the above code set $ = ‘tele co’, it returns emtpy, but it should not because in:

3 => control,television,control television,television control

‘control television,television control’ should returned, but it’s not, so I change my code to:

foreach($results_array as &$row) {
            $row = explode(',', $row);
        }
        unset($row);
        $results_array = call_user_func_array('array_merge_recursive', $results_array);
// HERE IS CHANGED ****
        $q = preg_split('/\s+/', trim($q));
        foreach ($results_array as $key => $value) {
            foreach ($q as $query) {
                if (stripos($value, $query) === false) {
                    unset($results_array[$key]);
                    break;
                }
            }
        }
// ****
        $results_array = array_values($results_array);

it’s still not working, by passing $q = ‘tele co’ I need that ‘television control’ and ‘control television’ return, because they both got ‘tele’ AND ‘co’ which is in $q

I appreciate any kind of help

Answer 1

Assuming:

$q = 'a c';
$results_array = array(
    'php,mysql,jquery,ruby,html,css,lamp',
    'mouse,keyboard,laptop,pad',
    'table,sofa,caption',
    'control,television,control television,television control'
);

Solution:

$result = array_map(function ($element) use ($q) {
    $words = explode(',', $element);
    return array_filter($words, function ($word) use ($q) {
        $qwords = explode(' ', $q);
        return count(array_filter($qwords, function ($qword) use ($word) {
            return strpos($word, $qword) !== false;
        })) > 0;
    });
}, $results_array);

Output print_r($result);:

Array
(
    [0] => Array
        (
            [5] => css
            [6] => lamp
        )

    [1] => Array
        (
            [1] => keyboard
            [2] => laptop
            [3] => pad
        )

    [2] => Array
        (
            [0] => table
            [1] => sofa
            [2] => caption
        )

    [3] => Array
        (
            [0] => control
            [2] => control television
            [3] => television control
        )
