A simple preg_grep will do the job:

$arr = array(
    'Canon sample printing text',
    'Captain text',
    'Canon EOS Kiss X4 (550D / Rebel T2i) + Double Zoom Lens Kit',
    'Fresh sample Roasted Seaweed',
    'Fresh sample text Seaweed'
);
$matched = preg_grep('~(sample|text)~i', $arr);
print_r($matched);

OUTPUT:

Array
(
    [0] => Canon sample printing text
    [1] => Captain text
    [3] => Fresh sample Roasted Seaweed
    [4] => Fresh sample text Seaweed
)

what does ~i means in preg_grep()?

anubhava Over a year ago

i is for ignore case and ~ is regex delimiter here.

preg_grep does the trick:

$input = preg_quote('bl', '~'); // don't forget to quote input string!
$data = array('orange', 'blue', 'green', 'red', 'pink', 'brown', 'black');

$result = preg_grep('~' . $input . '~', $data);

hope this will sure work for you.
