Using an array as needles in strpos

@Dave an updated snippet from http://www.php.net/manual/en/function.strpos.php#107351

function strposa($haystack, $needles=array(), $offset=0) {
        $chr = array();
        foreach($needles as $needle) {
                $res = strpos($haystack, $needle, $offset);
                if ($res !== false) $chr[$needle] = $res;
        }
        if(empty($chr)) return false;
        return min($chr);
}

How to use:

$string = 'Whis string contains word "cheese" and "tea".';
$array  = array('burger', 'melon', 'cheese', 'milk');

if (strposa($string, $array, 1)) {
    echo 'true';
} else {
    echo 'false';
}

will return true, because of array "cheese".

Update: Improved code with stop when the first of the needles is found:

function strposa(string $haystack, array $needles, int $offset = 0): bool 
{
    foreach($needles as $needle) {
        if(strpos($haystack, $needle, $offset) !== false) {
            return true; // stop on first true result
        }
    }

    return false;
}
$string = 'This string contains word "cheese" and "tea".';
$array  = ['burger', 'melon', 'cheese', 'milk'];
var_dump(strposa($string, $array)); // will return true, since "cheese" has been found
