Array_in_String

I just wrote this function :

function Array_in_String($Haystack1, $Values1)
{
    foreach ($Values1 as $token1) 
    {
        if (strpos($Haystack1, $token1) !== false) return true;
    }
}

that basically searches a string $Haystack1 for multiple values in an array $Values1 and returns true if hits a match.

Before that, I searched a lot in PHP for a similar string function. I'm still wondering if PHP has a similar function?

return array_reduce(
  $Values1,
  function($result, $token1) use ($Haystack1) {
    return $result || strpos($Haystack1, $token1) !== false;
  }, 
  false
);

or

$matches = array_map(
  function($token1) use ($Haystack1) {
    return strpos($Haystack1, $token1) !== false;
  },
  $Values1
);
return (bool) count(array_filter($matches));

I'm not aware of such a function, but your logic can be greatly simplified by using str_replace.

function array_in_string($haystack, $needles) {
    return str_replace($needles, '', $haystack) !== $haystack;
}

Fiddle

Though, if your needle array is really huge, the code posted in your question may have a better performance as it will return true in the first match while my solution always iterates over all needles.

No, PHP does not have the function you need.
EDIT
Create your custom function if you want to use some code more than once.

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);

this produces:

"lastname,email,phone"

Edit: of course you'll have to make a preg_match on this string afterwards.
