In_array but with more values

Example:

$array = array('hi', 'hello', 'bye');

How can I check if at least one of two or more values are present in the array ?

like:

if(in_array('hi', $array) || in_array('hello', $array)) ...

but with a single check? can it be done?

use array_intersect()... i.e.

$array = array('hi', 'hello', 'bye');
if(count(array_intersect($array, array('search', 'for', 'values')))>0) ....

Take a look at preg_grep, which will return entries in an array that match a predefined pattern (e.g. '/^(hi|hello)$/ in your example).

E.g.

if (count(preg_grep('^/(hi|hello)$/',$array)))
{
  // your code
}

function in_array2($ary1,$ary2){
  return count(array_intersect($ary1,$ary2)) > 0;
}

Simple, make use of array_intersect.
