php array alike search

Question

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

if (in_array('hei',$array)) echo 'aaa';

This will not work, because there is no "hei" in the array, but I need something to search not with exact string.

In mySQL we have WHERE x ALIKE y. What can we use to find for alike string in array, not exact?

Thanks

You'd have to loop through the array checking each value with soundex() or levenshtein() or similar_text() to find similar words — Mark Baker

Use this function:

    function like_in_array( $sNeedle , $aHaystack )
    {

        foreach ($aHaystack as $sKey)
        {
            if( stripos( strtolower($sKey) , strtolower($sNeedle) ) !== false )
            {
                return true;
            }
        }

        return false;
    }

   if(like_in_array('hei', $array)) {
      echo 'in array';
   }
