Define multiple needles using stripos

Question

How can i define multiple needles and still perform the same actions below. Im trying to define extra keywords such as numbers, numerals, etc... as of now i have to create a duplicate if loop with the minor keyword change.

if (stripos($data, 'digits') !== false) {
$arr = explode('+', $data);

for ($i = 1; $i < count($arr); $i += 2) {
    $arr[$i] = preg_replace('/\d/', '', $arr[$i]);
}

$data = implode('+', $arr);
}

Answer 1

Create a function that loops through an array?

function check_matches ($data, $array_of_needles)
{
   foreach ($array_of_needles as $needle)
   {
        if (stripos($data, $needle)!==FALSE)
        {
             return true;
        }
   }

   return false;
}

if (check_matches($data, $array_of_needles))
{
   //do the rest of your stuff
}

--edit added semicolon

@Ben Stephenson The loops look correct to me, i am new to PHP but im getting syntax error, unexpected '}', any clue why? It's unclear to me. – Intraatomic

I've messed around with the loops but im afraid ill exclude something... If you have any ideas let me know. – Intraatomic

@Ryan/@Ben, you're just missing a semi-colon after the return true. – Peadar

@Peadar Thanks, i appreciate it i cant believe i missed that. I'm used to it throwing unexpected T_VARIABLE... now i know next time, thanks. – Intraatomic

Answer 2

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);
}

Usage:

$array  = array('1','2','3','etc');

if (strposa($data, $array)) {
  $arr = explode('+', $data);

  for ($i = 1; $i < count($arr); $i += 2) {
    $arr[$i] = preg_replace('/\d/', '', $arr[$i]);
  }

  $data = implode('+', $arr);

} else {
  echo 'false';
}

Answer 3

Though the previous answers are correct, but I'd like to add all the possible combinations, like you can pass the needle as array or string or integer.
To do that, you can use the following snippet.

function strposAll($haystack, $needles){
    if(!is_array($needle)) $needles = array($needles); // if the $needle is not an array, then put it in an array
    foreach($needles as $needle)
        if( strpos($haystack, $needle) !== False ) return true;
    return false;
}

You can now use the second parameter as array or string or integer, whatever you want.
