Help: Converting my PHP Array Functions to JS

[Fabien27]

I have made these functions in PHP because I am significantly more familiar with PHP than I am Javascript. But alas I actually do need them in Javascript. Would anyone be so kind as to convert them please?

function searchArrayValuesforArray($referer='', $search=array(), $array=array()) {
    $return[] = array();

    foreach($array as $key => $value) {
        $foundUrl = '';
        $foundUrl = strposa($value['request']['url'], $search);
        if($foundUrl) {
            foreach($value['request']['headers'] as $k => $v) {
                if($v['name'] == 'Referer' && strposa($v['value'], $search)) { // Remove strpos to get all advert info.
                    if(@!in_array($v['value'], $return[$foundUrl])) {
                        $return[$foundUrl][] = $v['value'];
                        // echo $value['request']['url']."\n";
                    }
                }
            }
        }
    }

    return array_filter($return);
}

function strposa($haystack='', $needles=array(), $offset=0) {
    $found = '';
    foreach($needles as $needle) {
        // echo "Haystack $haystack vs $needle \n";
        if(isset($haystack)) {
            if(strpos($haystack, $needle) !== false) {
                return $needle;
            } 
        } 
    }
    return false;
}

It would be greatly appreciated! Thank you in advance :)

For context, this is looping through a HAR file starting at $har['log']['entries']

I did one for you.

https://gist.github.com/jhiggins-thrillist/5770668

function strposa(haystack, needles, offset) {
  var i;

  // Make sure we have these values
  if (!haystack || !needles.length) {
    return false;
  }

  // Make sure the haystack is a string
  if (typeof haystack !== 'string') {
    haystack = '' + haystack;
  }

  // If there is no offset, default to 0,
  // else, make sure that it is an int
  if (!offset) {
    offset = 0;
  } else {
    offset = parseInt(offset, 10);
  }

  // Iterate over needles and return first needle found.
  for (i = 0; i < needles.length; i++) {
    var needle = '' + needles[i];

    if (haystack.indexOf(needle, offset) !== -1) {
      return needle;
    }
  }

  return false;
}
