array_unique with two arrays

Question

I have two arrays of the same length ($search_type, $search_term). I want to remove any duplicates in the sense of there being searches that have the same type and

Answer 1

Ok, here's an overly complex ad-hoc function foo() (lacking error handling, documentation and testing) that combines those two arrays. array_unique() takes care of the duplicates.

'termC', 'bar'=>'termD', 'termB', 'termA');
$search_type= array('typeA', 'typeB', 'foo'=>'typeC', 'bar'=>'typeD', 'typeB', 'typeA');

$x = foo(array('term', $search_term), array('type', $search_type));
$x = array_unique($x, SORT_REGULAR);
var_dump($x);

function foo() {
  $rv = array();
  $params = func_get_args();
  foreach ( array_keys($params[0][1]) as $key ) {
    $rv[$key] = array();  
    foreach( $params as $p ) {
      $rv[$key][$p[0]] = $p[1][$key];  
    }
  }
  return $rv;
}

prints

array(4) {
  [0]=>
  array(2) {
    ["term"]=>
    string(5) "termA"
    ["type"]=>
    string(5) "typeA"
  }
  [1]=>
  array(2) {
    ["term"]=>
    string(5) "termB"
    ["type"]=>
    string(5) "typeB"
  }
  ["foo"]=>
  array(2) {
    ["term"]=>
    string(5) "termC"
    ["type"]=>
    string(5) "typeC"
  }
  ["bar"]=>
  array(2) {
    ["term"]=>
    string(5) "termD"
    ["type"]=>
    string(5) "typeD"
  }
}
