php array return distinct multidimensional array code example

Example 1: array_unique multidimensional php

<?php
    function super_unique($array,$key)
    {
       $temp_array = [];
       foreach ($array as &$v) {
           if (!isset($temp_array[$v[$key]]))
           $temp_array[$v[$key]] =& $v;
       }
       $array = array_values($temp_array);
       return $array;

    }


$arr="";
$arr[0]['id']=0;
$arr[0]['titel']="ABC";
$arr[1]['id']=1;
$arr[1]['titel']="DEF";
$arr[2]['id']=2;
$arr[2]['titel']="ABC";

Example 2: php search multidimensional array for multiple values

/**
   * PHP Search an Array for multiple key / value pairs
   */

  function multi_array_search($array, $search) {
    // Create the result array
    $result = array();

    // Iterate over each array element
    foreach ($array as $key => $value){

      // Iterate over each search condition
      foreach ($search as $k => $v){

        // If the array element does not meet the search condition then continue to the next element
        if (!isset($value[$k]) || $value[$k] != $v){
          continue 2;
        }
      }
      // Add the array element's key to the result array
      $result[] = $key;
    }

    // Return the result array
    return $result;
  }

  // Output the result
  print_r(multi_array_search($list_of_phones, array()));

  // Array ( [0] => 0 [1] => 1 )

  // Output the result
  print_r(multi_array_search($list_of_phones, array('Manufacturer' => 'Apple')));

  // Array ( [0] => 0 )

  // Output the result
  print_r(multi_array_search($list_of_phones, array('Manufacturer' => 'Apple', 'Model' => 'iPhone 6')));
