Searching Multidimentional arrays to match keys of two arrays with Php

Question

Here are two example of the format of the Arrays, full code and array content in my code below.

ARRAY 1

Array
(
[version] => 1.0
[injuries] => Array
(
[timestamp] => 1377702112
[week] => 1
[injury] => Array
(
[0] => Array
(
[status] => Questionable
[id] => 10009
[details] => Shoulder

)

[1] => Array
(
[status] => Questionable
[id] => 10012
[details] => Ankle

)

ARRAY 2

Array
(
[version] => 1.0
[players] => Array
(
[timestamp] => 1377676937
[player] => Array
(
[0] => Array
(
[position] => TMDL
[name] => Bills, Buffalo
[id] => 0251
[team] => BUF
)

[1] => Array
(
[position] => TMDL
[name] => Colts, Indianapolis
[id] => 10009
[team] => IND
)

What I need to do is sort through both Arrays and finding matching values for the ID key. I need to then combine the values of both arrays into one array so I can print it out on screen. There is two API's provided, one for the injuries report with a player [id] key and the other for the Players Information with [id] keys. Here is how far I have gotten on this problem:

<?php

       function injuries_report() {         

       //Get json files

         $injuryData = file_get_contents('http://football.myfa...=1&callback=');
         $playerData = file_get_contents('http://football.myfa...L=&W=&JSON=1');

       //format json data into an array

          $obj1 = json_decode($injuryData, true);
         $obj2 = json_decode($playerData, true);



         //return print_r($obj1);   //print obj1 to see output

         return print_r($obj2);     //print obj2 to see output

       }

      ?> 

       <!--get injuries report -->

      <pre><?php injuries_report(); ?></pre>

Here's the working code, thanks to Chris:)

$injuryData = file_get_contents('http://football.myfantasyleague.com/2013/export?TYPE=injuries&L=&W=&JSON=1&callback=');
    $array1 = json_decode($injuryData, true);
    $playerData = file_get_contents('http://football.myfantasyleague.com/2013/export?TYPE=players&L=&W=&JSON=1');
    $array2 = json_decode($playerData, true);

    function map($x) {
       global $array1;
       if(isset($x['id'])) {
          $id = $x['id'];
          $valid = array_filter($array1['injuries']['injury'], create_function('$injury', 'return $injury["id"] == "' . $id .'";'));
          if(count($valid) > 0) {
             $x = array_merge($x, array_shift($valid));
          }
           }
           return $x;
        }
        $output = array_map('map', $array2['players']['player']);
        echo "<pre>";
        print_r($output);
        echo "</pre>";

Answer 1

Ok, I'm assuming you want to add injuries to players. The output will be the list of players, with the injuries added (where they apply)

$output = array_map(function($x) use ($array1) {
   $id = $x['id'];
   $valid = array_filter($array1['injuries']['injury'], function($injury) use ($id) {
      return $injury['id'] == $id;
   });
   if(count($valid) > 0) {
      $x = array_merge($x, $valid[0]);
   }
   return $x;
}, $array2['players']['player']);

print_r($output);

The output is this:

Array
(
    [0] => Array
        (
            [position] => TMDL
            [name] => Bills, Buffalo
            [id] => 0251
            [team] => BUF
        )

    [1] => Array
        (
            [position] => TMDL
            [name] => Colts, Indianapolis
            [id] => 10009
            [team] => IND
            [status] => Questionable
            [details] => Shoulder
        )
)

php 5.2

Edit The latest working version:

Oh you are using php 5.2. Here is a php 5.2 version, but it less pretty than the code before:

$injuryData = file_get_contents('http://football.myfantasyleague.com/2013/export?TYPE=injuries&L=&W=&JSON=1&callback=');
$array1 = json_decode($injuryData, true);
$playerData = file_get_contents('http://football.myfantasyleague.com/2013/export?TYPE=players&L=&W=&JSON=1');
$array2 = json_decode($playerData, true);

function map($x) {
   global $array1;
   if(isset($x['id'])) {
      $id = $x['id'];
      $valid = array_filter($array1['injuries']['injury'], create_function('$injury', 'return $injury["id"] == "' . $id .'";'));
      if(count($valid) > 0) {
         $x = array_merge($x, array_shift($valid));
      }
   }
   return $x;
}
$output = array_map('map', $array2['players']['player']);
print_r($output);

The $array1 is global here. Check it here: http://pastebin.com/N3RqtfzN
