json - PHP Str_replace is not working in foreach loop -

here code.

i trying inspect link steam item. have tried use preg_replace no luck either.

    $api_link =     sprintf("http://steamcommunity.com/id/*steamid*/inventory/json/730/2?trading=1");     $json = file_get_contents($api_link);     $json_output = json_decode($json);     $result = $json_output;     $link = array();     $id = array();     foreach($result->rgdescriptions $item){       $empty = array();        $newstring = $item->actions[0]->link;     if($newstring == null){         continue;     } else {     $empty['link'] = $newstring;      array_push($link, $empty);     }            }            foreach($result->rginventory $inventory){          $empty = array();         if($inventory->instanceid == 0){             continue;         } else {             $empty['id'] = $inventory->id;             array_push($id, $empty);                 }     }      $array = array_merge($id, $link);      foreach($array $final){          $assetid = "%assetid%";          echo str_replace($assetid, $final['id'], $final['link']);      } 

}

but not working. please see if can help.

as can see have array of arrays:

// bracket squares equivalent of array() keyword php >=v5.4 // here // $link = array(['link'=>'url'],['link'=>'url']) // $id   = array(['id'=>'id'],['id'=>'id'])  // result be: //   array(['link']=>'url'],['link'=>'url'],['id'=>'id'],['id'=>'id']) $array = array_merge($id, $link);  foreach($array $final){     // here first $final     // array('link'=>'url')      $assetid = "%assetid%";      // here try     // 'id' , 'link'     echo str_replace($assetid, $final['id'], $final['link']); } 

i think it's kind of mistake.

ok, test script:

<?php  $a = array( array('link'=>'hello1'), array('link'=>'hello2')); $b = array( array('id'=>'id0'), array('id'=>'id1')); $c = array_merge($a, $b); var_dump($c); 

result:

array(4) {   [0] =>   array(1) {     'link' =>     string(6) "hello1"   }   [1] =>   array(1) {     'link' =>     string(6) "hello2"   }   [2] =>   array(1) {     'id' =>     string(3) "id0"   }   [3] =>   array(1) {     'id' =>     string(3) "id1"   } } 

array_merge doesn't mix associative arrays between them nether nor particular item (i hope explain correct)

of course

foreach ($c $item) {   var_dump($item); } 

will enumerate items 1 one

  array(1) {     'link' =>     string(6) "hello1"   }    array(1) {     'link' =>     string(6) "hello2"   }    array(1) {     'id' =>     string(3) "id0"   }    array(1) {     'id' =>     string(3) "id1"   } 

and there no array has both of them (link , id) in item

this script can't associate link , id properly, cause of links can skipped continue, of id can skipped. , random list of available information. can stuck in next situation:

 - $links has first 10 links  - $id has 3,4,5,7,9,11 

it's list. if have only pure info (no other details), can't associate between of them using shown source.

here minimum 1 simple solutions:

don't skip, don't merge, add empty array, , final loop this:

$assetid = "%assetid%"; ($link $key=>$final) {   if (count($final) && count($id[$key])) {     echo str_replace($assetid, $id[$key]['id'], $final['link']);   } else {      // of needed arguments absent   } }
