PHP - strpos doesn't work correctly for me?

Question

So I am trying to search through JSON, using strpos for it, but it doesn't for me. I always get that "Items doesn't exist".

Here's the PHP

$getItems = file_get_contents('Items.json');
$decodeItems = json_decode($getItems,true);

//$output = ''.$decodeItems['items'][0]['name'].'';
$output = '';

if(isset($_POST['search'])){
    $searchq = $_POST['search'];
    $searchq = preg_replace("#[^0-9a-z]#i","",$searchq);

    foreach($decodeItems['items'] as $data){
        if($chance = strpos($data, $searchq) !== FALSE){
            if($data['name'] == $chance){
                $name = $data['name'];
                $output .= "<div>".$name."</div>";
            }
        }
        else{
            $output = 'Items no';
        }
    }
}

Here's the Example JSON

{"img":"-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXU5A1PIYQh5hlcX0nvUOGsx8DdQBJjIAVHubSaIAlp1fb3YihQ-tWglYy0lfjjOr6fxjpQ7MFz373Fodyl0AXh-ENkMWinJ4eXcA8-ZFHUq1K_xum70ZO56oOJlyUgjHI5fA","name":"&#x2605 Bowie Knife","assetid":"6442574944","myprice":"155.36","condition":"","originalname":"\u2605 Bowie Knife","inspect":"steam:\/\/rungame\/730\/76561202255233023\/+csgo_econ_action_preview%20S76561198034643020A6442574944D2305887113904442996","special":"0","floatvalue":null,"bitskinsprice":"117.36"}

Answer 1

From the manual the return value of strpos :

Returns the position of where the needle exists relative to the beginning of the haystack string (independent of offset). Also note that string positions start at 0, and not 1.

Returns FALSE if the needle was not found.

So, I suggest you to change this part of your code:

if(strpos($data['name'], $searchq) === true)

to

if(strpos($data['name'], $searchq) !== FALSE)

The JSON needs to follow the following notation in order for the code above to work:

{"items":[
   {
      "img":"img1",
      "name":"name1",
      "assetid":"1",
      "myprice":"155.36",
      "condition":"",
      "originalname":"name1 original",
      "inspect":"whatever",
      "special":"0",
      "floatvalue":null,
      "bitskinsprice":"117.36"
   },
   {
      "img":"img2",
      "name":"name2",
      "assetid":"2",
      "myprice":"175.11",
      "condition":"",
      "originalname":"name2 original",
      "inspect":"whatever2",
      "special":"0",
      "floatvalue":null,
      "bitskinsprice":"55.55"
   }
]};

OK, I made some changes to your script to deal correctly with the JSON file.

$getItems = file_get_contents('Items.json');
$decodeItems = json_decode($getItems,true);

//$output = ''.$decodeItems['items'][0]['name'].'';
$output = '';

if(isset($_POST['search'])){
    $searchq = $_POST['search'];
    $searchq = preg_replace("#[^0-9a-z]#i","",$searchq);

    foreach($decodeItems['items'] as $data){
       // this was *if($chance = strpos($data, $searchq) !== FALSE){*
       if(strpos($data['name'], $searchq) !== FALSE) {
          // here was another unneeded *if($data['name'] == $chance){*
          $name = $data['name'];
          $output .= "<div>".$name."</div>";
       }
    }

    if (empty($output)) {
      $output = 'Items no';
    }
}
