Answer 1

Verwenden preg_quote Funktion Sonderzeichen in einem String innerhalb RegexMuster verwendet zu entkommen:

$data = json_decode($json,true); 
$prices = $data['prices']; 

$item = 'AK-47 | Black Laminate (Factory New)'; 
foreach ($prices as $items){ 
    foreach ($items as $key => $value){ 
     if (preg_match("/". preg_quote($item) ."/i", $value)) { 
      echo $key."<br>"; 
      echo $value."<br>"; 
     } 
    } 
} 

Der Ausgang:

market_hash_name 
AK-47 | Black Laminate (Factory New)

Answer 2

Problem erkannt werden, ist in RegEx Muster, | und () sind Regex Characheter.

können Sie preg_quote verwenden

Versuchen

if (preg_match("/". preg_quote($item) ."/i", $value)) { 

statt

if(preg_match("/".$item."/i",$value)){ 

und auch können Sie versuchen, Ihre Regex ändern:

$item = 'AK-47 \| Black Laminate \(Factory New\)';
