這是工作的罰款。嘗試這個https://eval.in/795253 –

嘗試設置你的腳本爲utf8：** mb_internal_encoding（'UTF-8'）; ** –

它工作正常，請再次檢查 – Faisal

嘗試使用json_last_error（）來獲取錯誤。

這樣子。

$json[] = "{'json': 'MyJson'}"; 

foreach ($json as $string) { 
    echo 'Decoding: ' . $string; 
    json_decode($string); 

    switch (json_last_error()) { 
     case JSON_ERROR_NONE: 
      echo ' - No errors'; 
     break; 
     case JSON_ERROR_DEPTH: 
      echo ' - Maximum stack depth exceeded'; 
     break; 
     case JSON_ERROR_STATE_MISMATCH: 
      echo ' - Underflow or the modes mismatch'; 
     break; 
     case JSON_ERROR_CTRL_CHAR: 
      echo ' - Unexpected control character found'; 
     break; 
     case JSON_ERROR_SYNTAX: 
      echo ' - Syntax error, malformed JSON'; 
     break; 
     case JSON_ERROR_UTF8: 
      echo ' - Malformed UTF-8 characters, possibly incorrectly encoded'; 
     break; 
     default: 
      echo ' - Unknown error'; 
     break; 
    } 

    echo PHP_EOL; 
}

你可以試試這個解決方法：

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; 

var_dump(json_decode($json)); 
var_dump(json_decode($json, true)); 

?>
