尽管使用了error_reporting(0），仍然会得到Json解析错误

我使用php 5.5，由于Logcat消息，我收到Json Parser错误：

 <br />
 <b>Deprecated</b>:  mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in <b>/home4/enippeas/public_html/select_itin2.php</b> on line <b>2</b><br />

我发现我必须转到pdo（注意，我的应用程序仅用于教育目的），但为了避免收到错误，我尝试使用

error_reporting(0);

但我还是犯了同样的错误。任何想法；

php文件
