What happened

Code for using variables

<?php
echo '111';
{
    try {
      $client = new Redis();
      $host = "127.0.0.1";
      $port = "6379";
      $client->connect($host, $port, 1);
      $client->set('foo', '1111');
    } catch (RedisException $e) {
    }
}
echo "ok";

Code for Unused Variables

<?php

echo '111';

{
        $client = new Redis();
        $client->connect("127.0.0.1", 6379, 1);
        $client->set('foo', '1111');
}

echo "ok";

Because the $port is string, skywalking agent except it to int failed, I will adapt this case.
