 $result = mysql_query("SELECT * FROM $tableName WHERE id=1");               
 $array = mysql_fetch_array($result); 
 $help_name = $array['name'];
 $req =   $array['req'];
 //fetch result    

 echo json_encode($help_name);

问题是我用双引号得到结果,如何删除双引号

有人可以帮我重置一个mysql计数器.这是代码

$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="members"; // Table name 

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect to server "); 
mysql_select_db("$db_name")or die("cannot select DB");

$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);

$rows=mysql_fetch_array($result);
$counter=$rows['counter'];

// if have no counter value set counter = 1
if(empty($counter)){
$counter=1;
$sql1="INSERT INTO $tbl_name(counter) VALUES('$counter')";
$result1=mysql_query($sql1);
}

echo "You 're visitors No. ";
echo $counter;

// count more value
$addcounter=$counter+1;



// reset …
