我有一个PHP脚本，可以用来从数据库读取服务器并使用cURL连接到它们。服务器以sql查询的结果作为响应。问题是每个服务器响应后的脚本显示数字1。输出看起来像这样：

服务器1：一些结果

1服务器2：一些结果

1服务器3：一些结果

1个

这是从数据库读取服务器并连接到它们的代码：

<?php

$mysql_id = mysql_connect('localhost', 'ms', 'pass');
mysql_select_db('servers', $mysql_id);
mysql_query("SET NAMES utf8");

$query = "SELECT * FROM svr";
$result = mysql_query($query);
$num = mysql_num_rows($result);
while ($data = mysql_fetch_assoc($result))
{
    $server[] = $data;
}

mysql_close($mysql_id);

$i = 0;
while($i < $num) {
    $dealer = $server[$i]['dealer'];

    echo $dealer . "<br />";

    $data = "val=a"; //just for testing

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);    
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                                                                                                       
        'Content-Type: text/html; charset=utf-8')                                                                       
    );

    $result = curl_exec($ch);
    echo $result;
    $i++;
}

?>

我发现显示1时显示“ echo $ result;”。和用于创建响应的代码是这样的：

<?php

$mysql_id1 = mysql_connect('localhost', 'ms', 'pass');
mysql_select_db('servers', $mysql_id1);
mysql_query("SET NAMES utf8");

    $query2 = "SELECT * FROM data";
    $result2 = mysql_query($query2);
    $num2 = mysql_num_rows($result2);
    while ($data2 = mysql_fetch_assoc($result2))
    {
        $deli[] = $data2;
    }
    $i1 = 0;
    $space = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
    while ($i1 < $num2) {
        echo $space . $deli[$i1]['id'] . " ";
        echo $deli[$i1]['artikel'] . " ";
        echo $deli[$i1]['znamka'] . " ";
        echo $deli[$i1]['model'] . " ";
        echo $deli[$i1]['letnik'] . " ";
        echo $deli[$i1]['cena'] . " € ";
        echo $deli[$i1]['zaloga'] . "<br />";
        $i1++;
    }
    echo "<br />";
    mysql_close($mysql_id1);
?>

请帮我
