显示“1”的 cURL 和 PHP
我有一个PHP脚本，我想用它来从数据库中读取服务器并使用cURL连接到它们。服务器使用 sql 查询的结果进行响应。问题是，每次从服务器响应后，脚本都会显示数字 1。输出如下所示：
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
下面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1与“echo $result”一起显示，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;
$space = " ";
while ($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);
?>
请帮帮我
