PHP curl空结果

Question

我有一个PHP脚本发送请求到网址。但结果是空的。

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLINFO_HEADER_OUT, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_AUTOREFERER, true); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_ENCODING , "gzip, deflate"); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/x-www-form-urlencoded', 
    'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp', 
    'Connection: Keep-Alive', 
    'User-Agent:Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.111 Safari/537.36' 
)); 
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
    'Format'=>'image/png', 
    'width'=>'550', 
    'height'=>'250', 
)); 
$reuslt = curl_exec($ch); 
$error_no = curl_errno($ch); 

curl_close($ch); 

我写echo $reuslt;但是这给错误是这样的：注意：未定义的变量：结果

我写echo $error;此写入结果0

这个查询结果应该PNG图像回到我浏览器，但什么都不修改。

Answer 1

它应该是$result无处不是$reuslt（或其他方式，但不是混合）
