Question

这是我的代码：

$query = "SELECT first_name, surname, email FROM app2";
$result = mysql_query($query) or die(mysql_error());

 $url = "https://test.com?"; // Where you want to post data
 while($row = mysql_fetch_array($result)) {
        $input = "";
        foreach($row as $key => $value) $input .= $key . '=' . urlencode($value) . '&';
        $input = rtrim($input, '& ');

        $ch = curl_init();                    // Initiate cURL
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);  // Tell cURL you want to post something
        curl_setopt($ch, CURLOPT_POSTFIELDS, $input); // Define what you want to post
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the output in string format
        $output = curl_exec ($ch); // Execute

        curl_close ($ch); // Close cURL handle

        var_dump($output); // Show output
    }

问题是数据（$ input）出现如下：

0=Lucky&first_name=Lucky&1=Dube&surname=Dube

应该是这样的：

first_name=Lucky&surname=Dube

Answer 1

无需自行构建查询。首先，只需使用_assoc()*函数flavor，然后在该行数组批处理上使用http_build_query，然后将其提供。它将为您构造查询字符串。无需使用&附加foreach的每个元素。粗略的例子：

$url = "https://test.com"; // Where you want to post data

while($row = mysql_fetch_assoc($result)) {

    $input = http_build_query($row);
    $ch = curl_init(); // Initiate cURL
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);  // Tell cURL you want to post something
    curl_setopt($ch, CURLOPT_POSTFIELDS, $input); // Define what you want to post
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the output in string format
    $output = curl_exec ($ch); // Execute

    curl_close ($ch); // Close cURL handle
}

尝试更改

while($row = mysql_fetch_array($result)) {

与

while($row = mysql_fetch_assoc($result)) {

mysql_fetch_assoc仅返回关联数组。

清理数组
