php通过curl方式实现发送接收xml数据

<?php
function sendXmlData($url, $xmlData) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlData);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}
// 使用示例
$xmlData = '<root><name>John</name><age>25</age></root>';
$url = 'http://localhost/test22.php';
$response = sendXmlData($url, $xmlData);
// 处理响应
echo $response;

<?php
 
function receiveXmlData() {
    $xmlData = file_get_contents('php://input');
    // 解析XML数据
    $xml = simplexml_load_string($xmlData);
    // 处理XML数据
    // 例如，获取根元素的值
    $name = $xml->name;
    $age = $xml->age;
    // 返回处理结果
    $response = "Received XML Data:\nName: $name\nAge: $age";
    return $response;
}
// 使用示例
$response = receiveXmlData();
echo $response;

<?PHP
$xml_data = '<xml>xml</xml>';//发送的xml
$url = 'http://localhost/xml/getXML.php';//接收XML地址
$header[] = "Content-type: text/xml";//定义content-type为xml
$ch = curl_init(); //初始化curl
curl_setopt($ch, CURLOPT_URL, $url);//设置链接
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//设置是否返回信息
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);//设置HTTP头
curl_setopt($ch, CURLOPT_POST, 1);//设置为POST方式
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data);//POST数据
curl_setopt($ch, CURLOPT_TIMEOUT, 10); //设置超时时间为10
$response = curl_exec($ch);//接收返回信息
if(curl_errno($ch)){//出错则显示错误信息
print curl_error($ch);
}
curl_close($ch); //关闭curl链接
echo $response;//显示返回信息

<?php
$xml = file_get_contents('php://input');//监听是否有数据传入
if($xml!=''){//如果有数据传入，则将传入的数据写入到xml.txt文件
$fp = fopen('xml.txt','w');
fwrite($fp,$xml);
fclose($fp);
exit('OK');//写入成功后返回成功信息
}
die('Fail');//没有数据则直接返回失败信息

function sendRequest($requestXML)
{
$server = 'http://www.something.com/myapp';
$headers = array(
"Content-type: text/xml"
,"Content-length: ".strlen($requestXML)
,"Connection: close"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $server);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $requestXML);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$data = curl_exec($ch);
if(curl_errno($ch)){
print curl_error($ch);
echo "  something went wrong..... try later";
}else{
curl_close($ch);
