本文主要和大家分享PHP实现模拟微信公众号开发者模式，主要以代码的形式和大家分享，希望能帮助到大家。
$url = 'http://xxxx.com/test/aaaa/index.php';//开发者URL
$token = 'weixin';//TOKEN
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
$url .= stripos($url, '?') === false ? '?' : '&';
$url .= http_build_query(array(
'signature' => $tmpStr,
'timestamp' => $timestamp,
'nonce' => $nonce,
));
//echo $url;
//如果不是项目相关的事件 $returnStr返回空
$header = array();
//这个要加上啊
$header[] = "Content-type: text/xml";//定义content-type为xml
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postStr);
//curl_setopt($ch, CURLOPT_POSTFIELDS, $pp);
$response = curl_exec($ch);
if(curl_errno($ch)){
error_log (curl_error($ch));
}
curl_close($ch);
echo $response;//返回给微信服务器相关推荐：
