php linux curl_exec() 微信,該如何解決

php linux curl_exec()
function api_notice_increment($url, $data){
$ch = curl_init();
$header = "Accept-Charset: utf-8";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo "start";
$tmpInfo = curl_exec($ch);
echo $tmpInfo;
echo "end";
$errorno=curl_errno($ch);
if ($errorno) {
return array('rt'=>false,'errorno'=>$errorno);
}else{
$js=json_decode($tmpInfo,1);
if ($js['errcode']=='0'){
return array('rt'=>true,'errorno'=>0);
}else {
$errmsg=GetErrorMsg::wx_error_msg($js['errcode']);
$this->error($js['errcode'].':'.$errmsg.'!!');
}
}
}

在window上沒有任何問題，但是在linux系統上$tmpInfo返回為空白，curl的版本之前是4.4 現在換成了7.44 還是不行，請教一下，這個是什麼問題，困擾很久了
