微信支付常见问题一：CURLOP_TIMEOUT和curl_close()报错
刚下载的PHP版的"微信帐号支付DEMO"配置好“WxPay.pub.config.php”里的所有参数，调试时却发现报一大堆错误:
Notice: Use of undefined constant CURLOP_TIMEOUT - assumed 'CURLOP_TIMEOUT' in /www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php on line 821 Warning: curl_setopt() expects parameter 2 to be long, string given in /www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php on line 821 Notice: Use of undefined constant CURLOP_TIMEOUT - assumed 'CURLOP_TIMEOUT' in /www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php on line 155 Warning: curl_setopt() expects parameter 2 to be long, string given in /www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php on line 155 Warning: curl_close(): 6 is not a valid cURL handle resource in /www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php on line 175
检查再三，发现如上的三个问题其实完全是微信团队马虎所致
问题一：Notice: Use of
undefined constant CURLOP_TIMEOUT - assumed 'CURLOP_TIMEOUT' in
/www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php
on line 821 Warning: curl_setopt() expects parameter 2 to be long,
string given in
/www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php
on line 821
找到WxPayPubHelper.php文件的821行
curl_setopt($ch, CURLOP_TIMEOUT, $this->curl_timeout);
将其改成：
curl_setopt($ch, CURLOPT_TIMEOUT, $this->curl_timeout);
原因："CURLOPT_TIMEOUT"少写了一个"T"
问
题二：Notice: Use of undefined constant CURLOP_TIMEOUT - assumed
'CURLOP_TIMEOUT' in
/www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php
on line 155 Warning: curl_setopt() expects parameter 2 to be long,
string given in
/www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php
on line 155
找到WxPayPubHelper.php文件的155行
curl_setopt($ch, CURLOP_TIMEOUT, $second);
将其改成：
curl_setopt($ch, CURLOPT_TIMEOUT, $second);
原因：一样是少写了一个"T"
问
题三：Warning: curl_close(): 6 is not a valid cURL handle resource in
/www/web/other/freyun/public_html/pay/cs/WxPayPubHelper/WxPayPubHelper.php
on line 175
将注释“返回结果”前面的那一行注释起来即可
$data = curl_exec($ch);
//curl_close($ch);
//返回结果
if($data)
原因：在注释“返回结果”前面的那一行，已经将$ch连接关闭了，后面的if..else语句中又对它进行了关闭操作，很明显，第二次调用的时候这个连接已经不存在了，肯定会报错。
