curl post报错问题

curl_setopt() expects parameter 2 to be long 是什么错误？？

//初始化curl       	$ch = curl_init();		//设置超时		curl_setopt($ch, CURLOP_TIMEOUT, $this->curl_timeout);		curl_setopt($ch, CURLOPT_URL, $url);        curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);        curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,FALSE);		curl_setopt($ch, CURLOPT_HEADER, FALSE);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);		//运行curl，结果以jason形式返回        $res = curl_exec($ch);		curl_close($ch);

回复讨论(解决方案)

哪行报错？？

curl_setopt($ch, CURLOP_TIMEOUT, $this->curl_timeout);
改成
curl_setopt($ch, CURLO P_TIMEOUT, $this->curl_timeout);

看错了，改成这样
curl_setopt($ch, CURLOP T_TIMEOUT, $this->curl_timeout);
