cURL 是一个利用URL语法规定来传输文件和数据的工具，支持很多协议，如HTTP、FTP、TELNET等。最爽的是，PHP也支持 cURL 库。今天绵阳动力网络公司为大家来详细介绍关于php中curl库的上传、下载和https登陆的实现方法和代码：
1、curl下载
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "ftp://127.0.0.1/downtest.txt");
curl_setopt($ch, CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_TIMEOUT,300);
//设置用户名和密码
curl_setopt($ch, CURLOPT_USERPWD,"yuejide:123456");
$outfile = fopen("test.txt","wb");
curl_setopt($ch,CURL_FILE,$outfile);
$rtn = curl_exec($ch);
fclose($outfile);
if(!curl_errno($ch)){
echo $rtn;
}else{
echo 'curl error'.curl_errno($ch);
}
curl_close($ch);
2、curl上传
$ch = curl_init();
$localfile = "ftp01.php";
$fp = fopen($localfile,'r');
curl_setopt($ch, CURLOPT_URL, "ftp://127.0.0.1/ftp01_upload.php");
curl_setopt($ch, CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_TIMEOUT,300);
//设置用户名和密码
curl_setopt($ch, CURLOPT_USERPWD,"yuejide:123456");
curl_setopt($ch, CURLOPT_UPLOAD,1);
curl_setopt($ch, CURLOPT_INFILE,$fp);
curl_setopt($ch, CURLOPT_INFILESIZE,filesize($localfile));
$rtn = curl_exec($ch);
fclose($fp);
if(!curl_errno($ch)){
echo "upload successfully";
}else{
echo 'curl_error'.curl_error($ch);
}
curl_close($ch);
3、curl https登录
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.baidu.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
date_default_timezone_set('PRC');
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
