php实现curl上传与下载以及https登陆的实例

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;
