php把文件上传到远程服务器上例子
在这里我们利用curl实现把本地服务器的文件通过curl发送请求给远程服务器的php文件接受就实现了上传,还一个是利用ftp来上传方法也是php中的curl操作ftp服务器进行上传.
我这里写的是用curl的代码,本地代码如下:
<?php
header( 'content-type:text/html;charset=utf8' );
$curl = curl_init();
$data = array ( 'img' => '@' . dirname( __FILE__ ). '/img/login.gif' );
curl_setopt( $curl , CURLOPT_URL, "http://www.demo.com/uploadimg.php" );
curl_setopt( $curl , CURLOPT_RETURNTRANSFER, true);
curl_setopt( $curl , CURLOPT_POST, true);
curl_setopt( $curl , CURLOPT_POSTFIELDS, $data );
$result = curl_exec( $curl );
curl_close( $curl );
echo json_decode( $result );
?>远程服务器接受端代码,代码如下:
<?php
if ( $_FILES )
{
$filename = $_FILES [ 'img' ][ 'name' ];
$tmpname = $_FILES [ 'img' ][ 'tmp_name' ];
if (move_uploaded_file( $tmpname , dirname( __FILE__ ). '/img/' . $filename ))
{
echo json_encode( '上传成功' );
}
else
{
$data = json_encode( $_FILES );
echo $data ;
}
}
?>例子,同样是利用curl不过这是利用ftp,代码如下:
<?php
$localfile = "php_homepage.txt" ;
$fp = fopen ( $localfile , "r" );
$arr_ip = gethostbyname (www.phpfensi.com);
echo $arr_ip ;
$ftp = "ftp://" . $arr_ip . "/public_html/" . $localfile ;
$ch = curl_init();
curl_setopt( $ch , CURLOPT_VERBOSE, 1);
curl_setopt( $ch , CURLOPT_USERPWD, '***:****' );
curl_setopt( $ch , CURLOPT_URL, $ftp );
curl_setopt( $ch , CURLOPT_PUT, 1);
curl_setopt( $ch , CURLOPT_RETURNTRANSFER, 1);
curl_setopt( $ch , CURLOPT_INFILE, $fp );
curl_setopt( $ch , CURLOPT_INFILESIZE, filesize ( $localfile ));
$http_result = curl_exec( $ch );
$error = curl_error( $ch );
echo $error . "<br>" ;
$http_code = curl_getinfo( $ch ,CURLINFO_HTTP_CODE);curl_close( $ch );
fclose( $fp );
?>
