@H_404_0@FTP上传是PHP实现的一个常见且非常重要的应用技巧，今天就来与大家分享一下PHP实现FTP上传文件的简单示例。希望对大家的能带来一定的帮助。

@H_404_0@主要代码如下：

<div class="jb51code">
<pre class="brush:php;">
function make_directory($ftp_stream,$dir){
// if directory already exists or can be immediately created return true
if ($this->ftp_is_dir($ftp_stream,$dir) || @ftp_mkdir($ftp_stream,$dir)) return true;
// otherwise recursively try to make the directory
if (!$this->make_directory($ftp_stream,dirname($dir))) return false;
// final step to create the directory
return ftp_mkdir($ftp_stream,$dir);
}

function ftp_is_dir($ftp_stream,$dir){
// get current directory
$original_directory = ftp_pwd($ftp_stream);
// test if you can change directory to $dir
// suppress errors in case $dir is not a file or not a directory
if ( @ftp_chdir( $ftp_stream,$dir ) ) {
// If it is a directory,then change the directory back to the original directory
ftp_chdir( $ftp_stream,$original_directory );
return true;
} else {
return false;
}
}

$conn = ftp_connect("ftp地址") or die("Could not connect");
ftp_login($conn,"ftpname","password");
//利用ftp创建目录
make_directory($conn,$path);
//利用ftp选择进入目录
ftp_chdir($conn,$path);
//开始上传
if(ftp_put($conn,$info[0]['savename'],getcwd().$upload->savePath.$info[0]['savename'],FTP_BINARY)){
unlink(getcwd().$upload->savePath.$info[0]['savename']);
}
ftp_close($conn);
//注意上传端的ftp权限设置
