[php代码]从svn获取指定版本，并同步到ftp上。

1.从svn获取指定版本。

命令行：svn update  svnworkpath --username xxx --password xxx -r head

$cmd = "svn update..."
$ar = array();   
$status = 0;   
exec($cmd, $ar, $status); 

返回的结果包含以下内容：

A    002/ftp_upload.php
U    002/main.php
D    002/config.php

2.处理成本地路径和服务器上传路径：

function svnMessage($remoteArr,$localArr,$CONFIG_PG,$CONFIG_DIR)   
{   
/*  
* local dir  
*/   
for($ctr = 0;$ctr < count($localArr)-1; $ctr++)   
{   
//$localArr[$ctr] = str_replace ($CONFIG_FLG,'',$localArr[$ctr]);   
$istr = stripos($localArr[$ctr], $CONFIG_PG);   
$localArr[$ctr] = substr($localArr[$ctr],$istr);   
$localArr[$ctr] = str_replace ('\\','/',$localArr[$ctr]);   
}   
echo "本地路径:<br />\r\n";   
for($ctr = 0;$ctr < count($localArr)-1; $ctr++)   
{   
echo $localArr[$ctr];   
echo "<br />\r\n";
}   
  
/*  
* remote dir  
*/   
for($i = 0;$i < count($remoteArr)-1; $i++)   
{   
//$remoteArr[$i] = str_replace ($CONFIG_PG,'',$remoteArr[$i]);   
$imstr = stripos($remoteArr[$i], $CONFIG_PG);   
$remoteArr[$i] = substr($remoteArr[$i],$imstr+strlen($CONFIG_PG));   
$remoteArr[$i] = $CONFIG_DIR.str_replace ('\\','/',$remoteArr[$i]);   
}   
echo "<br />\r\n上传路径:<br />\r\n";   
for($i = 0;$i < count($remoteArr)-1; $i++)   
{   
echo $remoteArr[$i];   
echo "<br />\r\n";   
}   
} 

3.连接到ftp

$conn = ftp_connect($ftp_ip) or die("Could not connect");   
ftp_login($conn,$ftp_user,$ftp_pass);  

4.上传时区分A,U,D和文件或文件夹

function ftp_handle_one($conn,$aud,$localfile,$remotefile)
{
	echo "$aud,$localfile,$remotefile\r\n";
	$r= true;
	if($aud == 'D'){
		//删除时，找不到本地文件，无法判断是否文件夹。
		try{
			$r = ftp_delete($conn,$remotefile);
			echo "删除文件 $remotefile --> $r\r\n";
			if(!$r){
				$r = removeDir($conn,$remotefile);
				echo "删除目录 $remotefile --> $r\r\n";
			}
		}catch(Exception $e){
			echo '捕获异常: ' . $e->getmessage() . "<br/>错误代码：" . $e->getcode().'<br/>\r\n';
			echo "------\r\n";
		}
	}else if($aud == 'A'){
		if(is_dir($localfile)){
			$r = ftp_mkdir($conn,$remotefile);
			echo "创建目录 $remotefile --> $r\r\n";
		}else{
			$r = ftp_upload_one($conn,$localfile,$remotefile);
			echo "创建文件 $remotefile --> $r\r\n";
		}
	}else if($aud == 'U'){
		if(is_dir($localfile)){
			//ftp_rmdir($conn,$remotefile);
		}else{
			$r = ftp_upload_one($conn,$localfile,$remotefile);
			echo "更新文件 $remotefile --> $r\r\n";
		}
	}
}

5.递归删除一个目录

function removeDir($conn, $dirName )
{
   $arr = ftp_rawlist($conn,$dirName);
   //是个目录时，默认会有三行
   //array(3) {
//  [0]=>string(7) "total 0"
//  [1]=>string(56) "drw-rw-rw-   1 user     group           0 Sep 23 13:56 ."
//  [2]=>string(57) "drw-rw-rw-   1 user     group           0 Sep 23 13:56 .."
//}
	if(count($arr)>=3)
	{
		for($i = 3;$i < count($arr); $i++)
		{
			$isdir =  substr($arr[$i],0,1);
			$filename = substr($arr[$i],55);//取文件名。
			$filename = "$dirName/$filename";

			echo "$isdir||$filename";
			echo "\r\n";
			if($isdir =="d")
			{
				removeDir($conn,$filename);

			}else{
				ftp_delete($conn,$filename);
			}
		}
		ftp_rmdir($conn,$dirName);
		return true;
	}else{
		return false;
	}
} 

6.上传一个文件

function ftp_upload_one($conn,$localfile,$remotefile)
{
	// 开始   
	$fp = fopen($localfile, 'r');   
	$ret = ftp_nb_fput($conn, $remotefile, $fp, FTP_BINARY);   
	while ($ret == FTP_MOREDATA)   
	{   
	   // 加入其它要执行的代码   
	   echo "....";   
	   // 继续传送...   
	   $ret = ftp_nb_continue ($conn);   
	}   
	if ($ret != FTP_FINISHED)   
	{   
	   echo "上传文件中发生错误...";   
	   exit(1);   
	}
	return true;
}

感觉php对ftp,命令行支持得很好。脚本写得很方便。
