PHP中FTP相关函数总结

这篇文章主要介绍了php中ftp相关函数,涉及php操作ftp的连接、传输及文件与目录的相关操作技巧,具有一定参考借鉴价值,需要的朋友可以参考下

具体如下：

%s%s';
$items='';
foreach ($clist as $key=>$value){
$items .=sprintf($itemTPL,$value['name'],$value['detail']);
}
$bodyTPL='%s';
$data = sprintf($bodyTPL,$items);
  echo "\n".createFile(STORE_PATH, $saveFileName, $data);
}
set_time_limit(0);
$start_time = time();
$bookCache=array();
$categoryDir = "\\tingshu\\web";
getClassXml($conn_id,$categoryDir);
//获取顶级栏目
$clist = getDirListFormFtp($conn_id, $categoryDir);
//获取二级栏目分类
foreach ($clist as $key=>$value){
$_secondCateoryDir = $categoryDir.'\\'.$value['name'];
$_secondCateorylist = getDirListFormFtp($conn_id, $_secondCateoryDir);
$listData='';
$listTPL='%s%s%s';
$items ='%s%s';
$listItemString='';
//获取详细书籍章节列表
foreach ($_secondCateorylist as $key=>$book){
$listItemString.=sprintf($items,$book['name'], $book['detail']);
$_bookListDir = $_secondCateoryDir.'\\'.$book['name'];
$chapters = getBook($conn_id,$_bookListDir);
//生产book章节html
getBookofChapter ($book,$chapters);
//缓存bookid和章节信息
$bookCache[$book['name']] = array('category'=>$value['name'],'chapters'=>$chapters);
}
//生成二级栏目列表页
$listData = sprintf($listTPL, $value['name'], $value['detail'],$listItemString);
