I want to write the content of a string variable say $data

in to a file named data.xml the folder location will vary depends upon the content of $appId variable

like i want to write file in 

  files_dir/$appId/data.xml

moreover if that file already exists than i want to rewrite otherwise i want to create the folder and then create the file data.xml

Can u suggest some way to do so.

Open file with write mode "w". will attempt to create file if does not exists otherwise truncate the file to zero length.

$handle = fopen("files_dir/$appId/data.xml", "w");

Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

You could check if the directory exists

if (!is_dir("files_dir/$appId")) mkdir("files_dir/$appId",0777);
$handle = fopen("files_dir/$appId/data.xml", "w");

Give the full path of directory and files.

You can use file_put_contents() to write to the file : http://php.net/manual/en/function.file-get-contents.php

And you can use mkdir() to create the folder portion : http://php.net/manual/en/function.mkdir.php
