PHP创建一个日期为文件名的.txt文件

Question

Is it possible to use date as a filename when creating/opening one with fopen? I have a form that writes user data to txt file, but I would like that everytime user submits info, new txt file is generated with date in file name.

Here is my try

$myfile='/home/myaccount/public_html/test/tiog/'.date('m-d-Y_hia').'.txt';
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $upisufajl);
fclose($fh);

Error I'm getting is

Warning: fopen() [function.fopen]: Filename cannot be empty in /home/...

And how could I encode it in UTF8, so that it supports special characters (čćšđž)?

Thanks

Jeremy, you are getting that error because your variable is misnamed:

$myfile= .... pen($myFile ....
   ^                 ^
   '-----------------'--------- see?

The second issue you have (regarding file encoding) is because text files are usually in plain ascii. If you want to save in UTF-8, it's perfectly fine...just make sure the string you are saving is in UTF-8.

Example:

file_put_contents($myfile, utf8_encode($upisufajl));
