What is %0d%0a?

[Anon]

I am parsing a file and using some of the information culled from it as the title of file that is being created. However, when I view the file in the browser, I see something like...

%0d%0aFile_title%0d%0a.php.

Is %0d%0a a special character of some sort? I tried

str_replace("%0d%0a", "", string)

but it does nothing. Now the strange thing is that when I view the file name through a terminal or in Midnight Commander (I'm using Linux) I see...

??File_title??.php.

So as a result, I also tried

str_replace("?", "", string)

and

str_replace("??", "", string)

to no avail. Now the File_title was culled using ereg() like this;

ereg("<!-- title -->(.*)<!-- end title -->", string, $content1).

Should I have retrieved the title in some other way? Is .* (which I barely understand anyways) grabbing more info than I am aware of?

Thanx in advance,
Terrence

I don't know why or how your browser is showing you that particular view of the data. Without having the actual file to examine all I can do is guess, but 0d is the hexadecimal value of a return and 0a is the hexadecimal value of a linefeed.

If your source HTML looks like this:

<!-- title -->
sometitle
<!-- end title -->

... then you're going to have junk to clean up. Replace \r and \n with nothingness.

If you're building a filename out of a free-text character string you probably should think about encoding the filename in some way to avoid getting illegal characters built into it.

Hi Steve,

Thanx for the info. I thought it was something along those lines, but just don't know enough to say for sure.

See ya,
