how to know encoding of a string

[ldejesuspr]

Hi, I am dumping the content of a web page, I want to save an extract to a file. After I strip HTML tags and parse I write to a file the result.

When I see the file i contains more lines I supposse it has something to do with encoding.

The content in the file is:

 
576.15
 
 
 

I only want the second line, when I echo to screen I only see the "576.15"

Any ideas on how to get rid of the rest pefore writing to file?

thanks

Well firstly I have no idea exactly what you are doing you only told us the surface issue of the problem.

What code are you currently using?
What do you mean by encoding? From what I see there is no encoding just plain text from the result.

Ok, I'll elaborate

I getting the content of a page using cURL. From all that is contained in my result variable I only want a line so I proceed to parse and discard what is not needed. Once I have the line I want I write it to a file. This is the content of the file:

" "
576.15
" "
" "
" "

I quoted the lines because otherwise they do not appear, is like they were blanks.

If I echo the variable this is waht is printed: 576.15

How do I prevent this from being written in the file?

Again I see the characters are not displayed, I will separate with an "_"

 
576.15
